Abstract

A person lifting apparatus includes a first lifting strap feeding device including a first drum and a first lifting strap wound on the first drum. A second lifting strap feeding device includes a second drum and a second lifting strap wound on the second drum. A controller is communicatively coupled to the first lifting strap feeding device and to the second lifting strap feeding device. The controller includes logic that controls operation of the first lifting strap feeding device and the second lifting strap feeding device based on a comparison of current draws of the first lifting strap feeding device and the second lifting strap feeding device.
