Established in 1998, Anping County Boli Hardware Wiremesh Products Factory has been a leading manufacturer of railway fastening systems. Our Elastic Rail Fastening Assembly for Heavy Duty Railway Tracks and Mining Operations is engineered to withstand extreme loads and harsh environments. With annual export value exceeding US$5 million, we supply reliable track components to markets worldwide including North America, South America, Africa, and Southeast Asia. This assembly combines superior elasticity with robust construction, ensuring long-term stability and safety for both heavy haul railways and demanding mining operations.

Our elastic rail fastening system is designed to securely clamp rails to sleepers while absorbing dynamic forces from heavy trains and mining equipment. It minimizes track deformation, reduces maintenance frequency, and extends service life. The assembly consists of a spring clip, bolt, nut, washer, and insulating components, all made from high-grade spring steel or alloy steel with anti-corrosion treatment. The product is available in various configurations to match different rail profiles and sleeper types.

Key Features & Technical Specifications

  • High Elasticity: Spring clip design provides consistent clamping force, reducing rail wear and noise.
  • Heavy Duty Capacity: Suitable for axle loads up to 40 tons, ideal for mining railroads and mainline freight.
  • Corrosion Resistant: All steel components are treated with anti-rust coating or hot-dip galvanizing.
  • Easy Installation: Pre-assembled units reduce on-site labor time; compatible with manual or hydraulic tools.
  • Vibration Damping: Elastic pad under base plate absorbs impact, protecting sleepers and ballast.
  • Temperature Tolerance: Operates effectively from -40°C to +80°C.
  • Customizable: Available in different sizes, colors, and packaging options upon request.

Packing Pallet / Wooden Case (export standard)

Customer Benefits: By using our elastic rail fastening assembly, railway operators and mining companies can significantly reduce track maintenance costs. The consistent clamping force prevents rail creep and gauge widening, ensuring safe operation at higher speeds and heavier loads. The durable spring clip can be reused multiple times, offering long-term economy. Our fastening system also helps to lower noise levels, which is critical for urban and underground mining environments.

Our factory in Hengshui, Hebei, China, has over 25 years of manufacturing experience. We have exported to over 15 countries across North America, South America, Europe, Africa, and Asia. Our annual export value of US$5–10 million reflects the trust global customers place in our products. We ship from major ports including Tianjin, Qingdao, Shanghai, and Foshan, ensuring timely delivery. We invite you to contact us for samples, technical drawings, or customized solutions. Our team is ready to support your railway and mining projects with reliable, cost-effective fastening systems.
