Abstract
The cable lift system provides assistance to movement of a flexibly suspended payload actuated by operator input into one or more sensing devices attached to the payload. The sensing device is configured to collect information about the typical push-pull and lift-lower motions of an operator moving the payload horizontally and/or vertically, such that the operator's input to the sensor is intuitive and is provided in a manner which is substantially transparent to the operator. The assist mechanisms included in the system are actuated by a controller processing signals received from the one or more sensing devices on the payload. Movement assistance is provided such that the manual effort required by the operator to overcome the inertia of the payload in a starting or stopping event is substantially relieved, thus minimizing the ergonomic impact of the starting and stopping events on the operator.
