Introduction Tunnel lining trolley it was based on the motor drive travel mechanism to drives the trolley running. As a tunnel concrete molding machine which effect is adjusted the formwork right and formwork removed by hydrocylinder with screw jack. Tunnel trolley is widely used for highway, railway bridge construction,inter-city subway and public works. The tunnel trolley is includes three sizes 6m,9m and 12m. Which was travelling, effective support forms and form removal by the hydraulic system. Product Description Tunnel trolley generally adopts full hydraulic operation and automatic walking to improve work efficiency, reduce the working strength and ensure the quality of lining. In order to meet the requirement of the construction site, we can produce variable section multifunction tunnel trolley with consumers' design, which would be convenient operation and reliable performance. In order to prevent the on site installed trolley from rusting before using, we make a special treatment on the surface of the formwork, so that the trolley could keep as bright as ever and the lining surface of concrete is flat and smooth. Tunnel lining platform trolley(tunnel trolley for short) is a construction equipment for tunnel second concrete lining. Matched with other auxiliary machinery, it could greatly reduce labor force, improve the mechanical efficiency of the tunnel second lining construction and improve the construction schedule. It has the advantages of low cost, reliable structure, convenient operation, good tunnel molding surface etc and widely used in highway, railway, water conservancy & hydropower project, municipal, national defense industry construction and other constructions. According to the different tunnel section and different construction, tunnel trolley could be divided into the side & roof arch, fully round acerate-beam type, fully round through type, the bottom platform needle-beam type, lifting sliding formwork, rolling formwork etc. According to the actual requirements, the consumer could select full hydraulic self-walking type, full hydraulic driven-walking type, mechanical large platform type, combined platform type etc. According to the tunnel length and the construction period, the consumer could choose the length of tunnel trolley with 6 meters, 7.5 meters, 9 meters, 10.5 meters or 12 meters
