Technical Description

The Hyundai HL780XTD-9 wheel loader features a turbocharged QSM11 engine delivering 344 hp (257 kW) at 2000 rpm with 6 cylinders, providing robust power and torque measured at 1400 rpm. It offers a bucket capacity of 7.1 cubic yards heaped (5 m³) and 6.1 cubic yards struck, with an 11.4 ft (3 m) bucket width. The machine's dump clearance at maximum raise reaches 12.1 ft (4 m), and the hinge pin max height is 16.2 ft (5 m). Dimensions include a wheelbase of 12.2 ft (4 m), ground clearance of 1.7 ft (0.5 m), and overall length with the bucket on the ground of 33.1 ft (10 m). It rides on 29.5-25 tires with a width over tires of 10.6 ft (3 m) and a top cab height of 12.7 ft (4 m). The hydraulic system utilizes a variable axial piston pump with a flow capacity of 111 gallons per minute (420 l/min), offering efficient cycle times: raise in 6.1 seconds, lower in 4.1 seconds, and dump in 1.4 seconds. The loader’s operating weight is approximately 67,900 lbs (30,800 kg) with a static tipping weight of 47,400 lbs (21,500 kg). Fuel capacity is 118.9 gallons (447 liters), with hydraulic fluid capacity at 61.9 gallons (231 liters). Transmission is a powershift type with 4 forward and 3 reverse gears, allowing a max forward speed of 22.7 mph (35 kph) and max reverse speed of 15.6 mph (24 kph). The electrical system runs at 24 V with a 70 A alternator. Rear axle oscillation is 26°, supporting operational stability on rough terrain.
