2006-2010 LIEBHERR L550 2PLUS2 WHEEL LOADER

Technical Description

The Liebherr L550 2PLUS2 wheel loader is a versatile articulated machine designed for efficient material handling with a bucket capacity of 4.2 cubic yards (3 m³) and an 8.9 ft (2 m) bucket width. It offers a dump clearance of 9.5 ft (3 m) at maximum lift and operates with a ground clearance of 1.8 ft (0 m), a total machine height of 11.1 ft (3 m), and a hinge pin height of 12.9 ft (4 m). The loader’s overall length with the bucket on the ground is 27 ft (8 m), and it has a wheelbase of 10.8 ft (3 m). Powered by a turbocharged Liebherr D 934 S A6 engine, the L550 delivers 174.4 hp (130 kW) at 2000 rpm with four cylinders, achieving maximum torque at 1300 rpm. It features a hydrostatic transmission with three forward and reverse gears, allowing a maximum travel speed of 24.9 mph (39 kph) in both directions. The hydraulic system incorporates a load-sensing swash plate pump with a flow capacity of 76.7 gal/min (288 l/min), delivering quick cycle times with 5.5 seconds for raise, 2.3 seconds for dump, and 2.7 seconds for lowering. Operating weight is approximately 36,431 lbs (16,525 kg), with a static tipping weight of 29,112 lbs (13,205 kg). It runs on Michelin 23.5R25 tires and has a rear axle oscillation of 26°. Fluid capacities include 79.3 gallons fuel, 63.5 gallons hydraulic fluid, 11.9 gallons cooling system, and 8.2 gallons of engine oil. The alternator supplies 80 A at 24 V operating voltage, supporting the machine’s robust electrical system. This configuration ensures durability, maneuverability, and power suited for demanding construction and material handling tasks.
