摘要:
A person lifting apparatus includes a strap movement system. The person lifting device includes a housing and a lifting strap feeding device located in the housing. The lifting strap feeding device includes a motor connected to a drum and a lifting strap wound on the drum. A sensor provides a signal indicative of force on the lifting strap. A controller receives the signal from the sensor. The controller controls operation of the motor based on the signal. A user input is used to place the strap movement system in a fast mode during which the controller speeds up operation of the motor from a normal operating speed.
