*There are various kinds of launching gantries available, the choice of which depends upon the geometry of site and construction sequence adopted by the designer.
highway bridge construction rail running launcher crane
Product Description
The capacity:60-200ton
The span : 20-50m
Control Mode: Pendant, Remote Control and Cabin Control.
Bridge Launching Crane is used to erect the prestressed concrete girder with span 50m and 51m. The assembly of girder adopts stub matching precast which assembled on site, the girder is put on the piers simply and then combined span by span firmly. The maximum weight of prestressed segment shouldn’t exceed 130/140t. The construction method of Bridge Launching Crane is the segmental hanging and then construction tensioning after the steel strands are threaded. The structure of the crane mainly consists of: automatic electric control system, truck operation mechanism, lifting trolley, excellent hardness of the steel structure as the bearing capacity.
Product Advantages
concrete box launcher crane remote control launcher crane is often used in port and railway cargo transportation. It is a high-quality hoisting machine with excellent structure, stable operation, safe and reliable, low maintenance cost and easy to control. Slag machine.
1. Horizontal operation landing the beam in place at one time;
2. Suitable for the construction of inclined (curved) bridge;
3. Light weight, convenient and quick transportation, installation
and removal;
4. Safe and reliable work, small longitudinal cantilever
deflection;
5. The legs are not landed on bridge deck when longitudinal moving,
reducing the pressure on the beam/bridge deck.
