Audited Supplier It's equipped with single-stage single-phase three-element torque converter and fixed shaft powershifts transmission for power transmission, featuring good power matching and stable motions. The split structures ease the repairs and maintenances. The transmission includes four forward gears and four reverse gears. This product is especially suitable for long-distance heavy-load mining operations and features more powerful operations and faster motions.
The 3,200mm wheelbase guarantees both outstanding site adaptability and flexibility and powerful operation stability to handle the common heavy-duty mine operations (such as stripping) with ease.
By minimizing the torque difference between the front and rear drive shafts at turns, it prevents the slip difference between the front and rear wheels and ensures the coincided wheel paths between the front and rear wheels to improve the service life of tires and trafficability of machine and reduce the energy loss. The articulated structure of tapered roller bearings is adopted for front and rear frames, featuring reliable operations and easy maintenances.
With the adoption of finite element analysis optimization and the utilization of plate structure and automatic robot welding, the structural parts of the main machine feature high resistance against load and distortion, high firmness and compactness, and good stability.
The imported high-pressure hoses manufactured by the non-skiving process as per DIN standard are adopted for all critical locations and the 24o taper thread and sealing of two O-rings guarantee high resistance against heat and high pressure, complete air-tightness against leakage, and reliable performance.
With the 12o vertical swing design for swing frame, the loader can ensure more effective ground touch while driving on rugged roads, featuring higher adhesion and better stability and trafficability.
Multiple working devices, including timber grab, bale grab, coal bucket, side dumping bucket, and quartering hammer, are at your choice.
