1.The girder carrier is equipped with a diesel generator to meet the long distance transportation, control wheel pressure by double beam distribution hinge, ensure the force of girder carrier to U type beam is within the maximum load when the U beam runs by train in the future. Meet the requirements of curve, and it is equipped with double cabs for bidirectional driving.
1,The beam launcher’s overall height is low; the effects of each support are all on the cap and pad; guiding beam is in symmetry and easy for U-turn. The special adjustable sling can satisfy the working conditions of the U type beam eccentric hoisting crane.
2,the rear leg of beam launcher supports on the convex part al the middle of the cap to make the transporting girder carrier can one-time transport to the lifting position,
3,Rear feeding (long tail type or short tail type).
4,The beam launcher don’t need to lay the longitudinal rail for cross span. The edge beams erection in the place for one time.

Safety device:
(1) Weight overload protection device
(2) Lifting height limit device
(3) Low Voltage protection function
(4) Phase sequence protection function
(5) Emergency stop function

Control method:
(1) Pendent line control
(2) Remote control
(3) Cabin control
(4) Choose any two together

Project name: Section 8 of Shanghai rail transit No. 11 line south extension project
Project overview: The total length of rail transit No. 11 line is about 59 kilometers, of which the length of Section 8 is 7.66 kilometers, the main structural forms is: the upper part is a U type beam, and the lower part is an independent invisible pier, and the spacing between double standard lines is 5m; there are total 462 U beams, length is 24.5m-35m, and the weight is 205T
