Technical characteristics power system

Driving environment

High-efficiency shock-absorbing seat to maximize the comfort of operation, and the operator will not be tired after long-term work The cab is equipped with air conditioning as standard, with an overall sealed vibration reduction system, using double-layer sealing, sound-absorbing sponge, low vibration and noise, and the noise at the driver's ear can be as low as 80 decibels; Adopt intelligent display and control terminal integrated instrument, fault online detection and alarm, provide a richer humanized driving experience, and a comfortable and safe driving environment;

Product Display

Easy maintenance

The electro-hydraulic control power shift transmission produced by ZF technology has 6 front and 3 rear gears. The best gear can be selected according to the working conditions to achieve the best combination of walking and operation; Three-stage integral drive axle, built-in imported no-spin automatic anti-skid differential, stable and reliable transmission; The balance box is driven by a heavy-duty roller chain, and the machine has better passability and terrain adaptability, which can meet normal construction operations under special road conditions, with stable power output and strong driving force.

Operational performance

The external gear working device with independent patent technology has large transmission torque and strong resistance to external impact; The blade with a larger angle adjustment range (44°-91°) improves the material control ability and is especially useful when dealing with dry materials and clay, which can significantly improve the operation efficiency of the grader; The connecting rod type swing frame is adopted, which has strong resistance to external impact and is suitable for working conditions with large workload and harsh working environment.
