CATERPILLAR 986H WHEEL LOADER

Technical Description

The Caterpillar 986H is a robust, heavy-duty wheel loader designed for high productivity in construction and mining applications. Powered by a Cat C15 ACERT engine, it delivers a net power output of 409 hp (305 kW) and peak torque of 1,711 lb-ft (2,320 Nm) at 1,200 rpm, ensuring strong performance and torque rise of 37%. The engine is a 6-cylinder turbocharged unit with a displacement of 15.2 liters and a bore/stroke of 5.4 in (137 mm) / 6.75 in (171.5 mm). The loader’s operating weight ranges around 93,000 to 106,700 lbs (42,119 to 48,430 kg) depending on configuration. The 986H features a rated bucket capacity between 7 to 13.5 cubic yards (5 to 10 m³), with dump clearance up to approximately 11.1 ft (3.4 m) in the high lift variant. It offers precise hydraulic control with a load-sense lift/tilt system powered by two 110 cc variable displacement pumps, delivering a maximum flow of 123 gallons per minute (466 L/min) at 2,165 rpm. Hydraulic cycle times optimize efficiency with dump and raise operations completed in approximately 3.5 to 9 seconds. Axle design includes a fixed front axle with 12.5° oscillation and a trunnion-mounted rear axle, optimizing stability and ride comfort. The transmission is a Cat planetary power shift with multiple forward/reverse speeds, reaching up to 24 mph (39 km/h). The hydraulic steering system also features a variable displacement piston pump with a 70° total steering angle and 4000 psi cut-off pressure. Service capacities include a fuel tank up to 159 gallons (602 L) and cooling system capacity of 24 gallons (91 L), supporting long operational periods. Overall, the CAT 986H combines power, durability, and hydraulic efficiency for demanding material handling tasks.
