GHP3017E Engineering Concrete Wet Spray Trolley

  • main motor power:55KW

  • injection displacement:30m³

  • Vehicle size:7890x2680x3200mm

  • Curb weight:17000KG

Applied range:

The equipment has a multi-joint degree of freedom controlled manipulator, with large operating coverage and no blind spots, which can meet the construction needs of various cross-section tunnels and improve construction efficiency.


Walking system

It adopts original Dana steering drive axle, hydrostatic transmission, adjustable high and low speed, automatic driving experience, and more convenient handling. Four-wheel drive, four-wheel steering, stable and reliable performance.

Electric control system

The special controller for construction machinery is adopted, which has better dust resistance and water resistance; the failure rate is extremely low, and it can adapt to harsh environments. The panel adopts a lower limit design to prevent misoperation.

Concrete delivery pipe

The conveying pipe adopts a large diameter pipe, which reduces the wear of concrete to the pipe, prolongs the service life of the pipe, and has strong anti-blocking ability.

Emergency system

When the power grid is cut off, the emergency system can be activated, and the chassis engine can be used as the power to carry out all functions of emergency operation.
