Drones have opened a new frontier of mapping and inspection possibilities for the civil construction industry, according to Nick Smith, CEO of Airsight Australia.
Mr Smith has almost a decade of experience in the commercial drone industry, immersing himself in drones long before they entered the mainstream. He began development of the business model for his current company, Airsight Australia, in 2009, and since launching it in 2012, he’s recognised the transformative power of the technology for the civil construction industry.
“As a geospatially-focused toolkit, the potential is nearly limitless,” Mr Smith said.
The range and maneuverability of drones greatly facilitates the assessment of job sites during each stage of the building process, from the bid phase through to site planning and full construction.
“Being able to understand what is on a site prior to and during construction can really give management an edge in terms of a thorough understanding of what that site looks like, and what the potential risks are to the construction process,” Mr Smith said.
“It can also be highly valuable from both a quality control and accounting standpoint to be able to track progress during construction with regular aerial surveys.”
Ahead of his upcoming participation on the ‘Digital Engineering and the future of technology’ panel at the National Construction Equipment Convention (NCEC), Mr Smith said drones should be looked at not as a replacement for traditional work and data acquisition methods, but as an improvement on them. Gathering mapping data and conducting surveys on sites is already common practice; where drones excel is in how that data is acquired and processed.
“If you send a worker out, it could take them half a day or more just to cover a site and collect the required information, in addition to the physical obstacles or hazards they might have to deal with,” Mr Smith said.
“With a drone, we can be on site in the morning, capture data by mid-morning, and process and deliver it by the end of the day, if not sooner.”
“The expediency and quality of actionable data goes up, while safety risks to people on site goes down.”
Mr Smith said that some of the most exciting new developments in the use of drone data relate back to the accessibility of unprecedented amounts of information now available — and specifically, how that data is processed.
“Machine learning is making it possible to automate data analysis,” Mr Smith said.
“We’re already seeing artificial intelligence utilised for predictive maintenance and analytics, and we’re now starting to be able to identify defects and predict anomalies before they become large-scale problems. When you apply this to safety — predicting a rock fall before it happens, for instance — these technologies could literally save lives.”
The National Construction Equipment Convention will run from 15-17 November at the Sydney Showground. With a theme of ‘Think Globally, Act Locally’, the event will feature expert speakers and industry-leading companies discussing the opportunities and challenges in civil construction.

Road Widener LLC manufactures unique road maintenance attachments designed to significantly decrease your operating costs whilst delivering excellent performance, productivity and efficiency.
Road Widener’s FH and FH-R units have recently entered the Australian market and are rapidly growing in popularity within the road construction industry. These innovative machines are the most cost effective and efficient tools for shouldering, road widening, backfilling asphalt, trench backfilling, and kerb backfilling in Australia. Manufactured in the USA, Road Widener LLC has sold hundreds of units in its home market and has refined its design over nearly 10 years to best meet customer needs.
Whilst smaller than traditional road wideners, the FH and FH-R models are big on benefits, quality and features. All attachment functions are hydraulically controlled on both models, with adjustable box width, slope, and belt speed. They are designed with ease of use and visibility in mind, providing the operator with a clear line of site to the working area and road edge. The Road Widener is easily manoeuvred around guardrails, sign posts, mailbox posts and other obstructions.
Both models come standard in a left-hand discharge configuration in Australia, and a dual discharge model is also available, allowing optional right or left discharge in a single unit. The FH-R model adds an innovative remote-control functionality, allowing either the skid steer operator or another worker to control the Road Widener functions remotely. Both models lay aggregate at widths of 30-130cm and are powered by standard flow hydraulics. The Road Widener is suitable for use with any brand of large framed skid steer or compact track loader and can be optionally adapted to suit small wheel loaders or large tractors.
At only 1400kg, the Road Widener is easily transported, and can be lifted both off and onto transport trailers by a skid steer or track loader alone – no need for cranes or other logistical hassles commonly required by alternative heavier road widening attachments. All models offer precise operator control of the flow and placement of material, and with standard pintle push plates and wheel rollers, are able to disperse a 20-tonne truck load of aggregate in only minutes.
The Road Widener suitable for use with any type of aggregate, including gravel, asphalt and top soil, which is dispersed via the highest quality heat-treated conveyor belt designed for heavy-duty handling of hot asphalts and coarse materials alike.

Komatsu has released a new 50 tonne class excavator, the PC490LC-11, featuring a Tier 4 Final-compliant low emission engine, and delivering increased production and lower fuel consumption.
