Abstract
An improved load line sensor comprised of a support frame which clamps to the load line, a sensing unit fixed to the support frame, and a pivotal load line operator attached to the support frame in a close spaced relation to the clamping end thereof. The load line which is threaded through the pivotal operator is slightly deformed thereby so that line tension imparts a torque to the operator which reacts against the load sensing unit fixed to the support frame. The load line operator preferably has roller contacts wherein the pivoting and roller action of the operator minimizes the frictional influences which impair the operation of conventional devices.
