Segment lifters

Definition

Segment lifters are specialized construction equipment used to handle and position precast concrete segments during the assembly of segmental bridges. These devices play a crucial role in both incremental launching and segmental construction processes, ensuring that the segments are accurately placed and securely fastened. By providing the necessary lifting capability, segment lifters facilitate efficient construction while maintaining safety and structural integrity.
