draagrails

Draagrails are rails used in transport and machinery installations to provide the load-bearing surface for a moving carriage, trolley, or payload. They primarily bear vertical loads, while guiding rails constrain lateral movement. In practice they appear in systems such as overhead cranes, monorails, and conveyors, where a movable element must carry its weight on a fixed track.

Construction and design: draagrails can have various profiles, including I-beam, U-profile, or flat rails, and are usually made of high-strength steel with wear-resistant treatments. They may be mounted as single or dual rails and fixed to a supporting structure by bolts, brackets, or welding. In some configurations draagrails work together with guiding rails; the combination provides both load-bearing capacity and precise guidance.

Materials and maintenance: common materials are machined or forged steel, sometimes hardened for wear resistance; environments with corrosion may use stainless steel or coated variants. Regular inspection for cracks, deformation, or excessive wear is required, with measurements of wear and alignment. Replacement is performed when wear or damage exceeds specified limits. Lubrication and alignment of wheels or rollers influence lifespan.

Standards and installation: installation and maintenance are governed by applicable national and international standards and manufacturer specifications, which cover geometry, tolerances, anchoring, and inspection intervals.
