Abstract
A braking device for limiting the travel of an overhead crane traveling over rails temporarily increases its traveling resistance until it stops. The braking device includes at least one brake shoe which is mounted on the overhead crane and can be pressed against the rails with a force up to a level equivalent to the weight of the overhead crane. The brake shoe can be forcibly caused to move from a resting position a certain distance away from the rail into a braking position, in which the side of the brake shoe or shoes facing the rail can be pressed against the rail.
