The longer the wireline is, the more efficient the cylinder will be – especially with
shorter tongs. When the tong is at an angle other than 90 degrees the same line pull
gives less torque. The wireline’s recommended minimum is eleven (11) feet.
The cylinder has a maximum pull of over 35,000 pounds of force. The cylinder location
therefore must be tied to a structure capable of handling that force without damage or
safety hazard. Drawworks skid beams are commonly used.
