- Using the design of high integration, the use of good economy, and small size, light weight Dongfeng Cummins famous brand diesel engine. The power unit directly drives the total power variable plunger dual pump with a triple gear pump, in which the large displacement gear pump is provided with a separate rotary system, one small displacement gear pump for the control system and the other for all cylinders , Variable plunger double pump for left and right walking, main and auxiliary winch and main arm luffing system, the formation of various independent systems, to achieve compound action, by changing the main pump variable swing angle can achieve micro-motion. Control system uses hydraulic pilot control, the operation reflects the sensitivity to ensure that all the smooth action. Hydraulic oil using aluminum plate-finned air cooler, heat transfer efficiency. The hydraulic motor is driven by a built-in reducer. The balancing valve is installed on the motor. The gear reducer has a hydraulic release normally closed disc type maintenance-free brake and a pawl locking device to make the braking performance more reliable. Uses the broken line rope groove reel and the high quality does not revolve the steel wire rope. Driven by the hydraulic motor through the reducer, reducer with a hydraulic release of the normally closed chip maintenance-free brake, braking performance and reliable. By foot pedal proportional valve release the brake, so that the rotation is more stable, but also to achieve free slip. Fully enclosed cab, wide field of vision, adjustable seats, air conditioning, hydraulic pilot proportional control handle, easy to operate. Automatic torque limiter, automatic fault diagnosis device with display and alarm function, hook anti-roll, the main arm luffing angle limit, the main arm anti-dumping device.
