Tweco Roto-Work Heavy Duty Rotary Ground Clamps
Tweco Roto-Work Ground Clamps are designed primarily to work in conjunction with the Tweco Roto-Ground Device. However, they may also be used for other high amperage grounding applications. The Roto-Ground shaft screws into the tapped back of the Roto-Work Clamp. The clamp is quickly attached or moved from one rotation weldment or fixture to the other without removing the Roto-Ground from it, saving on welding down time.
Roto-Work Clamps are made from a copper alloy. They come in 600, 1200 and 2000 ampere capacity. Number WCRG-2000 has two tightening screws. Number WCRG-600 works only with No. RG-230 due to its smaller shaft size. Large tightening screws and ample contact surface area provide cool, efficient operation.
