ABSTRACT:
A device for measuring the tensile force in a winch wire. The apparatus includes a frame and three wheels connected to the frame. The first and third wheels are mounted on a common shaft, and the second wheel is mounted adjacent to the other wheels. A winch wire is trained over the first wheel, along a common tangent with the second wheel, over the second wheel and along a common tangent with the third wheel and thereover the third wheel. Conventional force measuring means can be used to measure the force pulling the first and second wheels together, which is caused by the tensile force in the winch wire. A tachometer is coupled to the common shaft of the first and third wheels, which can be used to measure the length of wire payed out from the device.
