Product Description

SEM 655D wheel loader is a purpose-built heavy-duty machine engineered for high productivity in quarrying, mining, port operations and large infrastructure projects. With a 5,000 kg rated payload and bucket options from 2.7 to 4.5 m³, this model balances high-volume handling with fuel-conscious operation. Built on a robust frame and paired with either a Weichai WD10G or Cummins 6LT9.3 engine, the unit is optimized for sustained performance under demanding conditions.

• High breakout force: 168 kN breakout force delivers confident digging and quick fill cycles for heavy, compact materials.
• Twin-pump hydraulic system: Merging flow design reduces cycle times and improves simultaneous implement functions for faster truck loading.

• Efficient driveline: Optimized transmission and drivetrain yield excellent traction and stable high-speed travel on site.

The SEM wheel loader heavy duty architecture focuses on long service life. Heavy-duty axles and a reinforced frame, validated through FEA and OMSA analysis, ensure structural integrity in continuous, heavy-load applications. A high-performance cooling package keeps operating temperatures in check even at ambient temperatures up to 50 °C, preserving component life and reducing unplanned downtime.

Operators can select between the Weichai WD10G and Cummins 6LT9.3 engines to match fleet preferences for torque, fuel consumption and service networks. Integrated hydraulic-transmission calibration minimizes energy loss and lowers operating costs without compromising cycle speed or breakout capability.

Cab design emphasizes visibility, ergonomics and reduced operator fatigue. A spacious cabin with an adjustable suspension seat, joystick controls and well-arranged monitoring instruments supports accurate, efficient work over long shifts. Built-in safety features include a backup alarm, three-point access, and industry-standard ergonomic layouts to reduce risk during routine operations.
