摘要： A hoisting rope arrangement in a trolley moving along a main girder of a crane and driven by an outside mechanism is provided. Both sides of the trolley are provided with successive rope pulley pairs located at a distance from one another in a longitudinal direction of the trolley and, below these, sheaves situated in a hoisting member, whereby on both sides of the trolley, a first hoisting rope is led from a first end of the main girder of the crane via one rope pulley of a first rope pulley pair down to the sheave and therefrom via an other rope pulley to a second end of the main girder, and a second hoisting rope is led from the second end of the main girder via one rope pulley of a second rope pulley pair down to the sheave and therefrom via an other rope pulley to the first end of the main girder. The arrangement employs rope pulley pairs which comprise differently sized rope pulleys but which are mounted in successive fastening points of the trolley such that they are reversed in relation to one another and such that in successive pulley pairs the differently sized rope pulleys are aligned with one another as viewed in the longitudinal direction of the trolley.
