More energy-conservation and environmental protection
Imported engine with original packing has features of powerful force and high efficiency. Low noise and low emission can greatly reduce the pollution to the environment. Compared with other brands of the same level, it has greater digging force, rotary force, rotary force and traction force, which can ensure that the machine can work quickly and efficiently. It can meet all the application requirements. Blending with proven, sturdy and durable parts and delicate manufacturing process, higher reliability and efficiency can be achieved.

More efficient return
By use of mature and reliable negative flow control system, the flow distribution is provided by multi-port valve to all acting cylinders through the three pump converging, whereby the powerful digging ability and excellent working performance are maintained.

High quality integrated electric system, with higher indicator and electric centralized control, the design is more concise and the system is more reliable.

More reliable and durable
With boom and arm reinforced and key parts adopted with integration steel casting.Through structural optimization, stress concentration is reduced to ensure equipment reli- ability under severe conditions.

Standard heavy-load rock bucket,adopting the high strength steel and with cutting parts reinforced,is sturdy and durable enough to prolong the service life greatly.
