Technical Description

The Komatsu WA380-7 wheel loader is a high-performance machine engineered for demanding loading and material handling tasks. Powered by a turbocharged Komatsu SAA6D107E-2 6-cylinder engine, it delivers 143 hp (107 kW) gross and 142 hp (106 kW) net power at 2,100 rpm, ensuring reliable performance and fuel efficiency. The loader features a full powershift transmission with four forward and four reverse gears, enabling smooth operation and a top speed of 40 mph (64 km/h) in both directions. Its hydraulic system utilizes a piston pump with a flow capacity of 36.2 gal/min (136 l/min) and a relief valve setting of 3,555 psi, providing responsive cycle times: 5.9 seconds to raise, 3.3 seconds to lower, and 1.8 seconds to dump. The rated bucket capacity ranges from 3.8 to 5.2 cu yds (2–4 m³), with a dump clearance at max raise of 9.7 ft (3 m). The machine’s operational weight is between 39,840 and 41,115 lbs (18,071–18,650 kg), supported by 23.5-25 tires and a 20.9 ft (6 m) turning radius for excellent maneuverability. Fluid capacities include 79.3 gal (299 l) fuel, 14.4 gal (53 l) cooling system, 6.1 gal (23 l) engine oil, 10.6 gal (38 l) front and rear axle/diff, 14.3 gal (53 l) transmission, and 37.5 gal (140 l) hydraulic system. The WA380-7 combines robust construction, advanced hydraulics, and operator comfort for efficient, productive operation in diverse environments.
