ABSTRACT:
In a lift truck of a type that, using a brake controller20,a traveling motor3can be braked by an electromagnetic brake17,the brake controller20,when it detects the brake operation of a brake operation device, not only actuates the electromagnetic brake17but also detects the truck body weight and traveling speed of the lift truck, thereby electrically braking the traveling motor3in such a manner that the electric brake force can be increased or decreased in correspondence to whether the thus-detected truck body weight is heavy or light as well as the electric brake force can be increased or decreased in correspondence to whether the thus-detected traveling speed is high or low.
