Abstract:
1. A rescue arrangement for effecting a rapid descent from a higher level to a lower level, the rescue arrangement comprising: guiding means which extend between the higher level and the lower level, carrying means which are connectable to the guiding means for carrying a person or another object from the higher level to the lower level along the guiding means, magnetic braking means located on the guiding means or the carrying means for slowing down the carrying means at least near the lower end of the guiding means, wherein the magnetic braking means comprise a series of permanent magnets, wherein at least two substantially parallel rows of permanent magnets are arranged along the guiding means near its lower end, said rows delimiting at least one slot between them and wherein the carrying means are provided with at least one braking member, which travels within the slot between the rows of magnets at the end stage of the descent of the carrying means along the guiding means, wherein the slot has an upper portion where the rows of magnets are positioned such that when the braking member has entered said upper portion of the slot, the brake effect gradually increases and peak loads can be mitigated, and wherein at the upper portion of the slot the rows of magnets have an entrance curve, such that the distance between the magnets of the two rows converges from a greater distance towards a constant width of the slot, preferably with a V-shape.
