Circular Tunnel Needle Beam Trolley

Circular Tunnel Needle Beam Trolley

Three sets of hydraulic cylinders are installed on the steel mold to complete the vertical mold and the mold removal work. A screw jack is installed at a corresponding position of the top mold and the side mold, the oil cylinder is extended, and the screw jack is tightened after the steel mold is positioned, thereby ensuring the accuracy of the lining size and reducing the cylinder load. When mold removal, first remove the top mold, then take off the left and right side molds. 
The Needle Beam Trolley rises upward with the vertical cylinder of the outrigger, so that the whole Needle Beam Template Trolley rises and the bottom mold is separated from the concrete. The specific steps are as follows:
The hydraulic system retracts the Needle Beam Geared Trolley bearing legs;
Start the hoisting Needle Beam Trolley mechanism to operate the needle beam to the next position to be poured;
Hydraulic Concrete Needle Beam Trolley system expenditure bearing legs are in place;
Demolition of the plug template
The hydraulic system gathers the top template;
