Introduction of Used 2019 Caterpillar 336D2 Hydraulic Excavator

This is a pre-owned Caterpillar 336D2 36-ton hydraulic crawler excavator manufactured in 2019. As a classic heavy-duty model in CAT’s D2 series, it is built for high-intensity rock, mining and infrastructure earthmoving scenarios. Renowned for its proven reliability and extremely low failure rate, it is a benchmark large excavator in the global construction market, with well-regulated operation history and excellent overall condition.

Overall Appearance

It retains Caterpillar’s iconic yellow original factory paintwork, free of collision deformation or sheet metal repairs. The boom and arm are structurally intact with no welding, cracks or reinforcement. The standard 1.88m³ wear-resistant bucket features even wear with ample remaining service life for the bucket teeth. Undercarriage components including track chains, track rollers and carrier rollers show normal wear with no cracks or uneven abrasion. Body guards, boarding handrails and radiator grilles are fully intact, presenting excellent exterior condition.

Engine

It is powered by an original Cat C9 ACERT inline 6-cylinder diesel engine with a rated power of 208kW and 8.8L displacement, meeting China Stage III emission standards. Adopting ACERT precision fuel injection technology, it delivers outstanding combustion efficiency and ample torque reserve, with stable, strong power output under heavy loads and better comprehensive fuel consumption than peer models. The engine has no disassembly or overhaul history, running smoothly at idle without abnormal noise, with clean oil circuits free of leakage and responsive throttle performance.

Hydraulic & Undercarriage System

The hydraulic system adopts a dual-main-pump negative flow control system, with a maximum flow of 281L/min per pump. Dual-pump confluence enables fast and smooth working cycles without jamming. Both swing and travel are driven by high-speed hydraulic motors paired with planetary reduction final drives, delivering high transmission efficiency and reliability, with a maximum drawbar pull of 300kN and 70% gradeability. The heavy-duty X-type lower frame features excellent torsion resistance, and the standard 600mm track plates provide reasonable ground pressure, easily handling complex unpaved conditions such as mining sites and muddy terrain.

Operability

The fully sealed shock-absorbing cab offers spacious interior with a multi-angle adjustable suspension seat for high operating comfort. The pilot control levers are light and precise with excellent maneuverability. The high-definition dashboard displays clear information, and the integrated fault self-diagnosis function facilitates daily maintenance.

Overall Condition

With reasonable genuine working hours, the machine has been regularly serviced strictly per Caterpillar’s official specifications. Its hydraulic and electrical systems operate stably without hidden faults or leakage, with fully verified performance — ready for immediate operation upon delivery. With large global market presence, comprehensive spare parts supply and strong value retention, Caterpillar equipment is a cost-effective premium choice for heavy-duty construction operations.
