Drive system for patient lift

A drive system for a patient lift, the drive system comprising:

• a drum configured to control the vertical movement of a patient support mounting device of the patient lift via a load bearing member;
• at least one motor adapted to drive the drum, each motor being connected to a motor shaft gear via an output motor shaft;
• and
• a transmission connecting the motor and the drum, the transmission being adapted to transfer torque from the motor to the drum,
• wherein the transmission comprises a transmission interface adapted to interplay with the motor shaft gear,
• wherein the transmission interface is configured to receive the motor shaft gear in at least two configurations, each configuration being associated with an orientation of the output motor shaft relative the transmission interface,
• wherein the transmission interface comprises an input transmission gear adapted to interplay with the motor shaft gear,
• wherein the transmission comprises an output gear fixed to the drum, the output pear being connected to the transmission interface for receiving torque from the motor shaft gear, and
• wherein the motor shaft gear and the input transmission gear form a worm drive.
