Introduction of Used 2021 SEM 816D Crawler Bulldozer

This is a pre-owned SEM 816D medium crawler bulldozer manufactured in 2021. Inheriting Caterpillar’s proven technical system, it is a classic 160HP workhorse widely applied to site leveling, earthwork backfilling, road construction and mining operations. With reasonable working intensity, it remains in excellent working condition.

Overall Appearance

It retains Caterpillar’s classic yellow-and-black original factory paintwork, free of collision deformation or sheet metal repairs. The standard semi-U dozer blade features even wear, with ample remaining service life for the cutting edge and teeth. Undercarriage components including track chains, track rollers and carrier rollers show normal wear with no cracks or uneven abrasion. The radiator grille, side guards and boarding handrails are fully intact, presenting excellent exterior condition.

Engine

It is powered by a Weichai WP10 electronically controlled diesel engine with a rated power of 140kW, meeting China Stage III emission standards. The 9.7L large displacement delivers abundant torque reserve, ensuring stable and strong power output under heavy loads with outstanding fuel economy. The engine has no disassembly or overhaul history, running smoothly at idle without abnormal noise, leakage or oil burning issues. It enjoys high spare parts compatibility and low daily maintenance costs.

Transmission & Undercarriage

The drivetrain adopts Caterpillar’s third-generation dual-circuit electronically controlled hydrostatic technology, supporting stepless speed control and counter-rotation. Eliminating the traditional gearbox structure, it achieves higher transmission efficiency and lower maintenance costs, with a maximum drawbar pull of 280kN for flexible and efficient operation. The equalizer bar undercarriage delivers excellent impact resistance and adaptable ground pressure, easily handling various complex unpaved job sites.

Operability

The panoramic sealed cab offers wide visibility with an adjustable shock-absorbing seat. The single-lever control integrates travel and implement functions for light and precise handling, reducing operator fatigue during long shifts. The dashboard displays clear information, and the integrated fault self-diagnosis function facilitates daily maintenance.

Overall Condition

The machine has been regularly serviced strictly per official specifications. Its hydraulic and electrical systems operate stably without hidden faults or leakage, with reliable performance ready for immediate operation upon delivery. Backed by Caterpillar’s technical endorsement, SEM equipment features robust durability, easy spare parts access and strong value retention, making it a cost-effective choice for construction operations.
