METHOD OF BRAKING ELEVATING MACHINES

摘要

FIELD: machine construction. ^ SUBSTANCE: invention relates to elevating machinery, in particular the method of their braking. In the method of two stage braking of the lifting-transporting machine the second stage of braking is switched on with some time delay for an integer plus half a period of longitudinal oscillation of the cable, caused by the switching on of the first stage. When the first and second braking stages are equal the method allows to fully liquidate longitudinal oscillations of the load cable, because in the delay time they can be accurately measured. ^ EFFECT: liquidating longitudinal oscillations of the load cable. ^ 2 dwg
