ABSTRACT:
A motorized reel is mounted at a fixed location and constructed and arranged to reel-in a lead rope having a runner-connector at its free end. A set of controls including a throttle and a brake is provided at the fixed location for reeling-in the runner at a controllable speed which, typically, is at least slightly faster than the runner is used to running when unaided. Just ahead of the runner-connector on the lead rope is a kill-switch actuator for closing a kill switch and thus terminating the reeling-in action as the runner nears the fixed location. The runner connector is a ring and pulley with a short length of secondary rope looped around the pulley sheave and provided with hand grips at its opposite ends so that normal alternating pumping action of the runner's arms is accommodated by left-right oscillation of the secondary rope along the pulley sheave.
