ABSTRACT:
A pneumatic winch apparatus applies a constant and non-jerking pull to a cable. The amount of pull or load applied to the cable is determined by the air pressure supplied to an air motor and the radius of a drive wheel connected thereto. A maximum cable-pull load can thus be applied with an automatic non-mechanical cutoff so that a load sensitive cable, such as a fiber optics cable, is not damaged during installation thereof. Moreover, the maximum load is maintained once it has been reached.
