2007-2018 CATERPILLAR 993K WHEEL LOADER

Technical Description

The Caterpillar 993K is a high-performance large wheel loader engineered for heavy-duty mining and construction applications. Powered by a Cat C32 ACERT engine delivering a net power of 973 hp (726 kW) and gross power of 1,050 hp (783 kW), it ensures robust performance and reliability compliant with U.S. EPA Tier 2 standards. The machine weighs approximately 294,800 lbs (133,720 kg) and features a fixed front axle with 10° oscillation and a trunnion-type rear axle for enhanced stability and traction. The 993K is equipped with a versatile bucket system offering capacities from 13.1 to 31 cubic yards (10 to 24 m³), featuring a breakout force of 159,562 lbs (72,377 kg) and a bucket width of 16.6 ft (5 m) to handle large material volumes efficiently. Its hydraulic system utilizes three fully variable electro-hydraulic pumps with positive flow control, operating at relief valve settings up to 4,278 psi for lift/tilt and 5,000 psi for steering, enabling rapid cycle times—the dump, lower, raise, and rack back cycles combine for a total hydraulic cycle of 17.2 seconds. Dimensions include a height to cab top of 19.6 ft (6 m), ground clearance of 2 ft (1 m), and a wheelbase of 19.4 ft (6 m), with a turning radius of 36.1 ft (11 m), providing maneuverability in constrained areas. The transmission offers three forward and three reverse powershift gears, with speeds up to 13.6 mph (22 km/h) forward and 15 mph (24 km/h) reverse, ensuring efficient transport. Its operational design emphasizes durability, ease of service, and operator comfort, making the 993K a reliable solution for large-scale material handling and haulage operations.
