@jacqueslees: Crane Rail Clip Fastening (Crane Rail Clamping Plate Fastening) Advantages of the crane rail clip fastening: 1. Overcomes the problem of clamp loosening that exists in conventional rigid rail fixing systems. 2. Reduces wheel load (wheel pressure) and the rail gnawing / wheel-rail interference of travelling crane wheels. 3. Reduces noise. 4. The clamping plate features a self-locking function and can reliably withstand the lateral forces transmitted from the crane wheels.
