Product Overview

Segment Lifter is used in the construction of precast segmental balanced cantilever bridges, where pre-casting is possible and the segment can be transported below the span.

The self launching segment lifter is launched through hydraulic system which gives a safe launching for the equipment. The segment lifter allows faster erection and is therefore addressed to bridges with a great number of spans. Segment lifters are consist of structural steel, however a segment lifter is not required to span from one pier to the next and therefore it does not contain as much steel as the launching truss.

Two segment lifters work in tandem with its mirror equivalent, with one lifter erecting in one direction from the pier and the second lifter erecting in parallel in the opposite direction.

Shenghua Heavy Crane Group has developed several types of bridge deck erection system segment lifter customized for the various erection requirements and conditions of precast segmental viaduct.
