Rope drum of rope hoist and fastening device of hoisting rope

A rope drum of a rope hoist, having a drum cover for winding a hoisting rope around it, a power transmission member at one end of the drum cover for driving the rope drum, and a fastening device for fastening an end of the hoisting rope to the rope drum, wherein the fastening device:

• is fastenable near an end of the rope drum on the area between end surfaces of the rope drum and protruding from its surface;
• mainly comprises a cylindrical gripping part for installing a spliced rope loop of the hoisting rope around it, and a fastening protrusion arranged to extend from the cylindrical gripping part over the end of the rope loop and simultaneously forming a space partly enclosing the end of the rope loop, the fastening protrusion extending transversely in relation to the axis of the rope drum in the opposite direction than the hoisting rope and comprising a fastening area for fastening to the rope drum,
• wherein the power transmission member is a gearwheel, and
• wherein the gearwheel is driven from an outer periphery of the rope drum and forms part of the outer periphery of the rope drum, whereby the fastening device of the hoisting rope is fastened to the gearwheel, and inside the cylindrical gripping part a retaining pin extending in the radial direction of the rope drum and receiving shearing forces has been arranged, wherein the retaining pin extends through the gearwheel and partly inside the drum cover, or
• wherein the fastening device of the hoisting rope is fastened to the drum cover, and inside the cylindrical gripping part a retaining pin extending in the radial direction of the rope drum and receiving shearing forces has been arranged, wherein the retaining pin extends through the drum cover and partly inside the gearwheel.
