Crane rail pad is an elastic layer installed between the steel sole plate and the crane rail. Made primarily of natural rubber, synthetic rubber, polyurethane, and composite materials, it effectively improves load distribution, reduces vibration, and extends the service life of the crane rail system.
To accommodate the varying structural forms of steel sole plates, crane rail rubber pads are available in continuous and discontinuous types.
Continuous crane rail pads
Continuous crane rail pads are primarily used in conjunction with continuous steel sole plates. They are long strips and can be tailored to the length of the steel sole plates. They provide continuous support underneath the entire crane rail and are suitable for crane rail systems operating under heavy loads and high-frequency conditions.
Discontinuous crane rail pads
Discontinuous rubber pads are cut to the size of individual steel sole plates and installed above each steel sole plate. They offer flexible installation and facilitate partial replacement. They are primarily used in medium-load rail systems or applications requiring modular maintenance.
