Product Description

The mining motor grader GR3003 is mainly used for ground leveling, ditching, slope scraping, bulldozing, scarification, snow removal for large areas such as highway, airports, farmlands etc. It is the necessary construction machinery for national defense construction, mine construction, urban and rural road construction and water conservancy construction, farmland improvement and so on.

1. The friction-disc worm gearbox with overload protection is developed for the mining heavy load condition, which can slip automatically and protect the safety of the machine and personal.

2. Load sensing hydraulic system is equipped with variable piston pump and load sensing multi-way valve, in order to improve operation comfort, the pilot independent electrical proportional valve, the main directional valve and relief valve are proportional valves.

3. The service brake is a double-loop hydraulic braking system.

4. For serious environment condition, to analyze the matching analysis of the cooling system, conduct flow field analysis to power compartment machine, reasonable layout of the cooling holes, seal the clearance around the radiator, form the"chimney effect" of air duct design, reduce the hot air vortex. At the same time, the optimized hood design, spray anti-vertigo paint, beautiful shape.

5. The same time using ROPS&FOPS cabin to meet ISO standard. Equipped with air conditioning, adjustable suspension seat, equipped with wipers and defrosting vents to improve the comfort of operation.

6. Spacious cabin design, three-dimensional air duct, good driving experience. Double handle operation can be selected on the handle operation, reducing the labor intensity by about 80%.
