Abstract

PURPOSE: To provide an apparatus for indicating position of suspending means, in which a means for transmitting acoustic signal to the operator is provided for indicating position of suspending means, so as to help him to measure the position of the suspending means with the eyes.
CONSTITUTION: Hoist 6 driven by motor 13 is capable of raising or lowering a sheave 8 and a hook 9 at the lower end of wire rope 7 by reeling out or reeling in the wire rope 7. Length of the wire rope 7 reeled out of the drum is detected by detector 14 provided on hoist 6, and output signal of this detector 14 is afforded to operating means 15, where acoustic signal is produced directly. Or otherwise, memory 16 reproduces acoustic signal by selecting a record corresponding to the output signal of said detector. Singal given by the operating means 15 or memory 16 is converted into acoustic signal by sound producing means 17 in operator's cabin 12 and transmitted to the operator, thus indicating him the position of suspending means.
