Abstract

See full text

A patient transport apparatus for transporting a patient over a floor surface is described herein. The patient transport apparatus includes an auxiliary wheel assembly including an auxiliary wheel, an auxiliary wheel drive system, and a control system for operating the auxiliary wheel drive system based on user commands. The control system includes a processor that is programmed to receive a user command to operate the auxiliary wheel drive system in a drive mode and responsively operate a motor control circuit to transmit power signals to a motor to rotate the auxiliary wheel. The processor is also programmed to receive a user command to operate the auxiliary wheel drive system in a free wheel mode and responsively operate the motor control circuit to enable the auxiliary wheel to rotate relatively freely with the auxiliary wheel in a deployed position.
