Railway rubber boots for Concrete Sleeper
- Commodity name： Railway rubber boots for Concrete Sleeper
- Description
-
Railway Rubber Shoes, look like rubber boxes, also called rubber elastic boots, railway rubber boots, are set under the steel rails and concrete sleepers. The main function of the railway rubber shoes is to play an elastic buffering role, can reduce the stiffness of the contact surface between the rail sleepers and the ballast, and enhance the friction coefficient and elasticity. Therefore, the railway concrete sleeper rubber shoes can enhance the vertical and horizontal resistance of the sleeper and the ballast. Improve the bearing capacity and stability of the track, reduce the breakage and wear of the ballast particles under the sleeper, and at the same time enhance the elasticity of the ballast bed, and reduce the dynamic action and wear of the track and wheels.
Meanwhile, the railway rubber shoes are easily to disassemble, no need any tools or equipments, hance are beneficial to the efficiency of sleeper laying and maintenance.Kunshan Alex Railway Fastening Co.,Ltd are specialized in various types of railway elastic rubber products, such as rail pads and rail boots/shoes, as well as insulated plastic products(rail insulators, rail plastic dowel ). With our rubber vulcanizers and injection molding machines, as well as various advanced testing equipment, we have an annual production capacity of 8,000 tons. According to customer requirements, we can provide various rubber products as OEM or ODM.
