Performance Features

1、High work efficiency, the output per hour can reach 21m3

2、The feeding hopper works with the lifting hopper coordinately and synchronously, realizing continuous feeding

3、The dry-mix shotcrete machine can slide easily in the track, and the feeding hopper is lifted by hydraulic control, more convenient for maintenance.

4、 Four hydraulic legs are more suitable for the construction site, making working steady and safe.

5、The oil pump will stop working automatically when the lifting hopper is lifted to the specified height, which can not only prolong the service life of the oil pump, but also can reduce the energy consumption and workers’ difficulty in operation.

6、The discharging outlet of the feeding hopper can be open and closed easily, the discharging amount can be adjusted according to the guniting amount coming from the dry-mix shotcrete machine, saving the hand regulation.

7、The accelerating agent self-feeding device can be used for feeding accelerating agent continuously and homogeneously, with stepless speed regulation, reducing the labor, saving the cost.

8、The air-cut brake makes parking brake safer.

9、The accelerating-agent feeding station is set additionally, which makes feeding more relaxed and safer.

The working switches are set on each side of the machine, more convenient for operation.
