l  The hydraulic system with negative flow control function reached international advanced level to meet specific requirement and energy saving goal. Secondary overload valve and safety valve are placed on the main valve to protect circuit. When the loop pressure fall to the range of the setting value, the constant power control of the single pump works normally. The main oil circuit system can achieve negative flow control, when the host in no action (i.e., the main valve spool at neutral position) the engine almost no load, the main pump operate with about 60l/min flow output.

l  This machine uses open hydraulic system with total power variable high-pressure double pump double loop. The maximum working pressure is 34.3MPa, and the maximum flow 2x210l/min. Hydraulic oil from the fuel tank into the main pump, and the pressure oil supplied from the main pump via the main valve for winch, power head, traveling, slewing, etc., and through confluence to speed up the operation. The safety valve and overload valve of the main circuit system are placed on each main valve to protect the hydraulic circuit.

l  The double pump is supplied with oil by the sealed hydraulic tank and the capacity is 360L. The oil tank is equipped with a magnetic- paper combined return oil filter.

l  The machine electric system is a live, effective and flexible control system. The instrument with LED display and automatic backlight illumination, detects all kinds of pressure, temperature, oil level and give sound, light alarm; it also responsible for the engine, hydraulic pump, hydraulic control valve and the composite control of the whole machine, in order to detect and protect the engine, hydraulic system on good working conditions, thus ensuring the high reliability of the machine.

l  The machine adopts oil-water cooling technology with compact structure and better cooling efficiency. Large-capacity automatic heating air-conditioning system, three-dimensional air supply, fresh air circulation, fluoride-free environmental protection, automatic defrost, streamlined appearance of the cab provide a car-like working environment with shockproof noise, wide vision, safe and comfortable.
