  • Publication number: 20200377347
    Abstract: A switch assembly for a lift unit includes a switch, an emergency stop device, and a reset actuator. The switch is arranged to move between a closed position, wherein the switch electrically couples a lift motor of the lift unit to an energy source, and an open position, wherein the switch electrically decouples the lift motor from the energy source. The emergency stop device is coupled to the switch and arranged to move the switch from the closed position to the open position. The reset actuator is coupled to the switch and arranged to move the switch from the open position to the closed position, wherein the reset actuator is controllable to move the switch from the open position to the closed position.

  • Publication number: 20200168308
    Abstract: Rail-mounted lift systems, systems comprising the same, and kits of parts for retrofitting rail-mounted lift systems are disclosed. A lift system includes a rail having a carriage support channel formed therein, a carriage slidably disposed in the carriage support channel for relative movement to the rail, a lift unit coupled to the carriage, the lift unit having a motor that extends and retracts a lifting strap, and a locating system having a first component and a second component separate from the first component. One of the first and second components is a transmitter providing a code that corresponds to a predetermined location and the other is a receiver detecting the code when the first and second components are moved in proximity to one another due to movement of the carriage along the rail.

  • Publication number: 20200085659
    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.

  • Publication number: 20200085658
    Abstract: A patient lift system includes a motor and a drum. The drum is operably coupled to the motor. The drum can be selectively driven to rotate by the motor. A housing surrounds at least the motor and the drum. A load-bearing member is provided that includes a first end and a second end. The first end of the load-bearing member can be operably coupled to at least one of the housing and the drum. The second end of the load-bearing member can be operably coupled to a patient support assembly. An electrically conductive member can be positioned within the load-bearing member. A user interface is configured to actuate the patient support assembly in vertical and horizontal directions.

  • Publication number: 20200085657
    Abstract: A method of determining a lifting event of a person lifting apparatus is provided. The method includes receiving one or more of (i) current load information from a current measuring device that is indicative of current drawn by an actuator operatively connected to a lifting strap of the person lifting apparatus; (ii) strap position information from a position sensor that is indicative of a paid out length of the lifting strap of the person lifting apparatus; and (iii) weight information from a weight sensor that is indicative of a load supported by the lifting strap of the person lifting apparatus. A computing device comprising a processor using logic is used to identify at least one of a raising event, a repositioning event and a lowering event based on the one or more of the current load information, strap position information and weight information.
