Pre-Loading Bridge Cables with a Battery Powered Hydraulic Pump
Customer
ALE Heavy Lift
Location
Erlangen, Germany
Challenge
ALE Heavy Lift was tasked with skidding an 800 ton railway bridge over a highway using skidding equipment and steel strands. The steel strands were used as diagonals within the skidding towers and as a connection in a longitudinal direction between the skidding supports. Before the bridge could be skided onto the towers, more than 20 cable strands had to be pre-loaded to the same tension.
Solution
A RCH-Series hollow hydraulic cylinder powered by an XC-Series hydraulic pump was used to pre-load the cables. Due to the quantity and access restrictions of the cables, a battery powered pump provided an ideal solution; portable, fast and safe.
