LIEBHERR L550 WHEEL LOADER

The Liebherr L550 wheel loader is engineered for versatile material handling with a heaped bucket capacity of 4.2 cubic yards (3 m³) and an 8.1 ft (2 m) bucket width. It features an 8.6 ft (2 m) arm length and delivers a breakout force of 31,475.5 lbs (14,277 kg), ensuring strong digging performance. The maximum hinge pin height reaches 12.1 ft (4 m), enabling efficient loading and dumping with a dump clearance of 9.5 ft (3 m) at max raise. The loader measures 27.2 ft (8 m) in length with the bucket on the ground and has a wheelbase of 10.1 ft (3 m), with a ground clearance of 1.7 ft (0.5 m) and overall height at the cab top of 11 ft (3 m). Powered by a 4-cylinder Liebherr D934 A7 engine with 428 cu in (7 L) displacement, it delivers 173 hp (129 kW) at 1500 rpm and a max torque of 622 lbs/ft at 1300 rpm. The engine incorporates water cooling, exhaust turbocharging, externally cooled exhaust gas recirculation, and a diesel particulate filter for emissions control. It features electronic high-pressure common rail fuel injection and a dry air filter system. The hydraulic system includes a load-sensing variable axial piston pump with 62 gal/min (235 l/min) flow, pressure cut-off control, and relief valve setting at 4351.2 psi, with dump, raise, and lower times of 2.3, 5.5, and 2.7 seconds, respectively. Fuel capacity is 79 gallons (299 l). The 3-forward and 3-reverse speed transmission enables a top speed of 24.9 mph (39 kph). The machine weighs 38,140 lbs (17,300 kg), rides on 23.5R25 L3 tires, and has a turning radius of 21.2 ft (6 m), providing robust performance and maneuverability for heavy-duty industrial applications.
