GHP20A Truck-mounted wet shotcrete machine

GHP20A Truck-mounted wet shotcrete machine adopts double pump and double circuit hydraulic system, which has better performance and more stability. Automobile chassis, flexible movement, stable performance, fast transition.

  • Driving way:Hydraulic drive

  • Production capacity:20m³/h

  • Concrete outlet pressure:63bar

  • Hopper volume:0.3m³


With dual pump and dual circuit hydraulic system to make machine more superior and more stable

Using double pumps hydraulic system to reduce the residence time of slave cylinder piston and weaken the pulse, operating reliably with non-interfering.

Excellent equipment structure

Stable performance, rapid transition

Increasing air pressure at the exit of dual spray nozzles for the concrete of poor fluidity

Increasing air pressure at the exit of dual spray nozzles for the concrete of poor fluidity.

Low air consumption,small rebound,high work efficiency

With low air consumption,small rebound, less labor, less material consumption to improve work efficiency and reduce construction cost.

Adding accelerator filter, convenient to maintain

Adding accelerator filter, more confidence in maintenance.

Automobile chassis,moving flexibly

Using automobile chassis to make moving operation more flexible.

Single spray nozzle to add air pressure, improve spraying efficiency greatly

Using single spray nozzle to increase air pressure, and the maximum production capacity can reach 20m³/h.

Discharge port is connected to dual spray nozzles directly

Reduce the delivery distance from concrete to spray-head, making spraying more smooth and stable.

Reduce dust pollution, improve construction environment

Reduce dust pollution effectively, improve construction environment greatly.

Equipped with storage platform, easy to deliver goods

Equipped with storage platform, easy to deliver goods.