Designed for heavy construction, quarrying and demolition applications, the PC490LC-11 has an operating weight of 48.7 tonnes and is powered by a Komatsu SAA6D125E-7 engine rated at 270 kW.
According to Amber Rickard, Komatsu’s National Business Manager – Construction, the PC490LC-11 replaces the 46.1 tonne PC450LC-8, which it significantly outperforms in key operating criteria.
“These include a larger maximum bucket size of 2.7 cu m, a 15% increase in lift capacity, and up to 13% greater production and 15% better fuel efficiency with its enhanced power mode,” she said.
The new PC490LC-11 incorporates a number of major improvements and new features compared with its predecessor.
“Our new PC490LC-11 represents a complete redesign over the PC450LC-8,” said Rickard.
“Not only does it have a new Komatsu Tier 4 Final compliant low emission engine – which dramatically cuts emissions compared with Tier 3 and earlier engines – but our design engineers have greatly enhanced the hydraulic system for increased power and efficiency, and significantly beefed up the undercarriage, swing system and counterweight.
“We’ve improved hydraulic efficiency through higher-displacement pumps, providing increased flow output at lower engine RPM, which allows the engine to operate at its most efficient speed, and we’ve increased hydraulic pipe size diameters to reduce hydraulic pressure loss.
“The PC490LC-11 is also the only excavator in this size class with a closed-centre load-sensing system, for better fuel efficiency, improved fine control and simultaneous multiple functions,” she said.
“And in addition to standard hammer and quick hitch piping, the PC490LC-11 now comes with an additional service valve for easy setup of a proportionally controlled secondary auxiliary line.”
Much of the increased operating weight of the PC490LC-11 compared with the PC450LC-8 is due to a heavier counterweight and extra heavy duty undercarriage.
“The heavier counterweight and more robust undercarriage increase lift capacity by up to 15%, allowing the use of larger buckets and attachments, and for the machine to lift heavier loads around sites,” Amber said.
“In addition, this heavier duty undercarriage provides added durability and improved operator comfort in tough working conditions such as quarries, demolition and heavy construction, and rock-breaking work.
“The end result is an excavator that delivers lower costs per tonne, through its higher productivity and improved fuel efficiency, matched with durability and maintenance features that significantly reduce machine downtime and service costs,” she said.
“These machine features, combined with Komatsu’s industry-leading levels of service and support, including our Fix It First Time concept, KOMTRAX, our InSite Fleet Management Centre and Komplimentary Maintenance offering, all contribute to bringing down operating costs for Komatsu machine owners,” said Rickard.
Brief specs of the PC490LC-11 are: Operating weight, 48,690 kg; engine, Tier 4 Final-certified Komatsu SAA6D125E-7 engine rated at 270 kW; bucket size range, 1.45-2.7 cu m; maximum dig depth, 7755 m (3380 mm arm option); bucket breakout, 24,400 kgf; arm breakout, 20,900 kgf.]]>
Takeuchi has released its all-new TB225 2.3 tonne mini excavator, the latest model in its mini excavator range. The machine’s 1,330 cc 16.5 kW Yanmar diesel produces 16.5 kW of power; a significant increase in performance compared with earlier comparable Takeuchi models.
The TB225 is the largest machine in the market where track width can be reduced to a handy 1,100mm to access internal door openings and very narrow side access of structures. When the excavator’s tracks are fully expanded to 1,500mm, this provides the stability needed to get the optimum performance and productivity from the extra hydraulic power and bucket digging force of 19.3 kN.
The TB225 has a long undercarriage and ground clearance of 190 mm and the 1,790 mm of track-to-ground contact makes for better flotation. Triple-flanged rollers keep the tracks in place to deliver positive traction on high gradients.
Dual auxiliary hydraulic lines produce hydraulic flow at up to 38.5 l/m, operating three working pumps, including a slew/blade pump that improves operational speed and functional control.
The machine’s standard long arm gives a digging depth of 2,580 mm and at ground level, enables the bucket reach to 4,240 mm and dump loads at a height of 2,875 mm.
The TB225 incorporates loads of other features such as auto engine and hydraulic detent function pre-set flow to suit your attachment applications. Other features include proportional controls, smooth hydraulic pilot joystick controls that deliver precise action, two-speed travel with automatic shift, a blade that’s adjustable without tools, auto deceleration and a hydraulic piloted travel lever.
