Technical Description
The Liebherr L554 2PLUS2 is a robust wheel loader featuring a breakout force of 29,225 lbs (13,256 kg) and a heaped bucket capacity of 4.6 cubic yards (3 m³) with a bucket width of 8.9 ft (2 m). The loader offers a dump clearance at maximum raise of 10.2 ft (3 m) and a maximum hinge pin height of 13.8 ft (4 m). It has a length of 26.7 ft (8 m) with the bucket on the ground, a wheelbase of 10.4 ft (3 m), and ground clearance of 1.8 ft (0.55 m). The cab height is 11.1 ft (3 m), while the reach at max lift and dump is 3.6 ft (1 m).
Powered by a 4-cylinder, water-cooled, exhaust turbocharged inline engine (model D 924 TI-E A2), it generates a gross power of 198 hp (148 kW) at 2000 rpm with peak torque at 1200 rpm. The hydraulic system includes a load-sensing variable axial piston pump delivering 60.8 gal/min (227 l/min), enabling quick dump, raise, and lower times of 2.3, 5.5, and 2.7 seconds respectively, operating under a relief valve setting of 4786 psi.
This machine runs on a stepless hydrostatic 2plus2 transmission with three forward and three reverse gears, achieving a maximum speed of 24.9 mph (39 kph) in both directions. Operating weight stands at 38,140 lbs (17,300 kg), with a static tipping weight near 30,700 lbs (13,925 kg). The tyres measure 23.5 R 25, providing a turning radius of 20.9 ft (6 m). It has ample fluid capacities for engine oil (5.5 gal), front axle/differential (13.5 gal), rear axle/differential (7.4 gal), hydraulic fluid (58.2 gal), and fuel (68.7 gal). Rear axle oscillation is 26° to ensure stability over uneven terrain. The system operates on 24 V electrical voltage and delivers 55 A alternator output. This loader is designed for high productivity and versatility in medium to heavy earthmoving applications.
