Pre-Loading Bridge Cables with a Battery Powered Hydraulic Pump

Pre-Loading Bridge Cables with a Battery Powered Hydraulic Pump
More than 20 cable strands were pre-loaded to the same tension with an RCH-Series hollow hydraulic cylinder powered by an XC-Series hydraulic pump. The portable battery powered pump was ideal due to the access restrictions of the cables.
