The chassis drive system adopts a mining articulated chassis, powered by an explosion-proof diesel engine. The drive system adopts static hydraulic transmission, four-wheel oil immersed, spring brake, and hydraulic release wet brake, with stable performance Fixed, high safety factor;

The pumping system can switch between explosion-proof motor and diesel engine dual power drive, and the control system adopts two modes: wireless remote control and local control; In motor operation mode, the remote control can be used to perform short distance walking of the vehicle; The working mode of the motor requires the use of underground 660V/1140V power supply, with zero pollution in the working environment;

The spraying system adopts remote control, and the conveying amount of concrete and accelerator can be adjusted, achieving small rebound, high efficiency, and low labor intensity& Nbsp;

The use of wet concrete spraying technology has the advantages of low dust, low rebound, and high concrete strength after wall hardening;

The key components are imported, with high reliability.
