Equipment Overview
The Cat 993 is a large mining-class wheel loader introduced in 2008 and built for maximum availability through multiple lifecycles, part of Caterpillar’s large wheel loader range with bucket sizes matched to Cat truck bed capacities. It delivers 719 kW (964 hp) net and a 133,668 kg operating weight, suited to large-scale mining and material handling with a 27.2 t standard-lift payload.
Power comes from a Cat C32B engine delivering 5,470 N·m of peak torque and a 33% torque rise for high lugging force, meeting U.S. EPA Tier 4 Final/Tier 2 Equivalent emission standards and driving a Cat Planetary Powershift transmission (3F/3R) designed specifically for mining applications. An Impeller Clutch Torque Converter with Rimpull Control System improves rimpull and reduces tyre slippage, and a Positive Flow Control hydraulic system with variable piston pumps delivers fast, consistent loading cycles.
