Introduction of Used 2018 SEM 816 Wetland Crawler Bulldozer

This is a pre-owned SEM 816 wetland crawler bulldozer manufactured in 2018, with genuine 6,600 working hours and premium condition. As a classic medium-sized bulldozer from SEM under Caterpillar, it features a dedicated low-ground-pressure wetland design, widely applicable to swamp backfilling, site leveling, farmland reconstruction and soft earthwork, making it a cost-effective choice for soft, muddy working conditions.

Overall Appearance

It retains Caterpillar’s classic yellow-and-black factory original paintwork, free of collision deformation or sheet metal repairs. The standard straight tilting blade has even wear, with ample remaining service life for the cutting edge and teeth. The travel system is fitted with 42-track-link wide wetland tracks; undercarriage parts 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 WP10G190E314 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, strong power output under heavy loads with excellent fuel economy. The engine has no disassembly or overhaul history, running smoothly at idle without abnormal noise, oil leakage or oil burning issues. It enjoys high spare parts compatibility and low daily maintenance costs.

Transmission & Undercarriage

The drivetrain inherits Caterpillar’s third-generation dual-circuit electronically controlled hydrostatic technology, supporting stepless speed control and counter-rotation (spin turn). Eliminating the traditional torque converter and gearbox, it achieves higher transmission efficiency and lower maintenance costs, with a maximum drawbar pull of 280kN for outstanding working efficiency. The wide wetland tracks deliver extremely low ground pressure for excellent passability on soft, muddy terrain. The equalizer bar undercarriage has excellent impact resistance, easily handling complex unpaved job sites.

Operability

The panoramic cab offers wide visibility with an adjustable shock-absorbing seat. The single-lever electronically controlled travel control paired with pilot-operated implement control ensures light and precise handling, with cruise control to reduce 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 fully verified performance — ready for immediate operation upon delivery. Backed by Caterpillar’s technical system, SEM equipment features robust durability, easy spare parts access and strong value retention, making it a premium choice for wetland earthwork operations.
