1996-2006 KOMATSU WA95-3 WHEEL LOADER

Technical Description

The Komatsu WA95-3 is a compact wheel loader designed for versatility and efficiency in material handling. It is powered by a 4-cylinder 4D 106 E 2 diesel engine delivering 75 hp (56 kW) at 2500 rpm, with peak torque at 1500 rpm, ensuring reliable performance. The loader has an operating weight of approximately 12,192 lbs (5,530 kg) and features a hydrostatic transmission with two forward gears, providing a maximum speed of 12.5 mph (19 kph). The loader’s bucket has a breakout force of 16,298.7 lbs (7,393 kg) and a heaped capacity of 1.5 cubic yards (1 m³), with a width of 7.1 ft (2 m). It offers a dump clearance of 9 ft (3 m) at maximum raise height and a hinge pin height of 11.4 ft (3 m), allowing efficient loading and stacking. The wheelbase measures 7.1 ft (2 m), with a total length of 18.3 ft (5 m) including the bucket, and a turning radius of 13.3 ft (4 m), facilitating maneuverability in tight spaces. The WA95-3 utilizes a closed hydraulic circuit with a pump flow capacity of 23.8 gal/min (87 l/min), achieving lift, lower, and dump times of 5.7, 3.7, and 1.1 seconds respectively. Hydraulic relief valve pressure is set at 2755.8 psi. The loader operates on a 12 V electrical system supported by an 80 A alternator. Fluid capacities include 34.4 gallons (129 l) of fuel, 24.9 gallons (91 l) hydraulic fluid, 4.5 gallons (15 l) cooling fluid, and 4.4 gallons (15 l) engine oil. Tire size is 455/70 R 20 SPT9, with rear axle oscillation of 24°, enhancing stability on rough terrain. Ground clearance is approximately 1.7 ft (0.5 m), and the cab height stands at 9.1 ft (3 m), providing good operator visibility and comfort. This loader balances power, size, and hydraulic efficiency for medium-scale construction and industrial applications.
