Abrégé

A self-propelled track drive module for an emergency stretcher, includes a left-side track drive unit and a right-side track drive unit. A frame, having a front end and a rear end, is disposed between the left-side track drive unit and the right- side track drive unit. The frame has a mounting structure for receiving an emergency stretcher and for releasably securing the emergency stretcher to the frame. The mounting structure is configured to support the emergency stretcher such that rolling wheels of the emergency stretcher do not contact a ground surface therebelow when the emergency stretcher is in a mounted condition.

Abrégé

A self-propelled emergency stretcher includes an elongate frame having a set of wheels a track drive unit mounted thereto. The set of wheels includes first wheels at a front end of the frame and second wheels at a rear end of the frame, and the track drive unit is mounted between the first wheels and the second wheels. A plurality of actuators is configured to raise and lower the first wheels and the second wheels relative to the frame, so as to selectively switch the emergency stretcher between a self-propelled configuration and a manually-propelled configuration. In the self- propelled configuration the first wheels and the second wheels are out of contact with a ground surface below the emergency stretcher and the track drive unit is in contact with the ground surface. In the manually-propelled configuration the first wheels and the second wheels are in contact with the ground surface and the track drive unit is out of contact with the ground surface.
