CATERPILLAR 336E CRAWLER EXCAVATOR

Technical Description

The Caterpillar 336E is a large hydraulic excavator engineered for high productivity and fuel efficiency. It is powered by a Cat® C9.3 ATAAC diesel engine delivering a net power output of 316 hp (236 kW), compliant with EPA Tier 4 Interim emission standards. The machine weighs approximately 80,617 lbs (36,570 kg), balancing robust structural durability with mobility. It features an operating weight range up to about 86,796 lbs (39,370 kg) depending on configuration. The 336E offers an impressive maximum digging depth of 24.6 ft (7.5 m) and a maximum digging reach of 36.2 ft (11 m), suitable for deep and extensive excavation tasks. The boom length is typically around 6.5 m (21'4"), with stick options from 3.2 m to 3.9 m (10'6" to 12'10"), designed for versatility across various job site conditions. Bucket capacities can reach approximately 2.28 m³, supporting effective material handling. The hydraulic system operates at pressures up to 35,000 kPa for equipment and travel, with a main system flow capacity of around 570 L/min, enabling powerful and responsive hydraulic performance. Features like an electric boom regeneration valve and stick regeneration circuit improve fuel efficiency by recycling hydraulic energy during certain operations. The excavator’s maximum travel speed is approximately 4.9 km/h (3 mph), with a drawbar pull of 295 kN, ensuring strong traction and mobility. Additional technical highlights include a fuel tank capacity of 620 L, cooling system capacity of 56 L, and hydraulic tank volume of 175 L. The machine has a swing speed of about 9.2 rpm with 109 kN·m of swing torque, providing smooth, controllable 360-degree motion. Operator noise is rated at 72 dB(A). Overall, the Cat 336E integrates fuel-efficient technology with powerful hydraulic capability, making it suitable for a wide range of heavy excavation applications.
