* Grand automatic excessive pressure anti elimination function, makes your operation more relaxed.  

*The entire hydraulic pressure reverse control system is adopted : pumping, The S tube assignment commutation

movement does not need the electrical signal participation; small commutation impact; low noise, obviously improving

 the hydraulic pump and hydraulic valve service life.

*The entire hydraulic pressure reverse control system omits the middle link which the electrical signal controls, enhancing

the complete equipment system's reliability greatly.  

*Adopting concentrating valve board: concentrating the primary system on a hydraulic valve plate, and reducing cross

connection lines, so that the system is more closely, and meanwhile the opportunities of oil leakage can be reduced.

*Adopting concentrated lubrication system: reinforcing distribution system supply oil to each lubricating points and feeding

 oil timed and quantitative which can help to save both equipment maintenance time and lubricant dosage
