W20-221 Rail Clip

Ultra-Heavy-Duty Adjustable Crane Rail Fixing—— W20-221 Rail Clip

The W20-221 rail clip is built to withstand extreme horizontal forces up to 305kN, offering 21mm rail adjustment for precise alignment and dependable performance in the most demanding industrial environments.

Product Overview

The W20-221 crane rail clip is engineered for ultra-heavy-duty applications where reliability and performance are critical.

Its low-profile design ensures compatibility with cranes equipped with guide rollers, making it ideal for ports, heavy-industry facilities, and large-scale logistics hubs. With a massive 305kN side load capacity, this clip offers unmatched stability and safety.

Time-Tested Reliability: The W20-221’s proven design has been deployed successfully worldwide for years, standing up to diverse industrial challenges.
Welded for Accessibility: Welded directly to rail supports—no below-access required, making it perfect for elevated or confined installations.
Secure Locking Mechanism: Tightening the Grade 8.8 bolt locks the clip’s two main parts together, paired with a self-tightening feature to resist loosening.
Low-Profile Versatility: Works with cranes equipped with guide rollers, avoiding interference with operational components.
