MK31-QR is an electric actuator designed for medical bed applications, with a maximum thrust of 4000N. It can support the mechanical emergency release handle design of the hospital bed, and the steel cable can be manually pulled to release the lead screw of the MK31-QR, so that the MK31-QR can quickly level the bed by gravity for medical emergency treatment of the patients in the bed.
