Crane rail clips fasten the rail to the crane or track beam. They secure the rail firmly, distribute load evenly, and absorb shocks and vibration. In high winds or sudden stops, they lock the trolley in place and prevent derailment.
Types of Rail Clips
Bolt‑Adjustable Clips
- Clamp rails to the beam flange with high‑strength bolts.
- Allow lateral adjustment to match rail width.
- Install and maintain entirely from above the rail.
- Ideal for mid‑sized cranes or where frequent inspection is needed.
Welded Clips
- Base plate is welded directly to the beam.
- Made from Q235 or Q345 carbon/low‑alloy steel.
- Withstand lateral loads of 40–55 kN per wheel.
- Often used with rubber pads beneath the rail to reduce impact.
- Suited for heavy‑duty, high‑frequency operations (steel mills, foundries).
Key Applications
Ports & Shipyards: Secure rails on container gantries and RTGs against wind and crane impact.
Steel Plants: Fix rails for overhead cranes in rolling mills and continuous‑casting lines.
Warehouses & Logistics: Maintain track accuracy for automated bridge and gantry cranes.
Other Heavy Industries: Support heavy lifts in metallurgical, heavy‑equipment, and defense facilities.
Materials and Corrosion Protection
Clips are usually made of high‑strength carbon or low‑alloy steel (Q235/Q345). Surfaces are hot‑dip galvanized or painted to resist rust. In marine or salt‑spray environments, stainless steel or specialized composite coatings may be used. All bolts, nuts, and washers are likewise treated.
Installation and Maintenance
Modern clips feature modular designs. All maintenance can be done from above the rail-no under‑rail access needed. Worn parts (pads, bolts, clamp bodies) can be swapped individually. Quick removal and replacement cut downtime and lower service costs.
