摘要:
A hoisting machine arrangement includes a rope drum, which has a driven gearwheel; a hoisting motor for driving the rope drum; and a gear between the hoisting motor and the rope drum. The gear has a body and a driving gearwheel, the driving gearwheel of the gear being coupled to the driven gearwheel of the rope drum. The body of the gear has a first drilling, which is arranged for fitting a shaft of the driving gearwheel; and a second drilling, which is parallel to the first drilling and arranged for fitting a shaft of the rope drum or the like. A method is disclosed for preparing a gear of a hoisting machine arrangement of this type.

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.

A rope guide of a rope drum in a crane surrounds the rope drum and keeps the hoisting rope in a spiral rope groove of the rope drum when the hoisting rope is wound into the rope groove or unwound from it. The rope guide includes a body that is made up of several parts and surrounds the rope drum; a rope guide element at a winding/unwinding point of the hoisting rope; a hoisting rope retainer for pressing the hoisting rope into the rope groove; and several guide members distributed on the circumference of the rope guide and arranged to move on a surface of the rope drum or the hoisting rope to guide the hoisting rope being wound onto the rope drum or unwound from it. The body is a chain-like entity including chain links interconnected to form a ring-like entity extending around the entire rope drum, to which entity the rope guide element, hoisting rope retainer and control members are installable.
