Abstract
A system for loading a patient transport apparatus into a vehicle is described. The system includes a loading and unloading system including a track and a trolley supporting a receiver movable between locked and unlocked configurations. The system also includes a patient transport apparatus for attachment to the loading and unloading system including a base, a litter, and a lift mechanism to facilitate arranging the litter at different heights relative to the base with an actuator movable between fully-retracted and fully-extended configurations, a coupler for engaging the receiver to secure the patient transport apparatus, first and second sensors configured to output a first signal and second signal and a controller to determine a target lift configuration during unloading from the emergency based on first and second values and to drive the actuator to the target lift configuration to limit relative movement between the patient transport apparatus and the trolley.
