23 Jul Hoist equipment suitable for asynchronous hoist and mount of composite beam cable -stay bridge girder construction
Abstract
The utility model provides a hoist equipment suitable for asynchronous hoist and mount of composite beam cable -stay bridge girder construction, but including girder, rotatable main lifting hook, tworotating pair lifting hooks and two lugs, the middle bottom of girder is located to rotatable main lifting hook, but girder both sides bottom is located respectively to the rotating pair lifting hook,but the girder of rotatable main lifting hook district section is higher than the girder that the section was distinguished to both sides rotating pair lifting hook, girder upper end both sides be equipped with a lug respectively. The hoist induced draft fan is in cable crane machine, through external force drag the dragline draw can realize main steel beam unit and concrete bridge panel unit lift by crane after aloft horizontal rotary drum physically. The problem of composite beam cable -stay bridge main steel beam and concrete bridge panel unit with the asynchronous construction tissue thatlifts by crane the installation of hoisting system is solved. Simplify composite beam cable -stay bridge superstructure installation engineering construction process, improved the hoist and mount work efficiency greatly, shortened the hoist and mount time limit for a project, the construction is safe high -efficient, is worth further popularization the in the construction of the asynchronous hoist and mount of similar composite beam cable -stay bridge girder from now on.
