A slingbar includes a sling attachment member. The sling attachment member includes a frame including a base having a top end and a bottom end, and a hook extending from the bottom end to a hook terminus. The hook terminus and the top end of the base define an opening. The hook, base, and opening bound an interior of the attachment member. A closure element includes an outboard gate hinged to the hook terminus and an inboard gate hinged to the base. The gates have a default state in which each gate extends laterally only part way across the opening.

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.

A chargeable hoist for a subject transport unit including a rail system having one or more rails includes a body, a contact plate moveable relative to the body and electrically conductive, a control system operable to move the contact plate relative to the body, and an accelerometer configured to measure a movement of the body. The control system moves the contact plate relative to the body and out of engagement with the one or more rails as a function of the measured movement of the body.

A sling bar includes a frame defining a central hub, a first hook extending from the central hub, and a second hook extending from the central hub. The central hub includes a wall defining an internal hollow region and an external hub surface, the internal hollow region shaped and sized to receive a ferromagnetic insert therein, and one or more niches formed within the wall and recessed into the wall from the external hub surface, the one or more niches arranged radially around the internal hollow region and sized and shaped to receive a hand control device.

An inflatable support strap for positioning and rotating a horizontally laying subject on a support surface, the inflatable support strap includes an elongate body comprising a first end and a second end spaced a distance apart from the first end, the first end and the second end each comprising at least one loop extending therefrom, and the elongate body defining a cavity. The inflatable support strap also includes one or more bladders disposed within the cavity, the one or more bladders configured to be selectively inflated or deflated.

An overhead lift apparatus includes a mounting structure and a rotatable assembly configured to attach a lift unit to the mounting structure. The rotatable assembly is rotatable with respect to the mounting structure about an axis of rotation. The apparatus also includes a rotatable electrical interface disposed in the rotatable assembly, the rotatable electrical interface comprises a static portion and a rotatable portion attached to the rotatable assembly such that the rotatable portion rotates in conjunction with the rotatable assembly. The apparatus also includes a first electrical connector extending from the static portion to a power source connector configured to be connected to an external power source for the lift unit. A second electrical connector extends from the rotatable portion such that the rotatable electrical interface is configured to provide power from the power source to an end of the second electrical connector via the first electrical connector.

Lifting devices for positioning a lift actuator in a high range position and a low range position are disclosed. The lifting devices may include a lift mast, a lift arm pivotally coupled to the lift mast, a lift actuator having a first end and a second end, and a linkage member having a first end and a second end. The first end of the lift actuator is pivotally coupled to the lift mast. The first end of the linkage member is pivotally coupled to the lift arm and the second end of the linkage member is pivotally coupled to the second end of the lift actuator such that the lift actuator includes a high range position relative to the lift arm and a low range position relative to the lift arm.

A sling bar includes a frame defining a central hub, a first hook extending from the central hub, and a second hook extending from the central hub. The central hub includes a wall defining an internal hollow region and an external hub surface, the internal hollow region shaped and sized to receive a ferromagnetic insert therein, and one or more niches formed within the wall and recessed into the wall from the external hub surface, the one or more niches arranged radially around the internal hollow region and sized and shaped to receive a hand control device.

A person lift system includes a motor and a sling bar coupled to the motor. The sling bar includes a first attachment hook at a first end region of the sling bar and a second attachment hook at a second end region of the sling bar. A sling includes a main body section and a plurality of loops coupled to the main body section. Each of the plurality of loops is configured to attach to one of the plurality of attachment hooks. A first electronic reader is coupled to the sling bar near the first attachment hook. A second electronic reader is coupled to the sling bar near the second attachment hook. Each of a plurality of short range wireless tags is coupled to a respective one of the plurality of loops.

An inflatable support strap for positioning and rotating a horizontally laying subject on a support surface, the inflatable support strap includes an elongate body comprising a first end and a second end spaced a distance apart from the first end, the first end and the second end each comprising at least one loop extending therefrom, and the elongate body defining a cavity. The inflatable support strap also includes one or more bladders disposed within the cavity, the one or more bladders configured to be selectively inflated or deflated.
