HYUNDAI HL780XTD-3A WHEEL LOADER

Technical Description

The Hyundai HL780XTD-3A Wheel Loader is a heavy-duty machine designed for high-performance material handling and construction applications. It features a powerful Cummins QSM11 turbocharged 6-cylinder engine delivering 335 hp (250 kW) gross power and 320 hp (239 kW) net power at 2100 rpm, with peak torque of 1257 lb-ft (1704 Nm) at 1400 rpm. The loader weighs approximately 65,036 lbs (29,500 kg) with an operating voltage of 24V. Its robust hydraulic system has an open-centered, tandem circuit design with a pump flow capacity of 125 gal/min (473 l/min) and a relief valve set at 2990 psi, enabling rapid bucket operations with a dump time of 1.3 seconds, lower time of 3.5 seconds, and raise time of 6.4 seconds. The loader’s bucket has a breakout force of 53,700 lbs (24,358 kg) and a heaped capacity of 6.7 cubic yards (5 cubic meters), with a struck capacity of 5.7 cubic yards (4 cubic meters) and a width of 11.4 ft (3 m). Key dimensional specs include a wheelbase of 12.2 ft (4 m), dump clearance at max raise of 12.2 ft (4 m), hinge pin max height of 16.1 ft (5 m), and overall length with bucket on ground of 32 ft (10 m). Ground clearance is 1.6 ft (0.5 m), and tire size is 29.5-25 22 PR L3. Transmission is a full automatic power shift with four forward and three reverse gears, offering max speeds of 21.6 mph forward and 14.5 mph reverse. The machine holds 124.2 gallons (469 l) of fuel, 62.1 gallons (235 l) of hydraulic fluid, and features rear axle oscillation of 26 degrees for enhanced stability on uneven terrain. This combination of power, capacity, and precise hydraulic control makes the HL780XTD-3A a versatile loader for demanding construction and mining tasks.
