○ Three phase-asynchronous electromotor, the only technology in China for hydraulic material handler powered by electricity, it is of benefit to environment protecting, power saving, easy service & maintenance, and low operating cost.
○ New dual electric brush and collector ring bring longer lifetime.
○ Control with constant power of single pump, crossover power of two pumps for reasonably distributing and using the power
○ Starting with zero displacement so as to reduce the moment of resistance at starting
○ T echnique with pressure cut to protect hydraulic system and reduce the system heat
○ Secondary overloading for swing and normal closed brake for swing and travel ensure smoothly brake
○ Integrated oil& water cooler with compact conformation
○ The working attachment realized automatic level crowding with bucket to increase the bucket filling factor
○ Attachment designed by CAD, case shape and casting-welding structure realizing the high strength
○ Automatic central lubricating system to save daily lubrication
○ Multi-function meters show automatic illumination and detection of the various pressure ,temperature and oil level to have sound-light alarm
○ Better reliability with Parker hose &seals and Trelleborg cylinder seals
○ The Technique with disassembled undercarriage which is advanced to transport the machine quickly
○ Cab is provided with large tri-dimensional ventilation, fresh air circulation, large capacity air condition without fluorine
○ The operator’s cab with the wide vision field and the streamlined appearance, matching the decoration and function with human nature, and offering the working environment in a car.
