Technical Description
The Komatsu WA700-3 With AJSS is a heavy-duty wheel loader engineered for surface mining and large-scale earthmoving tasks. It features a powerful 6-cylinder, turbocharged and aftercooled SAA6D170E-3 engine delivering 672 hp (501 kW) at 2,000 rpm, coupled with a fully automatic 4-speed power-shift transmission enabling forward speeds up to 18.7 mph (30 km/h) and reverse speeds up to 20.1 mph (32 km/h). The loader’s robust hydraulic system includes a piston pump with 107 gal/min (405 l/min) flow capacity, 4550 psi relief valve setting, and efficient cycle times: dump in 2.5 seconds, lower in 3.6 seconds, and raise in 9.7 seconds.
The machine’s bucket offers a heaped capacity of 11.4 cubic yards (8 m³) and a struck capacity of 9.9 cubic yards (7 m³), with a 15 ft (5 m) width, providing extensive material handling capability. Maximum dump clearance at full raise is 14.2 ft (4 m), with a reach of 6.3 ft (2 m). The WA700-3’s dimensions include a 15.9 ft (5 m) cab height, 39.9 ft (12 m) length with bucket on ground, 13.4 ft (4 m) width over tires, and a 15.8 ft (5 m) wheelbase, balanced by a ground clearance of 2 ft (1 m) for stable operation on uneven terrain. Operating weight is approximately 156,570 lbs (71,020 kg).
Advanced Joystick Steering System (AJSS) enhances operator control with ergonomic, low-effort electronic pilot controls integrating steering and transmission functions for precision maneuvering. The WA700-3 includes heavy-duty axles with full-floating design, 41.25/75-39 tires, and a cooling system capacity of 57.9 gallons (216 liters), supporting continuous high-performance operation in demanding environments. Fuel capacity is 290.6 gallons (1,098 liters), making it suitable for extended use without frequent refueling. This loader is optimized for reliability, maintenance access, and operator comfort.
