XINGRAIL Perforation Type Forged Steel Flexible Self-Locking 3224/20/44 is easier and more efficient to install and more economical than welded platens. Aligning the bolt holes with the holes reserved in the carrier beam or concrete and using the bolts through the platen to press the rails together, the XINGRAIL rail fasteners are equipped with XINGRAIL rail fasteners are equipped with vulcanized monolithic rubber blocks, which can greatly reduce noise and improve the working environment while fixing the rails.
XINGRAIL 3224/20/44 Crane Rail Mounting Clamps are constructed of Q355B hot forged steel and vulcanized rubber blocks that are dynamically adjustable with a self-locking feature that allows the lever to lock automatically by means of a tilting lever cap and weldable base. Fixed to the LIGHT rail system. It has 1 set of M20 grade 8.8 high strength bolts. xingrail 3224/20/44 crane rail mounting clamp bolts to the rail and can withstand horizontal transverse forces of up to 38 KN (3.9 tons) with a leveling adjustment of 13 mm. its low profile allows it to be used with cranes fitted with guide wheels.

Core Technical Specifications
| Parameter | Specification | Engineering Note |
| Max Lateral Force Resistance | 150 kN | Approx. 15 tons/piece; designed for heavy-duty overhead and gantry crane runway systems. |
| Lateral Adjustment Range | 20 mm | Provides an extensive adjustment margin to accommodate track installation errors and structural settlement. |
| Bolt Tightening Torque | 350 Nm | Recommended tightening torque based on high-strength M20 fastening hardware. |
| Locking Mechanism | Flexible Self-Locking | Wedge-action mechanical interlocking prevents the clip from backing out under severe dynamic vibrations. |
| Installation Method | Bolted Base / Perforation | Secured via through-bolts or threaded studs to the underlying steel girder or concrete soleplate. |
Material & Manufacturing Process
| Component | Material Standard | Features & Surface Treatment |
| Upper Clip & Base Plate | Forged Steel Q355B | Equivalent to S355J2 / ASTM A572 Gr 50; precision forging guarantees high impact toughness and structural reliability. |
| Fastening Bolts & Nuts | Grade 8.8 or 10.9 | Treated with Hot-Dip Galvanizing (HDG) or heavy zinc plating for superior resistance in harsh industrial environments. |
| Integrated Flexible Tongue | Vulcanized NBR / CR | Shore A Hardness 75°±5°; Nitrile/Chloroprene compound absorbs mechanical shock, dampens noise, and prevents rail track wear. |
