Details

Trolley, also known as lining trolley, is mainly used for pouring concrete in tunnels, diversion tunnels, and secondary lining. The trolley is divided into two types of structures, one is the walking type and the other is the needle beam type. The trolley is mainly composed of a gantry frame and a formwork. The gantry frame mainly bears the weight, and the formwork is designed according to the shape of the tunnel. It has the advantages of automatic walking and hydraulic automatic positioning demolding (which can move up, down, left, and right).
