ROPE COMING-OFF PREVENTING DEVICE AND GAP ADJUSTING METHOD OF ROPE COMING-OFF PREVENTING DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a rope coming-off preventing device equipped with a mechanism in which the gap between a rope guard and a rope can be easily confirmed and can be adjusted.;SOLUTION: Provided are a fixing part (11) which is fixed to a lifting machine body, an adjusting bolt (13) in which a screwing quantity can be adjusted, a pair of guide bars (14) which are attached to the fixing part through mechanical springs (15), and a contact part (12) which is attached at the tips of the pair of the guide bars, includes a configuration so as to change the gap with the fixing part by moving in parallel against the fixing part, and is arranged as facing to the rope. The contact part is under a force in the direction of pulling each other with the fixing part by the mechanical springs, and, is pushed by the tip part of the adjusting bolt against the force of pulling each other corresponding to the magnitude of the screwing quantity of the adjusting bolt to change the gap, so that the gap with the rope can be adjusted to a predetermined value.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
