Roto-Work Grounding 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 rotating 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.
