New EU Stage V compliant machine designed for high productivity and maximum comfort safety and efficiency
KOMATSU Europe International N.V. have launched the new WA800-8 wheel loader. Designed for maximum operating comfort and efficiency, the WA800-8 is said to offer many customer advantages, including a modulation clutch and variable traction control, an auto-kick-down and a rev/min set.
Weighing 115 tonnes, the WA800-8 features a redesigned extra-large 11.5 cubic metre bucket with optimized maximum fill factor, allowing for 20,700kg rated load capacity in a standard boom configuration
‘Our WA800 has always been well-appreciated for its reliability and productivity,’ said Jo Monsieur, group manager for large machines at Komatsu Europe, ‘and this latest generation surely continues this legacy. Furthermore, Komatsu have really set new standards for stability, comfort and safety, and we are very proud to be able to offer this to our customers.’
The Komatsu WA800-8 meets the latest EU Stage V emission regulations with Komatsu-designed, developed, and manufactured engine and aftertreatment systems comprising two diesel particulate filters, two variable-geometry turbos, a heavy-duty and cooled exhaust gas-recirculation system, new engine control modules, a closed crankcase ventilation system – with no AdBlue required.
A standard high-accuracy Payload Meter (PLM) monitors and tracks productivity and efficiency to within 1.5% accuracy, to avoid overloading dumptrucks.
The modulation clutch system gives the operator precise control of rim pull, for fast work equipment speeds, and a smooth approach for truck loading, whilst the variable traction-control system optimizes rim pull on all ground conditions, minimizes tire slippage and reduces maintenance costs.
On-board Komatsu SmartLoader Logic, a fully automatic engine control, yields precisely enough torque for each work phase, based on the application. By automatically switching between Economy and Power modes it considerably reduces fuel usage, with no loss of productivity.
The new-generation WA800-8 wheel loader’s hydraulics have been improved with a CLSS hydraulic system that delivers power on demand via the variable displacement piston pumps, keeping the hydraulic oil cool and increasing both work speed and fuel economy. Fuel savings are further promoted through the Auto Idle Shutdown system and by ECO guidance tips on the in-cab monitor.
A new supersized ROPS/FOPS cabin provides a completely redesigned, spacious, sturdy and safe operating environment, with a wide and unobstructed view of the work area. After dark, visibility and safe maintenance are improved by 22 LED lights – a comprehensive new standard factory-fit package.
For increased safety and operating confidence, KomVision, a visual aid designed by Komatsu to help avoid contacts or collisions due to blind spots, reduces risks of machine damage and injury. On the WA800-8, five network cameras create a bird’s-eye view of the immediate surroundings on a dedicated monitor. An extra rear-view camera sends a colour image with a distance indicator line on the cabin monitor.
Catwalks and handrails on the counterweight provide an additional standard safe exit and easier maintenance, whilst a hydraulically operated 45° ladder to the cabin is available as an option.
For easy servicing, even high up, technicians can attach lanyards to safe anchored tie-off points around the WA800-8. Standard safety lockout switches at the rear of the machine can be quickly reached from ground level, in an emergency or a critical situation.
Engine maintenance points are grouped and various ladders, stairs and handrails provide safe access to all filters. An optional service centre allows the wireless download of KOMTRAX Plus data, along with faster and easier oil servicing and sampling.
The radiators have a swing-out reversing hydraulic fan, for safe access and easy cleaning with compressed air or water. To reduce clogging, the modular core radiator features widely spaced cooling fins.
Brake life has been increased with an improved fully sealed hydraulic brake system, and the front frame and loader linkage have been redesigned to be stronger and more durable.
The redesigned interior of the new and enlarged cabin offers better ergonomics to reduce operator fatigue, with sound insulation and a quieter engine keeping noise levels low to help them stay focused and safe.
A new, fully adjustable, air-suspended, heated and ventilated seat with an adjustable bolster and integrated standard EPC levers makes life on site easier, as do the colour TFT monitor and a range of new tools and functions.
A new fold-up trainer seat allows in-cab operator training. For less experienced operators or just for easy operation, the Auto Digging system, the Semi-Auto Approach and the Semi-Auto Dump can assist to provide a consistent performance.
The new right-hand side console is integrated in the seat. Switches and Bluetooth radio are easily accessible on the overhead console, and the new front panel is styled with a similar look and feel to other Komatsu machines.
