Lifting device for relieving the hoisting cable in mine-shaft hoisting

摘要

A lifting device for hoisting cages, skips provided with man-riding decks, or counterweights in mine-shaft hoisting, for relieving the hoisting cables is distinguished by the fact that the device (2) comprises a support frame (3) which is provided with a running gear (4), can be driven onto the hoisting cage (1), the man-riding deck of the skip or the counterweight and is supported on suitable fixed supports (7). The support can also be provided via sliding bolts (5) that can be extended sideways out of the support frame (3). Arranged on the support frame (3) is a telescopic cylinder (6) which can be supplied with a pressure medium and has means for positive connection (8) with the hauling means. <IMAGE>
