TG43 WJK Rail Clamp for P43 Rails

The TG43 WJK Rail Clamp is a standard welded rail fixture specifically engineered for securing P43 (43kg/m) rails to steel or concrete crane beams. It is characterized by its three-part assembly consisting of a weldable base, an upper cover plate, and a spherical hinge T-bolt.

Signum Rail Fastening is able to offer rail clamps(rail clips) according to the client’s requirements.

Technical Specifications & Performance

The performance of the TG43 is largely determined by the material and bolt grade selected: 

Variant   Base Material Bolt Grade Max Lateral Force Tightening Torque

Standard   Q235 Steel         Grade C         45 KN                                 150 Nm

Enhanced   Q345 Steel         Grade 8.8         55 KN                                 220 Nm

Key Features

• Spherical Hinge Connection: The T-bolt and base connect via a spherical joint, which allows for slight rail movement to reduce impact on the crane beam and braking system.

• Weldable Base: The base plate is welded directly to the support structure using low-hydrogen electrodes (such as E4315 or E5015), eliminating the need for drilling.

• Vibration Damping: Often used with elastic composite rubber pads (full-length or intermittent) to absorb shocks and minimize noise. 

Installation Steps

• Base Welding: Weld the base to the beam using two-sided (middle duty) or three-sided (heavy duty) welds.

• Assembly: Place the rail, then insert the T-bolt, wedge adjustment plate, and upper cover plate.

• Final Fastening: Install the washers and nut, then tighten to the required torque until the spring washer is compressed.
