This gantry crane for highway construction is employed to lift the concrete beam or bridge on to the supports of highway construction. It consists of girder longitudinal flat car, girder components, support system, crane transverse, longitudinal shift system, hydraulic system, electric control system, etc.

This highway construction crane can be rail type and step type. The rail type crane is mainly used for lifting of beams with length not more than 30m. While the step type crane need no rails, which has no pressure and damage to the highway beam/bridge because the legs can be landed on the supports.

With the high-speed development of highway construction, Weihua is developing various highway cranes adapting to the different working and use requirements such as skew bridge, curved bridge, Dislocation Bridge, heavy beam, variable beam, double-direction construction, construction in tunnels, etc.

Features:

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.
