Product Description

QKSP-20C Short Concrete Wet Spraying Bolter Machine  

FEATURES OF PRODUCTS:
1. The use of variable distance outriggers can improve the stability of vehicle operation and prevent the vehicle from overturning.
2. Full computer control system and large full-color display screen are adopted. The system has self diagnosis ability, which can effectively improve the reliability of equipment operation and fault finding.
3. The front and rear drive axles adopts engineering axles with four-wheel drive four-wheel steering function, which can be used for front wheel steering, four-wheel steering, crab steering and other steering modes.
4. The chassis adopts high-strength self-made engineering chassis with strong bearing capacity, passing capacity and climbing capacity.
5. The real dual power system is adopted, and wet spraying can be carried out even without 380V power supply.
6. The key components of the whole machine, such as hydraulic main pump, electrical controller, manipulator oil cylinder, main valve group, are all imported components, effectively improving the reliability of the equipment.
7.The international advanced hydrostatic drive system is adopted for the power system which can effectively improve the walking stability of the vehicle.
