Application boundaries of multichannel friction pulleys

Abstract
A specific feature of a hoisting system with a friction pulley is the existence of a minimum hoisting height limit, which is provided by the drive pulley under the conditions of rope sliding. The upper limit on the lifting height is determined by the prescribed strength of the ropes. The article presents the main dependences determining the area of use of multi-rope friction pulleys in the range of permissible lifting depths, and also gives a graph-analytical method of calculation of this system for the case of application of equilibrium tail ropes.
