imported LINDE high quality hydraulic elements are used in the hydraulic system.Control system adopt multi-load pilot control main pump displacement,it is high efficient and economic .Elecyril-hydraulic proportional control technology ensure that mechanisms action is synchronizing and best match under the different work conditions.

   By means of pilot proportional value control the pilot hudraulic circuit to operate the working device and control replacement of main pump,the swivel releasing,changes the rotary speed of main winch braking and power head.The system is high efficient,micro-adjustable and operating easy.

Radiating can be applied automatically by an independent cooling system when oil temperature is over rated temperature, ensure that the hydraulic system is working normally.
