- Using the United States Cummins produced QSL-9 series of electric control in the cold engine, is characterized by high power weight ratio, low noise, stable performance in a variety of speed, to Euro Ⅲ emission standards. The power unit directly drives the dual power piston pump with two axial piston pumps, in which the large displacement axial piston pump is used for the rotary system and the small displacement axial piston pump is used for all cylinders. 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 composite action. The main pump is equipped with the limit load control and the micro speed control. The intelligent power distribution between the engine and the hydraulic system is realized by the CAN bus. It effectively protects the engine from overloading and reduces the fuel consumption. Moreover, the variable pump and the variable motor system are adopted. Load sensing control, greatly improving the speed performance and vehicle smoothness. Control system uses hydraulic pilot control, the operation reflects the sensitivity to ensure that all the smooth action. It is driven by a hydraulic variable motor through a built-in reducer. The balancing valve is installed on the motor. The gear reducer is equipped with a hydraulic brake release 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. The slewing system is a closed system, driven by a hydraulic motor through a reducer, the gear 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 overturned, main arm luffing angle limit, main arm anti-dumping device, wire rope down three laps protection.
