Product Description Of Double Beam Grider Long Span Bridge Girder Erection Machine

The highway Bridge –erecting Crane is designed for highway and railway.

It is mainly used for hoisting (lifting) of concrete girder in bridge construction (bridge building) of general railway and highway.

Launching gantry is large bridge construction equipment which can install precast girders span by span for highway bridge.

With unique and reliable girder structure, the launching gantry allows air current to pass through the hole as it works high above the ground, thus greatly reduce wind impact on main girder, quite safe.
