SEM650 Wheel loader

Main feature:

1, Engine: be reoptimized and rematched, improved efficiency and performance, improved cold start capacity.

2, Cooling: Designed by CRDC (Caterpillar China Research & Design Center), the cooling system brings end results of optimal cooling efficiency, increased fuel efficiency, less radiator plugging even under extreme hot temperature or dusty work environment.

3, Transmission: Countershaft design; advanced structure, high transmission efficiency; durable, ease of service and numerous shifts allow high travel speed; two modes available for multiple operation, one for material handling and one for travel; refined for heavy duty application.

4, Axle: Large module gears, tuned for heavy duty with durability

5, Cab: Improved operator comfort and visibility; Reduced in cab noise, meet GB standard, Reliability improved; integrated FOPs/ROPs cab is available.

6, Electrical: Large capacity Delphi battery; High quality electrical components.

7, Structure: Finite Element Analysis (FEA) design, refined for heavy duty application.

8, Hydraulic: VALVE [CCMC (Caterpillar China Machinery Component) components; Single lever, joystick controlling (optional)]

            HOSE [CCMC hose, improved strength and reliability, optimized hose and tube routing]
