HYUNDAI HL757-9 WHEEL LOADERS

Technical Description

The Hyundai HL757-9 is a robust wheel loader designed for high productivity and efficiency in heavy-duty material handling. It is powered by a turbocharged Cummins QSB6.7 engine delivering 173 hp (129 kW) gross and 170 hp (127 kW) net at 2100 rpm, with maximum torque rated at approximately 600 lb-ft (83 kg·m) at 1400 rpm. The machine features a powershift transmission with 4 forward and 3 reverse gears, enabling a maximum travel speed of 23.5 mph (37 kph) forward and 15.1 mph (24 kph) in reverse. Operating weight is approximately 32,000 lbs (14,515 kg), with a wheelbase of 10.1 ft (3 m) and overall length of 24.9 ft (7 m). The loader's bucket boasts a heaped capacity of 3.6 cubic yards (2.8 m³) and a struck capacity of 3.2 cubic yards (2 m³), supported with a dump clearance at max raise of 9.4 ft (3 m) and a hinge pin max height of 12.9 ft (4 m). Ground clearance stands at 1.4 ft (0.41 m), and the width over tires is 9 ft (3 m). The hydraulic system uses a variable axial piston pump with a flow rate of 48.9 gal/min (182 l/min), enabling lift, dump, and lower cycle times of 5.9 sec, 1.1 sec, and 3.8 sec respectively. It has a 24 V electrical system with a 70 A alternator. Fuel capacity is 77.7 gallons (294 liters) supported by fluid capacities including 56.8 gallons (212 liters) for hydraulics and 9.3 gallons (34 liters) for cooling. Additional features include rear axle oscillation of 26°, self-adjusting wet disc brakes, limited slip differentials on front and rear axles, and a cab height of 10.9 ft (3.3 m), optimized for operator comfort and visibility. This model combines durability, reliability, and advanced hydraulics for smooth, productive operation in demanding construction and loading applications.
