Abstract: The object of the invention is a bridge crane, which comprises a main girder, which is fitted to travel supported by end carriages essentially at both ends and which bridge crane further comprises a hoisting trolley traveling supported by the main girder and a rope drum mounted on bearings to rotate in an essentially stationary position, from which rope drum the hoisting rope is guided to a hook traveling along with the hoisting trolley. The hoisting rope is supported from below for at least a part of its essentially horizontal section.

Abstract: The invention relates to a vacuum gripping apparatus for moving roll-like loads, the loads being piled on top of each other and resting on their even end faces, the vacuum gripping apparatus comprising a suction plate (3) to be arranged against the end face of a load, the outer circumference (12) of the suction plate being provided with corner portions (19), side edges (21) that connect the corners of the portions being curved inward, that the outer circumference (12) of the suction plate (3) determines the maximum lateral dimensions of the structure above the suction plate.

Abstract: An electromagnetic brake is disclosed which comprises a brake wheel, a friction surface touching the brake wheel during braking and attached to an anchor plate moved by brake springs and an electromagnet which disengages the friction surface from contact with the brake wheel when a current is supplied to the magnet. To compensate for the wear of the friction surface, the brake has at least one retainer mounted on a bolt or shaft lying parallel to the axial direction of the brake. The retainer moves with the anchor plate towards the brake wheel and is provided with a directional element which limits the motion of the anchor plate away from the brake wheel. The brake is also provided with a wedge ring rotated by a spring which serves to move the electromagnet towards the brake wheel.
