The 126-horsepower WA200-7 wheel loader incorporates Komatsu’s Parallel Z-bar (PZ) loader linkage and replaces both its WA200-6 wheel loader and WA200PZ-6 tool carrier predecessors. The new loader uses a Komatsu’s Tier 4-Interim engine, which, the company says, delivers 3 percent better fuel economy, compared with the WA200-6. With a maximum operating weight of 26,070 pounds, the WA200-7 features Komatsu’s second-generation hydrostatic drive system with traction-control and variable-speed control.
According to Komatsu, the PZ loader linkage combines the advantages of parallel-lift linkage for pallet handling with the advantages of the Z-bar linkage’s high tilt forces for handling large attachments. The ample breakout and lift forces of the PZ linkage, says Komatsu, assist in fast bucket loading and aggressive digging performance.
The Tier 4-Interim engine uses an electronic control system to manage fuel injection, airflow rate (via a variable-flow turbocharger), combustion, and the exhaust after-treatment system. Electronic management of these parameters, says Komatsu, optimizes engine performance, lowers emissions, and reduces fuel consumption.
The WA200-7 also features the Komatsu SmartLoader Logic system, designed, says the company, to provide optimal engine torque for the specific application and thus to save fuel by automatically decreasing engine torque when the machine is involved in lighter-duty applications.
Komatsu’s second-generation, electronically controlled hydrostatic drive system in the WA200-7 has increased pump capacity, provides dynamic braking, and features the Komatsu traction control system, designed to facilitate operation on soft or slippery ground. Traction settings step down torque delivered to the wheels, an S-Mode sets the machine up for working on ice, and a Max-Mode restores full traction. The variable-speed-control feature allows setting maximum speed between 3.2 and 8.9 mph during applications such as mowing or broom use.
The Komatsu EMMS (Equipment Management Monitoring System) provides enhanced monitoring and diagnostic features for the WA200-7, and Komatsu CARE provides complimentary scheduled maintenance for three years or 2,000 hours. The KOMTRAX telematics system wirelessly sends machine operating data to a secure website or smart phone application and reports such items as operating hours, fuel consumption, location, cautions, and maintenance alerts.