Large, lockable service covers let you access components at ground level and service points are conveniently located. Finally, the TB225 is still within the weight limit that lets you tow your machine behind a 3.5 tonne capacity ute. Semco Equipment Sales 1 800 685 525 or ww.semcogroup.com.au.]]>
Enhanced safety with increased productivity and outstanding fuel economy gains are key reasons why Timberlink, Tasmania, specified two new Volvo wheel loaders to manage their high throughput log yard operation.
Timberlink’s modern Bell Bay operation is the only large scale, forest integrated plantation softwood Sawmilling Company located in Tasmania where they produce their widest range of commodities. The product mix includes structural framing, outdoor structural framing, fencing, landscaping, decorative timbers and industrial supplies. They directly employ over 200 people and engage predominantly local contractors and businesses to support their Bell Bay operation. The indirect contribution to the local economy is estimated at $150M.
Timberlink Bell Bay in conjunction with their treatment supply partner Lonza, developed their innovative “Low Odour Timberlink Green” range of products. The new patent pending product is a world first with 30 times less odour, which creates a more pleasant workplace for customers and end-users while still retaining the superior strength, stability and appearance of traditional LOSP products.
Today timber in Australia is in high demand.
At Timberlink’s Bell Bay sawmilling operation, Log Yard Supervisor, Dean Smith believes that adopting new technologies and specifying components according to need rather than tradition, will lead to higher profits for the company, despite timber prices almost remaining static for the last decade, due in no small part to cheaply imported products.
Smith monitors the processes and movements in the log yard with the sharpened pencil of an accountant. Combining a broad knowledge of the sawmilling industry and his understanding of production practices with consideration for future demands, he configures his loaders to safeguard the highest interests of the company.
“We found the CJD team to be very proactive in working with us to agree on the specification of the L220H and L180G and checking all the details were correct to ensure the machines would do ‘what it says on the tin’. The overall package was very competitive too so all in all this prompted us to choose Volvo once again.”
Dean Smith and his team are no strangers to operating Volvo equipment, having previously run an L180C wheel loader in another sawmilling operation, where they were impressed with the reliability and economy of the Volvo machine.
Specifying the L220H as the main loader in the log yard increased productivity considerably because it is more than capable of lifting an entire bay of logs off a truck in one lift.
“The power of the L220H gives us greater efficiencies through increased productivity and fuel economy gains because the machine isn’t working beyond its capability,” operator Scotty Harris said. “We can unload and stack a B-Double load of logs in under eight minutes with either machine.
“We’re very pleased with our turn around time for unloading, on average, from the time a log truck arrives at the weighbridge, they can be unloaded and back on the weighbridge within 15-mintues,” Scotty added.
“The L180G is used as a secondary machine in the log yard,” Dean explained. “Its more than capable of keeping the mill fed with fresh logs and equally at home unloading log trucks. Being a little smaller gives it the agility to perform other tasks around the mill and the simplicity of the quick hitch attachments makes swapping from the log grapple to a bucket a quick operation and adds to the machine’s versatility.”
The new L220H model is powered by a 13-litre Stage IV Final engine (373hp) and benefits from Volvo designed and manufactured driveline components, including the company’s Optishift system with torque converter lock-up and reverse-by-braking features – all designed to deliver better fuel economy.
Meanwhile, a 13-litre D13F-C engine (334hp) powers the L180G, a mere 39 horsepower less than the L220H.
In addition to the productivity gains, the Volvo wheel loaders also have an ROPS/FOPS operator’s cabin with a fully adjustable suspension seat. The cab is fully air conditioned, and all critical machine functions are displayed on an LCD screen located within the operator’s field of vision.
Operator Scotty Harris cites the rear view camera as a great asset and safety feature especially with the addition of the blue light for night work.
He adds that the dash panel clearly displays all the vital machine information including fuel and oil levels along with warning messages even in bright sunlight all at a glance without hindering forward vision.
Volvo’s load-sensing hydraulics are said to be at the forefront in artificial intelligence, by supplying power to the hydraulic functions according to demand, further lowering fuel consumption. The powerful hydraulic system ensures fast response for shorter cycle times while delivering smooth operation through superior control of both the load and the attachment.
Volvo’s unique eco pedal applies mechanical push-back force when the accelerator is used excessively and engine RPM is about to exceed the economic operating range. This encourages the operator to ease off the throttle, reducing fuel consumption.
“I normally run the loader at 1400 RPM around the log yard, but increase the revs to 1600 RPM when going up the ramp with a full grab of logs,” Scotty explained. “I’ve found this gives good economy while still achieving maximum productivity.”
