Eckel Manufacturing Co., Inc. : Manufacturer of Hydraulic Power Tongs

Eckel 4-1/2 CMT

The Eckel Closed Mouth Tongs uses three sliding heads with each head equipped with a wide angle wrap-around die. This provides a maximum gripping area of 342 degrees; on the pipe. The CMT's utilizes the Hydra-Shift shifting technology which allows the operator to shift from high to low speed without stopping the tong. Reversing the pipe rotation is effortless and done simply by pulling the tong control in the opposite direction. There is no need to physically take out the jaws and turn them over as there is with other brands of closed head tongs. The CMT's also come with an optional backup that utilizes the same heads/dies as the tong.
