A brake assist system for patient handling equipment such as a patient bed includes a drive wheel. The wheel includes a brake assist system operated by control of a controlled unit which is operable to sense tilt of the handling equipment and to apply partial breaking to the wheel when it is detected that the equipment is on a slope. The control unit controls a maximum speed of the equipment down the slope, in order to protect the patient and to assist a care worker. The control unit disengages the brake assist mechanism when it is detected that the equipment is on a horizontal surface.
