ZETTELMEYER ZL402 WHEEL LOADER

Technical Description

The Zettelmeyer ZL402 is a compact wheel loader designed for versatility and performance in construction and industrial applications. It is powered by a naturally aspirated KHD F 3 L 1011 three-cylinder diesel engine with a displacement of 125 cu in, delivering a gross power of 37.6 hp (28 kW) at 2300 rpm and net power of 36.3 hp (27 kW). The engine provides maximum torque at 1800 rpm, ensuring efficient power delivery for demanding tasks. The hydrostatic full power shift transmission offers two forward and two reverse gears with a maximum speed of 12.5 mph (19 kph), facilitating smooth and precise maneuvering. The machine features a bucket with a breakout force of 7,419 lbs (3,365 kg), a heaped capacity of approximately 0.7 cubic yards (0.5–1.0 cu m range reported), and a bucket width of 5.5 ft (1.8–2 m). The bucket achieves a dump clearance of 8 ft (2.4 m) at maximum raise and a hinge pin height of 9.8 ft (3 m). Hydraulic actuation times include a 6-second raise, 5-second lower, and 2.5-second dump, supported by a gear-type hydraulic pump with an 8.5 gal/min (30 l/min) flow capacity and a relief valve set at 3050 psi. Dimensionally, the loader has an operating weight around 7,500 lbs (3,402 kg), a wheelbase of 6.1 ft (1.85 m), width over tires of 5.3 ft (1.6 m), and a ground clearance of 1.1 ft (0.33 m). It runs on 10.5-18 pneumatic tires, with a turning radius of 12 ft (3.7 m), and features 20° rear axle oscillation enhancing stability on uneven terrain. Fuel capacity is 11.1 gallons (42 l), supporting extended operation times. The ZL402’s dimensions and power combine to facilitate robust performance in tight work environments requiring reliable lifting and loading capacities.
