LETOURNEAU L1350 WHEEL LOADER

Technical Description

The Letourneau L1350 wheel loader is a heavy-duty machine designed for large-scale mining and material handling applications. It features a turbocharged QSK 45 engine delivering 1600 hp at 1900 rpm with 12 cylinders and a displacement of 2746 cu in. The loader's bucket capacity is 28.1 cu yd (heaped) with a breakout force of 220,000 lbs, a bucket width of 20.6 ft, and a dump clearance at max raise of 21.1 ft. The machine measures 55.5 ft in length with bucket on ground, 19.8 ft in height to the top of the cab, and 19 ft in width over tires, with a wheelbase of 21.3 ft and ground clearance of 2.5 ft. Its operating weight is approximately 400,000 lbs. The hydraulic system uses a piston pump with a flow capacity of 374.9 gal/min and is set to a relief valve pressure of 3300 psi, offering dump, raise, and lower times of 3, 13, and 5 seconds respectively. The transmission is infinitely variable, allowing forward and reverse speeds up to 10.1 mph. The machine carries a fuel capacity of nearly 925 gallons and an overall hydraulic fluid capacity of 374.9 gallons. Axle fluid capacities total 72 gallons combined, with rear axle oscillation at 22°, supporting rough terrain operation. The L1350 High Lift variant offers similar power with a reduced bucket capacity of 26.1 cu yd and increased dump clearance and hinge pin height for enhanced reach and loading height, weighing around 405,000 lbs. Tire size for both models is 50/80-57 68PR L-4.
