Model NO.: JQIV220t-35m
Type: Beam Launching Gantry
Tower Crane Type: Slewing Tower Crane
Sling Type: Wire Rope
Main Girder Form: Single Girder
Power Source: Electric
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.
