Abstract
In a lift truck of a type that, using a brake controller 20, a traveling motor 3 can be braked by an electromagnetic brake 17, the brake controller 20, when it detects the brake operation of a brake operation device, not only actuates the electromagnetic brake 17 but also detects the truck body weight and traveling speed of the lift truck, thereby electrically braking the traveling motor 3 in 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.
