Main technical characteristic of hydraulic material handler NK50-6
○ Turbo-charged after-cooled diesel engine: environment protecting, power saving, its satisfied the emission of Europe Standard Grade.Ⅲ
○ 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
○ Technique 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
○ Two shift travel speed to satisfied the moving requirement of the machine
○ Travel with multiplex action in line
○ Attachment strengthened of straight Boom 、 gooseneck Stick and sorts of work tools
○ Case shape structure, attachment designed by CAD and the casting-welding structure realizing the high strength structure.
○ Better reliability with hose and seal from Italy and Trelleborg cylinder seals
○ The Technique with disassembled undercarriage which is advanced to transport the machine quickly
○ The multi-function meters of detection of the various pressure ,temperature and oil level to have sound-light alarm
○ Cab is provided with large tri-dimensional ventilation, fresh air circulation, large capacity air condition without fluorine
○ The fixed cab elevation 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.
○ Automatically injecting the fuel
○ E xchanged Teeth
Following advanced systems can be equipped as option :