For ease of operation, Timberlink specified the optional, multi-functional joystick, which gives their operators simultaneous and precise control of the hydraulic functions. Forward, reverse and kick-down functions are included on the console.
As you’d expect on a loader working in a log yard, Volvo’s unique Torque Parallel (TP) linkage is a huge advantage, delivering high breakout torque and excellent parallel movement throughout the entire lifting range.
Timberlink specified the optional Boom Suspension System (BSS) that enables faster and more comfortable work cycles to further increase productivity and safety while at the same time extend the machine’s life. That’s because Volvo’s unique BSS absorbs shock and reduces the bouncing that occurs when operating on rough ground such as a log yard.
Scotty Harris believes that the cabin environment is one of the best he’s experienced. “It’s certainly one of the more spacious cabs in this class of loader yet all the controls are sensibly positioned within easy reach. It is also very quiet in the cabin and the smooth ride means I’m not exhausted at the end of the shift. One thing these Volvo loaders do well is remove the dust in the air,” Scotty revealed.
Volvo has located the cabin air intake high on the machine, where air is cleanest. There is an easy to replace pre-filter that separates coarser dust particles before the air passes through the main filter and finally enters the cabin. The design of the Volvo air system allows 90 per cent of the cabin air to be recirculated through the main filter for continuous dust removal.
The engine bay features a hydraulically driven reversible cooling fan that is electronically controlled to regulate the temperature of the vital components. It automatically activates only when it’s needed further reducing fuel consumption and noise. The reversible functionality which blows air in the opposite direction, allows for self-cleaning of the cooling units.
Both the front and the rear axle feature an axle oil circulation feature that allows the axle oil to flow and cool inside the axle protecting vital components.
“Our two Volvo loaders are enrolled in the CareTrack program and CJD monintor the machines via satellite,” Dean Smith explained. “They (CJD) know how each machine is going at any given time and when servicing is required which allows us to focus on what we are good at and that’s sawmilling.”
“Our decision to invest in Volvo Construction Equipment was essentially based on a productive, economic and reliability package with on-going back up support,” Dean concluded. “Those two machines average 90 hours each per week and in their first 12 months had each clocked up almost 5500 hours. Consequently, we’re certainly pleased with the partnership we have with CJD in Launceston which includes onsite service and maintenance.”
Komatsu has released two new
s, the 28-tonne capacity HM300-5 and 40-tonne capacity HM400-5, both powered by low-emission Tier 4 Final engines and featuring Komatsu’s advanced truck transmission system.
The 28 tonne capacity HM300-5 is powered by Komatsu’s SAA6D125E-7 engine rated at 242 kW net, while the 40 tonne HM400-5 is powered by the SAA6D140E-7 rated at 348 kW net.
Both engines are US EPA Tier 4 Final emissions certified, cutting both nitrous oxide (NOx) and particulate matter (PM) emissions by 90% compared with their Tier 3 equivalents, while delivering up to 14% lower fuel consumption compared with previous models.
These engines incorporate an advanced electronic control system that performs high-speed processing of all signals from sensors installed in the vehicle, providing total control of equipment in all conditions of use.
Engine condition information is displayed via an on-board network to the monitor inside the cab, providing all necessary operating data to the operator.
Additionally, this data can be accessed and managed via the KOMTRAX telematics remote monitoring system (supplied as standard on all Komatsu construction and utility machines), ensuring owners and fleet managers stay well on top of all maintenance requirements.
According to Richard Feehely, Komatsu Australia’s National Business Manager, Quarries, Komatsu’s new Tier 4 engines monitor and transmit far more detailed data about engine conditions and operation, giving unmatched visibility into the health of equipment – and any potential issues.
“And through our in-house development and production of engines, electronics, and hydraulic components all designed to work with each other, Komatsu has achieved major advances in technology, providing high levels of performance and efficiency across all applications,” he said.
“Because of this integrated design approach, we have been able to achieve further reductions in fuel consumption with these new trucks,” Richard said.
“These include the use of variable displacement piston pumps that use engine power only as needed to eliminate unnecessary PTO inefficiencies, along with design improvements to the drive axles and transmission systems that reduce parasitic driveline losses.”
Both new trucks feature Komatsu’s advanced truck transmission system, including its electronically controlled K-ATOMICS countershaft transmission which is also used on large mining trucks, and the Komatsu Traction Control System (KTCS).
“Both these features are unique to Komatsu articulated dump trucks and, combined with our hydraulically controlled wet multiple-disc brakes and retarder system, provide unrivalled traction, braking power and safety in all types of operation,” Richard said.
