Komatsu’s 28,836-pound WA270-7 wheel loader achieves 10-percent lower fuel consumption compared to its predecessor, the WA250-6, our sister site, Equipment World, reported.
Powered by a Tier 4 Interim SAA6D107E-2 engine, the loader delivers 149 net horsepower and features Parallel Z-bar loader linkage with an offering of both a parallel lift linkage and high tilt forces; a 10-percent increase in lift force allows for quick and easy bucket loading.
For improved precision and air management and longer component life, Komatsu has included Komatsu Variable Geometry Turbocharger and an Exhaust Gas Recirculation. Plus, the diesel particulate filter allows for a high percentage of passive regeneration.
Other machine features include SmartLoader Logic, which adjusts engine torque to meet application needs; hydrostatic drive train that increases pump capacity, improves efficiency, boosts responsiveness and eliminates brake wear; traction control for performance on soft or slippery terrain; and a variable speed control system that allows the operator to set specific speeds.
The loader’s cab features lower glass than previous models, a redesigned seat-mounted right hand console with a multi-function mono-lever, an auxiliary input, two 12-volt ports and a 7-inch high-res LCD monitor.
Komatsu has simplified maintenance of the WA270-7 with the inclusion of convenient service access, increased cooling capacity, wider cooler fin spacing, an auto-reversing fan and Komatsu’s Equipment Management Monitoring System for diagnostics and troubleshooting.
