RL-CRIMP - Hammer Lug Crimper 6-4/0 AWG

Heavy-Duty Impact Crimping Solution for Large Gauge Cables

The RL-CRIMP Welding Cable Crimping Tool is a robust, mechanical impact tool designed for terminating heavy-gauge electrical conductors. Engineered for versatility and durability, this tool accommodates a wide range of wire sizes from #6 AWG up to 4/0 AWG, making it an essential instrument for fabricating custom welding leads, battery cables, and heavy equipment wiring harnesses. The unit features a simple yet effective design consisting of a V-shaped nest and a spring-loaded indenting ram.

Constructed from high-strength hardened steel, the body is built to withstand the repeated mechanical stress of hammer strikes. The integrated spring mechanism lifts the ram after each strike and holds the lug in position prior to crimping, ensuring proper alignment of the terminal and conductor. This design allows for single-handed operation when setting up the crimp. The tool is specifically engineered to create a cold-weld-like bond between the lug wall and the copper strands, minimizing electrical resistance and preventing hotspots at the connection point.

For optimal results, the tool can be operated using a 3-4 lb sledgehammer for field repairs or clamped into a heavy-duty bench vise for controlled compression in a workshop setting. Its compact footprint allows it to be stored easily in maintenance trucks or portable tool chests, providing a reliable crimping solution where hydraulic tools may be impractical or unavailable.
