PROBLEM TO BE SOLVED: To provide an automatic unslinging device in which a turning function is imparted thereto, no stress is acted on a power feeding cable during turn, and a compact turning mechanism capable of obtaining a proper turning speed is provided.SOLUTION: An automatic unslinging device 1 comprises: a shackle 5 attached to a crane hook; a fixed block 7 fixed to a lower part of the shackle 5; a turning shaft 9 attached rotatably to the fixed block 7; an automatic unslinging mechanism 11 fixed to the turning shaft 9; a geared motor 13 for turning, which is fixed to the turning shaft 9; and a transmission mechanism 15 for transmitting a rotation force of the geared motor 13 for turning to the fixed block 7. By driving the geared motor 13 for turning, a driving force is transmitted to the fixed block 7 through the transmission mechanism 15, and the automatic unslinging mechanism 11 and the geared motor 13 for turning, which are fixed to the turning shaft 9, turn with the turning shaft 9.SELECTED DRAWING: Figure 4 |