K-ATOMICS incorporates an electronic clutch modulation system that ensures proper clutch pressure when the clutch is engaged.
“This total control system controls both the engine and the transmission by monitoring the vehicle conditions, ensuring smooth shifts with minimal shock and thus maximises powertrain life,” he said.
“KTCS, which we have derived from our extensive experience in traction control systems in dozers and rigid dump trucks, was developed by Komatsu to ensure maximum machine performance in soft and slippery ground conditions.
“This system, which is automatically activated and deactivated, monitors wheel speeds on the front and middle axles, and if it detects wheel slip, will automatically engage the inter-axle lock to improve machine performance.
“If the machine continues to detect wheel slip, it will brake the wheel that slip was detected on, continually monitoring wheel speeds and engaging the brakes as necessary,” he said.
Both trucks also incorporate Komatsu’s exclusive hydraulic braking and retarder system, which ensures complete control even when doing downhill fully loaded.
“Large-capacity, continuously cooled, wet-multiple disc brakes, which have been proven on other Komatsu rigid dump trucks, also function as a highly responsive retarder, giving the operator full control when travelling downhill,” said Richard.
Retarder absorbing capacity (continuous descent) is 392 kW on the HM300-5 and 510 kW on the HM500-5.
They also both come as standard with a payload meter (PLM), which displays payload tonnage as the truck is loaded. This information is visible to the operator, and is also transmitted to owners and fleet management via KOMTRAX.
Both trucks feature large ergonomically designed ROPS/FOPS cabs with air suspension seats and hydro-pneumatic front axle suspension, while the centrally located operator seat and short-bonnet design ensures excellent visibility of the working area. A rear-view camera and in-cab monitor are also provided as standard.
Maintenance requirements have been made easier on the two trucks through features such as ground-level fuel filter access, power-tiltable cab, reversible engine cooling fan, battery disconnect switch and an electric fuel priming pump.
“Since we introduced our HM400-3M0 in Australia in 2014, it has proven itself as a highly productive, efficient and safe articulated hauler across a wide range of applications,” said Richard.
“Now with our launch of these latest low-emission versions of the HM300-5 and HM400-5 trucks, customers can take advantage of the benefits of the latest Komatsu technology for their haulage operations.”
Brief specs of the two trucks are as follows:
HM300-5:Payload capacity, 28 tonnes; body capacity, 17.1 cu m; engine, Komatsu SAA6D140E-7 engine EPA Tier 4 Final emissions certified, rated at 242 kW net at 2000 rpm; transmission, automatic countershaft with lockup torque converter, 6F/2R speeds; maximum speed, 58.6 km/h; tyres, 23.5 R25; loading height, 2830 mm; width, 2900 mm; overall length, 10,275 mm.
HM400-5:Payload capacity, 40 tonnes; body capacity, 24 cu m; engine, Komatsu SAA6D125E-7 engine EPA Tier 4 Final emissions certified, rated at 348 kW net at 2000 rpm; transmission, automatic countershaft with lockup torque converter, 6F/2R speeds; maximum speed, 55.9 km/h; tyres, 29.5 R25; loading height, 3164 mm; width, 3450 mm; overall length, 11,105 mm.
Komatsu has released two new low-emission zero-swing mid-size excavators, the 7.94 tonne PC78UU-10 and the 8.75 tonne PC88MR-10, delivering higher productivity and power while consuming less fuel than their predecessors.
They are powered by Tier 4 Final-compliant Komatsu SAA4D95LE-6 engines, rated at 49 kW for both machines, and feature new engine and hydraulic system control technology to reduce fuel consumption and significantly increase worksite efficiency.
According to Carl Grundy, Komatsu’s National Sales Manager – Utility, the two new excavators incorporate significant technology and performance advances over their Dash 8 predecessors.
“These two excavators have been renowned for being incredibly versatile and productive machines, ideally suited for excavation, rock work and services placement in confined urban areas; with these latest improvements, they are even more productive and efficient, while being less expensive to own and operate,” he said.
“Both new units are built with tight access in mind, the PC88MR-10 – MR stands for ‘minimum radius’ – with its swing boom design has a tailswing protrusion of just 325 mm while the PC78UU-10 – UU is for ‘ultra urban’ – features an offset boom design ideal for the tightest worksite.
“Our environmentally friendly Komatsu SAA4D95LE-6 Tier 4 Final engine drastically reduces emissions compared with the previous machines’ Tier 3 engine, while reducing fuel consumption by up to 5%.”
