Key Features
Full-penetration fillet welding (5mm throat thickness) ensures a rigid connection between the clip and rail support, eliminating bolt loosening risks.
Constructed from weldable grade steel with M24 Grade 8.8 bolts, capable of withstanding extreme shear forces and fatigue.
Integral vulcanized rubber block provides controlled clamping force, reducing rail wear and noise while accommodating minor thermal expansion.
20mm horizontal adjustment allows precise alignment during installation, critical for heavy cranes with guide rollers.
Suitable for 85.5–221 kg/m rails, including specialized heavy-industry profiles:
Chinese: QU100, QU120
European: A150, MRS125, ISCR140
Two configurations:
(S) with rubber pad: For enhanced vibration dampening.
(H) without pad: For direct rail-to-support welding.

Installation & Maintenance
Constructed from forged steel with an M24 Grade 8.8/10.9 bolt (80mm, Customizable length), capable of withstanding shear forces and fatigue in ultra-heavy applications.
Two-piece interlocking design locks securely upon tightening, minimizing rail movement under dynamic loads.
20mm horizontal adjustment allows fine-tuning during installation or maintenance, critical for aligning guide roller-equipped cranes in high-precision setups.
Integral vulcanized rubber block provides controlled clamping force, reducing noise, wear, and thermal expansion impacts.
Suitable for 85.5–150.3 kg/m rails across specialized standards:
Chinese:QU100, QU120
European: A120, A150
Industrial: MRS125 , ISCR140
Two configurations:
(S) with rubber pad: Enhances vibration dampening for heavy machinery.
(H) without pad: For direct, high-stability rail-to-support installation.
Galvanized finish and high-strength materials ensure longevity in harsh environments (e.g., coastal ports, mining sites with corrosive conditions).
