CRANE RAIL PADS

Crane Rail Pads are designed to reduce the wear and corrosion of the rail and to absorb uneven surfaces ultimately reducing stress and fatigue.

UR-Mk2 (Individual Rail Pad)

UR-Mk2 Individual crane rail pads are designed for runways where the rails are discontinuously supported.

Features & Use: ​

 

  • Provides even stress distribution in support structure.

  • Reduces vibration and shock.

  • The pads tapered edges reduce edge loading on soleplate and grout

  • Lips prevent pad displacement from soleplate

UR-Mk7 (Continuous Rail Pad)

Continuous rail pads are made of vulcanised nitrile rubber with wear resistance, compression resistance, oxidation resistance, anti ultraviolet radiation and oil resistance. The grooves on the surface can ensure the rail pad tight contact with its support to reduce the abrasion. The continuous rail pad is reinforced with a steel strip to ensure high lateral stiffness and prevent movement from below the rail. The steel strip is thin enough so that the rail pad can be rolled when transportation. The width of the steel strip is proportional to the width of resilient pad. They are widely used in ports, shipbuilding, steel plants, coking plant, cement plants, electrical power plants and other industries.

  • Reducing noise and structural vibration, it is manufactured with stress and wear resistant synthetic elastomer. It fully incorporates a special double textile structure which makes the pad transversally rigid, even in the most extreme operating conditions, the pad does not misplace laterally.

  • It dampers irregular contact between rail and ground.

  • Ensures superior adherence thanks to its grooved surface.

  • It is completely resistant against water, oil, and grease.

  • It spreads wheel load in a wide area and therefore decreasing pressure which may occur on a single area which greatly reduces load concentrations and fatigue stress.

  • Rubber brackets have been strengthened by steel reinforcement in the inner side. It’s strength against crushing and widening has been increased.

  • It has a great degree of recovery, and It decreases maintenance works of crane road.

Installation Instructions: 

​

Rail pad should be narrower than the rail it is supporting (nominally 5mm).

The pad is normally supplied in 12 metre lengths. The flutes of the pad are placed facing upwards. The pad may be cut to precise length of rail. It can be cut with a hacksaw or jigsaw. No installed length of pad should be less than the spacing between three pairs of crane rail fixing clips. Before installing UR 7 pad, the supporting area should be clean and free of oil, grease or any projections likely to damage the pad. It is preferable that the steel structure below the pad is not painted. If the rail is to be welded the pad should be protected from excessive heat during welding by being removed under the weld or by being protected with a thermal barrier. Our technical department will be pleased to advise on the suitability of UR 7 pad in specific installation conditions.
