(1) the engine using imported from Japan Mitsubishi hibiscus or Isuzu engine, adapted to high temperature and low temperature (-30 ℃ +50 ℃), the intake system using air pre filter.
The two engines for the 2 phase of emission, it has the advantages of reliable performance, high torque, low fuel consumption, low noise, low emission characteristics.
(2) hydraulic system with energy-saving control, can give full play to, the engine power, reduce the hydraulic loss.

The main hydraulic components selection of well-known products in the world. A full set of imported Parker original pipeline, joint, reliable negative flow hydraulic system, truly achieve the operating performance of a combined machine.
Hydraulic pump with negative flow control and constant power control mode, the engine output power and the main pump absorption unified power, save fuel consumption and give full play to the use of the machine performance and.

The main control valve with integrated within the system, boom, bucket rod confluence valve; boom, bucket rod retaining valve; straight travel valve; walking booster valve, so that the individual action performance is more secure, reliable, compound action more coordinated, steady.

All hydraulic lines and connections with American Parker company products, elastic sealing, no leakage.
The walking mechanism of high reliability, large traction force, strong climbing ability. Variable speed running. The grounding than the small, good stability, can be used in harsh conditions.
