22kg rail weighs 22.3kg per meter and is designed for crane tracks, overhead transport systems, and other industrial setups requiring higher load-bearing capacity. This model bridges the gap between light and heavy rails, suitable for applications such as light duty-gantry cranes or transport in logging and mining sites.
How to Install 22kg rail Properly?
The installation of railroad tracks is a highly technical process that demands accuracy, experience, and compliance with strict engineering standards.
- To properly install 22kg rail, begin by preparing a clean, level support surface and placing grooved elastic pads on it. Accurately position the rail sections according to the design alignment and height, ensuring minimal deviation. For a seamless finish, weld sections together using a method like thermite welding; if using mechanical joints, secure them with fishplates and bolts, keeping gaps small.
- The rail is then fastened using a clip system. Position the clips so the rubber component contacts the rail flange. Insert bolts with washers and initially hand-tighten them to compress the rubber nose. Finally, use a calibrated torque wrench to tighten the nuts to the specified torque, ensuring a secure hold.
- Conclude by grinding any joints smooth, applying anti-corrosion coating to machined surfaces, and conducting a final inspection. This inspection must verify all dimensions, straightness, and levelness meet the required design standards before the track is put into operation.
