1994-2014 HYUNDAI HL740-9 WHEEL LOADER

Technical Description

The Hyundai HL740-9 is a robust wheel loader engineered for efficiency and durability in heavy-duty applications. Powered by a turbocharged Cummins QSB6.7 6-cylinder engine, it delivers a gross power of 145 hp (108 kW) at 2100 rpm, with net power at 143 hp (107 kW) and maximum torque at 1400 rpm. The loader’s operating weight is approximately 26,460 lbs (12,000 kg), providing stability and strength during operation. Its bucket capacity is rated at 3.1 cubic yards (2.37 m³) heaped and 2.7 cubic yards (2 m³) struck. The HL740-9 features a variable axial piston pump hydraulic system with a flow capacity of 41 gal/min (155 l/min), enabling fast cycle times: 5.5 seconds to raise, 3 seconds to lower, and 1.1 seconds to dump. The loader’s maximum dump clearance at full lift is 9.2 ft (3 m), with a maximum hinge pin height of 12.6 ft (3.85 m) and a reach of 3.4 ft (1 m) at max lift and dump. Its dimensions include a length of 24.3 ft (7 m), width of 8.6 ft (2.6 m), and height to the top of the cab at 10.7 ft (3.26 m), with ground clearance of 1.4 ft (0.42 m). Transmission is a powershift type with 4 forward and 3 reverse gears, allowing a max forward speed of 24.3 mph (39 kph) and reverse speed of 15.6 mph (24 kph). The wheel loader uses 20.5-25 tires and includes robust axles with 24° rear axle oscillation for excellent maneuverability. Fuel capacity is 58.2 gallons (220 liters). The advanced hydraulic and transmission systems combined with ergonomic cab controls and onboard diagnostics optimize performance, reliability, and operator comfort.
