摘要： A motor driven, hand-held tubing cutter is disclosed, which can be held stationary by a worker while cutting the tubing, and does not require that the tubing be held in a vise or other clamping tool. The device is reversible, and upon completion of the cut, the device can be reset automatically to its initial position to receive a subsequent length of tubing for cutting. The tool has a motor-rotated cutting head into which the tubing to be cut is inserted, one or more cutting blades which are urged into cutting contact with the tubing wall by the motor-driven rotation of the head in cooperation with indexing bosses, and, once the tubing is cut through, reversal of the driving motors causes the blades to be retracted into the head, resetting the tool for further cutting. The tool may be used to cut any cuttable metal or plastic tubings, including tubing of aluminum, brass, copper, steel, ABS, PVC, polycarbonate, phenolic, etc.

摘要： A portable wire pulling device is disclosed which can be secured into pulling position and easily released. The device has a housing; a frame with vertical hollow posts, a sheave between the posts, a motor-driven extension clamp moveable outwardly from the posts to engage and secure to a stationary object; a motor driven capstan mounted on the housing; controls and selectors to select between AC and DC and to control the motors; and wheels and hand grips for moving the device; such that the device can be secured into position by the extension clamp and a wire feed pulling line attached to wires to be pulled routed over the sheave to the capstan and the wire pulled securely and evenly by the capstan. The device can be run on AC or DC power, or AC power can be used to charge internally mounted DC batteries. A full battery charge will allow the device to operate for a full eight-hour shift, and it can easily be recharged overnight. A number of pulling speeds can be obtained, depending on the type of control and selection device used, from slow speeds for precise control to fast speeds for high productivity.
