TG43 Rail Clamp
The TG43 Rail Clamp, also referred to as WJK-TG43 rail clip, is a welded-type rail fixing system produced by Glory Track for securing P43 crane rails in heavy-duty industrial and material handling environments.
Made from Q235 or Q345 cast steel, this clamp provides excellent mechanical strength, precise alignment, and long-term stability under continuous dynamic loads.
Features of TG43 Rail Clamp
- Welded Base for Superior Stability — The clamp base is welded to the crane beam, transferring horizontal forces smoothly without drilling through the flange plate.
- Spherical Bolt Connection — The T-bolt connects to the base via a spherical joint, maintaining vertical alignment and reducing the impact of lateral loads on the crane beam and braking system.
- Adjustable Gauge Design — The wedge plate allows precise rail gauge adjustment with dual self-locking to prevent loosening during operation.
- Ease of Assembly & Maintenance — The top plate and T-bolt can be easily removed for inspection or replacement.
- Enhanced Load Resistance — Available in Q345 high-strength variant for heavier cranes and higher lateral forces.

Installation of TG43 Rail Clamp
Step 1 – Base Welding
Grind and clean the beam surface. Weld the base plate on the top flange using three-side or dual-side welds according to the crane load class. Ensure position accuracy within ±1.0 mm of beam centerline.
Step 2 – Bolt & Wedge Placement
Insert the T-bolt into the base slot and slide toward the rail. Place the wedge-shaped adjusting plate with the notched face upward.
Step 3 – Assembly & Tightening
Install the press plate, flat washer, spring washer, and nut sequentially. Adjust laterally to ensure full contact with the rail flange, then tighten to the specified torque ( Q>275 t, 220 Nm for heavy duty work).
Step 4 – Final Inspection
Check that all bolts are fully seated and that no play exists between the rail and the clamp.
