Abstract
The utility model discloses a novel lifting appliance suitable for lifting all sections of steel trusses of a suspension bridge; the method is characterized in that: the hanger mainly comprises an upper part and a lower part, wherein the upper part is connected with the hanger through a pin shaft, the lower part is directly contacted with an upper beam of the steel truss girder, and the upper part and the lower part are connected by two pin shafts. When the lifting appliance is used, only the pin shaft on one side needs to be taken out, the lower part of the lifting appliance can droop under the action of self weight, and then the hand chain block is matched to realize the opening and closing of the upper part and the lower part, so that the construction is convenient. Compare this utility model's advantage with traditional hoist and mount method and lie in: (1) the hoisting lug plates do not need to be welded on the steel truss girder, so that the damage to the parent metal of the main girder is reduced, and the temporary workload is reduced. (2) The work that the conventional method needs to carry out later-stage temporary lifting lug cutting, polishing, coating and the like is avoided, and the construction period is shortened. (3) The hanger can be reused. (4) The hanger is convenient to install and dismantle.
