Abstract
A mobile X-ray apparatus has a carriage provided with at least one pair of independently driven driving wheels and a motor. The carriage includes a driving handle, which comprises sidebars, attached to a rotation axis solidly fixed to the carriage, and a crossbar, which is connected to the sidebars in an articulated manner to allow the turning movement of the sidebars about the said axis independently of each other. The apparatus also controls the operation of the motor by movements of the handle. The sidebars are provided with a toothed rim that moves along with the movement of the respective sidebar. The movements are measured by a potentiometer, which converts the movement into an electric signal by which the motor of the driving wheels is controlled.
