Description

The centering adjustment device of the elevator safety device according to the present invention is installed so as to face each of the pair of guide rails, and lifts the elevator by a frictional force generated by sandwiching both ends of each guide rail with a rail atari. A centering adjustment device for an elevator emergency stop device that performs an emergency stop, a rail jig having the same plate thickness as a guide rail, and a bracket provided at one end of the rail jig and having an optical unit used for centering adjustment mounted thereon. When the bracket and the elevator safety device are brought into contact with each other, they are inserted into the precision holes provided on the elevator safety device side, so that the centering includes the pins for positioning the rail jig and the elevator safety device. comprising a jig, centering adjustment to equalize the gap between the rail Atari and the rail fixture using the optical unit The is intended to enable implementation.

Claims (3)
