3 ways to operate front and rear support legs of segments assembly beam launcher

Front and rear support legs are two main parts. Main function: support and jack the whole beam launcher, drive the beam launcher moving forward to cross spans and move laterally, move forward and backward by themselves.

There are 3 ways to operate front and rear support legs: jacking, longitudinal moving and horizontal moving.
A. jacking
Mechanical lock device is set on oil cylinder of front and rear support legs, after oil cylinder jacks them to proper position, cylinder rod protrusion shall be locked immediately with nuts and hoops, then the pump station can stop.
B. longitudinal moving of launching girder
Longitudinal moving cylinder stretches out and draws back to help realize longitudinal moving of launching girder
C. lateral moving of launching girder
Before adjusting lateral moving, lateral anchoring shall be loosened at first, then drive the lateral cylinder. After finishing the first action, loosen bolts by lateral moving device on front and rear legs, draw back the cylinder and lateral device at the same time, plug the bolts again for second action.
