Main technical characteristic of hydraulic material handler NKD50-5
○ In addition to Air-cooled diesel engine, electromotor can be equipped to the power unit as well (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.).
○ Control system by total power for double pumps & circuits with reasonably distributing and using the power
○ The confluence of double pump, raising the working efficiency
○ The frequent-open swing, the walking brake
○ Independent oil-cooling system
○ Choosing structures type 、 dimension 、 work scope and grab capacity of strengthened work plants according to customers’ requirements
○ Better reliability with hose and seal from Italy and cylinder seals from Italy
○ 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.
○ 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.
○ E xchanged Teeth
Following advanced systems can be equipped as option :
□ Hydraulic lifting cab
□ Electro-Magnets equipment
□ Electronic weighing system
□ Monitoring system with displayer
□ Automatic central lubricating system
