Abstract: A drive system (100) for a patient lift. The drive system comprises a drum (321) configured to control the vertical movement of a patient support mounting device (11) of the patient lift via a load bearing member (12), at least one motor (270) adapted to drive the drum (321), each motor (270) being connected to an motor shaft gear (227), and a transmission (228) connecting the motor (270) and the drum (321), the transmission (228) being adapted to transfer torque from the motor (270) to the drum (321).

Abstract: A locking arrangement for a patient lift configured to selectively lock the vertical movement of a patient support mounting device connected to a lifting device of the patient lift via a load bearing member. The locking arrangement including a shape memory alloy element and a locking device. The shape memory alloy element is connected to the locking device and arranged to selectively actuate the locking device to control a locking force on an engagement member mechanically connected to a motor and the load bearing member of the patient lift. The present invention further relates to a patient lift including the locking arrangement.

Abstract: A ceiling lift tilt management system includes first and second motor units, which are attachable to a rail system of a medical care facility. Each motor unit includes a flexible strap, which can be coiled or uncoiled within the motor unit to raise or lower a spreader bar attached thereto. Coiling or uncoiling of the straps can cause raising or lowering of a sling attached to the spreader bars. The system also allows for tilting of the spreader bars by coiling or uncoiling a leading motor unit strap. The system includes a control system that measures the relative lengths of the two straps in order to ensure that relative tilt between the spreader bars does not exceed a threshold. Once a threshold tilt for height difference is reached, further user requests for additional tilting are prohibited. Patient comfort and safety are therefore ensured.

Abstract: A ceiling lift assembly includes first and second motor units which can be operated together in a dual mode configuration and which can be operated in a single mode operation, in which only one of the motor units is operative with the other motor unit being dormant. The system provides routines for switching between the single and dual modes of the assembly and which ensure that in each mode the necessary parts of the apparatus are in an operative condition, whereas those parts of the apparatus which are not used are placed in a storage condition to avoid inconvenience or injury to personnel and patients. The apparatus also includes a motor unit support device of a structure which can accommodate asymmetric loads, on one motor unit only without causing deformation of the support structure.
