Crane Bumpers

3
Designed to withstand repeated heavy hits on bridge or ceiling cranes, these bumpers protect walls or beams as well as extend crane life. Made of polyurethane, all are abrasion resistant and are reinforced with a steel base plate for strength. These bumpers have either a hard or medium-hard rating to withstand high levels of impact. They're nonmarking and can be used outdoors. Mount them with screws.
Style 2 bumpers have a retaining loop for attaching a cable or lanyard.
Style 3 bumpers are for use with high-speed cranes that require greater deflection lengths.