To achieve these lower emissions, while also lowering fuel consumption, the engines include newly designed variable flow turbochargers, cooled exhaust gas recirculation, a Komatsu diesel oxidation catalyst, and an advanced engine control system.
“With this engine design there is no need for DEF (Adblue) or a diesel particulate filter (DPF), further reducing maintenance and running costs of these machines,” said Grundy.
This advanced electronic control system also incorporates enhanced reporting and diagnostic capabilities, with detailed engine condition information displayed via an on-board network to the monitor inside the cab, providing all necessary operating data to the operator.
Additionally, this data can be accessed and managed via the KOMTRAX telematics remote monitoring system (supplied as standard on all Komatsu construction and utility machines), ensuring owners and fleet managers stay well on top of all maintenance requirements.
Komatsu has also increased engine power 16% on the PC78UU-10, for higher site productivity.
Both machines incorporate new Komatsu technology to enhance the engine and hydraulic pump control.
“Our total control system matches the engine and hydraulics at the most efficient point under any load condition,” Grundy said.
“At the same time, there have been improvements in the main valve and hydraulic circuits to reduce hydraulic loss, resulting in higher efficiency and lower fuel consumption.
“Overall, with these two machines we are seeing up to 5% lower fuel consumption, combined with up to 3% higher productivity.”
To further improve jobsite productivity and efficiency, both machines offer six working modes: power, economy, lifting, breaker, attachment power and attachment economy mode.
“Each mode is designed to match engine speed, pump flow, and system pressure to the application, so that the most efficient combination of engine and hydraulic power is used,” he said.
“We’ve also included some operator aids to encourage fuel-efficient operation at all times.
“These include an ECO gauge to assist in reducing fuel consumption during operation, a idling caution if the engine idles for more than five minutes, and idle auto stop function that automatically stops the engine if it idles for more than a set period of time.”
Both machines are fitted with integrated ROPS cabs with OPG2 protection offering ample operator space, and with wide doorways for easy access. An automatic air conditioning system is standard, as is a colour reversing camera.
For ease of maintenance, component access has been optimised with all major maintenance points accessible from ground level, while remote mounting of the engine oil filters, main fuel filters and fuel drain valves simplifies these tasks.
“Our two new mid-size zero-swing excavators have long set the industry standard in this class of machine; the improvements and advances with these Dash 10 models make them even more productive and efficient, while being significantly cheaper to own and operate,” said Grundy.
Brief specs of the two new Komatsu excavators are:
:Operating weight, 7940 kg; engine, Tier 4 Final-certified Komatsu SAA4D95LE-6 rated at 50 kW; bucket size range, 0.28-0.34 cu m; maximum dig depth, 4230 mm; bucket breakout, 6250 kgf; arm breakout, 4230 kgf.

If looking for proven performance, more comfort options and better design to maximise uptime, the revolutionary line-up of R-Series excavators demand attention.
In addition to increased over-the-side stability, a high quality finish and unbeatable operator experience, Bobcat R-Series models can be configured with industry-exclusive features. With the help of the unique Pro Clamp system, extendable arm, and depth check system, it’s never been easier to tackle a variety of jobsite challenges.
BobcatDepth Check System
To prevent time wasted on over-digging or under-digging, Bobcat Company developed its first depth check system for compact equipment. This avoids the need to manually check the grade or depth with a tape measure or ‘stick’ receiver, and eliminates the need to set up laser equipment for smaller excavation jobs.
Efficient and easy to use, the system delivers accurate dig depth measurement for precise digging performance. It eliminates over-digging and the costs associated with backfilling and compacting fill material. It also prevents under-digging and the resulting need for manual labour to finalise depth or grade.
The system is ideal for:
Utilising sensors that detect the exact position of the bucket’s teeth, the Bobcatdepth check system allows operators to set a desired digging depth and works against that benchmark. The integrated panel continually references the current and desired depths, while audible alerts indicate whether the operator is approaching the target, at the target, or beyond the target. On larger jobsites, an optional laser receiver offers operators greater flexibility to move around, benching off a laser signal rather than a fixed grade point.
Unlike other systems, the Bobcat depth check system integrates with the deluxe instrument panel. This offers simple operation and eliminates the need for an add-on display monitor inside the cab.
With a Bobcat excavator and the depth check system, operators spend less time checking depth and more time digging. It’s just another way Bobcat makes jobs easier and quicker.
