Overview
The SPB7-T is an electric hydraulic pump-type wet shotcrete machine designed for wet shotcrete application in slope stabilization and excavation support, mining, tunneling, culvert, subway,slope… The machine adopts hydraulic transmission to pumps the concrete to a certain distance or to the nozzle, and then uses compressed air to spray the concrete onto the supporting surface. At the same time, add an appropriate amount of accelerator to mix with the concrete at the nozzle, and the amount of accelerator is adjusted by the metering pump.
