A brake for a substantially light-constructed transport carriage includes a frame part, wheels and a part for drawing the carriage, the draw part being turnably carried in the frame part so that it can be lifted into vertical position to produce a braking effect. The problems encountered in existing brake mechanisms include wear and consequent abundant need of maintenance, and unreliable operation of the brakes. These are solved by arranging in the carriage between the draw means and the wheels, preferably the front wheels, a mechanism by which the front wheels turn in opposite directions when the draw part is lifted into its upper position. |
