The present invention relates to a crane device, which prevents a wire rope from being separated in case of a high-rise crane. For the above-mentioned purpose, a slewing bearing is installed in the lower part of an upper rope sheave so that the upper rope sheave can rotate according to the winding or the unwinding of the wire rope. Therefore, a fleet angle is not restricted. The crane device of the present invention comprises a motor, which generates rotation power; a reducer, which is connected to the above-mentioned motor; a wire drum, which is connected to the above-mentioned reducer; the wire rope, which is wound around the above-mentioned wire drum; the upper rope sheave and the lower rope sheave, which are provided to distribute the load applied to the above-mentioned wire rope when a load is wound or unwound; the slewing bearing, which is installed in the lower part of the above-mentioned upper rope sheave; a magnet beam, which is connected to the above-mentioned lower rope sheave; and a wheel, which is provided to move a trolley where the motor, the reducer, the wire drum, and the upper rope sheave are installed. |
