description The utility model discloses a mechanism for replacing an auxiliary hoisting wire rope of a four-beam four-rail dual-trolley bridge crane. The mechanism comprises a primary trolley mechanism and an auxiliary trolley mechanism which are mounted above and below a horizontal frame; two I-section steel bases are respectively placed on bent inner walls at the two sides of the horizontal frame; a horizontally-arranged I-section steel rail is connected to the top faces of the middle parts of the two I-section steel bases through welding; a winch with travelling wheels is mounted on the I-section steel rail in a hanging manner; and the travelling wheels horizontally run along the I-section steel rail. The mechanism has the advantages that the structure is simple, the auxiliary hoisting wire rope of the crane can be conveniently replaced through the winch, and the use is timesaving and laborsaving.
