Common Rail Clamps for P43 Rails

• TG43 Welded Rail Clamp: A standard for P43 crane beams, this two-part system consists of a weldable base and a detachable top plate. It often features a vulcanized rubber tongue (nose) to absorb shock and reduce vibration.

• WJK Series clamps: These are widely used adjustable clamps that provide roughly 13mm of horizontal adjustment to ensure perfect rail alignment.

• Gantrex Weldlok 43 clamps: A premium weldable clip option specifically tailored for the P43 section, known for its high durability and self-locking capabilities under lateral force.

• Bolted Clamps: While welded options are preferred for heavy-duty use, bolted rail clips are available for temporary or light-duty setups where welding isn't feasible. 

Key Specifications & Features

• Material: Typically constructed from high-strength forged steel or ductile iron.

• Lateral Load: High-quality P43 clamps are often rated for lateral loads around 38kN when used with grade 8.8 bolts.

• Adjustability: Most modern "soft-mount" clips allow for "infinitely adjustable" alignment to meet strict installation tolerances.

• Components: A standard assembly includes a base plate, cover plate, T-bolt (or hex bolt), nut, and specialized washers.
