Mining Excavator (460)

Product Description

Mining Excavator (460), hydraulic excavator, excavator, ore excavator, electric excavator, mine equipment.

Main technical characteristic of hydraulic excavator D460-6

*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.
