Abstract
The present invention relates generally to rope drives working with high-strength fiber ropes such as crane hoists, boom adjustment gear, trolley traveling gear, etc. The invention in this respect in particular applies to hoist drums for the rope hoist winch of such a fiber rope drive having a drum jacket body which is provided with grooving at the peripheral side and having two guard plates adjacent to the drum jacket body at the end sides. The invention further relates to a rope pulley for such a fiber rope drive having a rotatably supported pulley body whose jacket surface has at least one rope groove. In accordance with the invention, the rope grooves have a flat-pressed, round groove contour which differs from the circular and which has a larger radius of curvature in the region of the groove base than in the region of the groove flanks adjacent thereto.
