What Is Crane Rail Pad
Sep 15, 2025
A crane rail pad is a rubber component inserted between the crane rails and the bottom steel structure. Its main function is to absorb shock and vibration when the crane wheels run upon. It can also reduce wear and corrosion between the rails and the steel sole plate or other steel structures. However, it still allows certain movement of the rails to better disperse the wheel loads of cranes.
Features:
- Reduce noise and vibration
- Improve load distribution
- Reduce rail wear
- Reduce fatigue wear
Product range: GNEE RAIL supplies both continuous rubber pads and discontinuous rubber pads to fit different crane rail installation requirements.
Product material: The crane rail pads are either an elastic pad or a steel-reinforced, resilient pad. The elastic pad provides abrasion resistance, compression resistance, oxidant resistance, ultraviolet radiation resistance, and oil resistance. High lateral stiffness and resistance to movement from below the rail are guaranteed by the steel-reinforced resilient pad.
Product surface: The surface is composed of rectangular ribs, which not only enable closer contact between the crane rail and the steel surface but also increase elasticity for the steel plate.
Product application: Any crane rails and all railroad tracks.

Key benefits of GNEE Crane rail pads
High-performance material: high-quality nitrile rubber
Nitrile rubber is widely used in engineering scenarios under high load and harsh environments due to its excellent oil resistance, wear resistance, and aging resistance.
It is particularly suitable for heavy-duty lifting equipment, rail systems, and can withstand repeated dynamic ballast and contact with a variety of hydraulic media.
Excellent mechanical properties to ensure long-term load bearing and buffering
It has excellent pressure-bearing capacity and structural strength, and can cope with repeated rolling and vibration shock.
It is extremely flexible and effectively prevents tearing or structural damage during use.
This allows the rubber pad to maintain structural integrity and good performance under high-frequency crane operation.
Excellent aging and durability
The hardness is stable, indicating that it can still maintain ideal elasticity and support strength under a thermal aging environment.
There is almost no permanent deformation under long-term compression, ensuring close contact with the track beam and excellent stability.The hardness is stable, indicating that it can still maintain ideal elasticity and support strength under a thermal aging environment.
Applicable to a wide range of temperatures (-25℃ to 100℃)
It can maintain performance without degradation in winter in cold areas or summer in high-temperature factories, and is suitable for use in different climate conditions around the world.
Avoid problems such as hardening, cracking, or reduced elasticity caused by temperature changes.
Good rebound performance, improves vibration reduction effect
It has good energy absorption and release capabilities, effectively alleviates the impact vibration generated by the operation of lifting equipment, extends the life of the track system, and reduces noise.
