Overhead hoist is demolishd to crossbeam of passing a bridge

The utility model provides an overhead hoist is demolishd to crossbeam of passing a bridge, demolish when passing a bridge the crossbeam at needs, through the tip of translation dolly along the overhead pathway movement who lays of platform line code to the crossbeam of passing a bridge, the hangers of crossbeam both sides will be passed a bridge with wire rope and back as an organic whole will beconnected, on hanging the couple of handling calabash with wire rope again, then it promotes to start the handling calabash, rethread translation dolly drives the hanging beam support and moves backward, it moves backward to the assigned position to drive the crossbeam of passing a bridge promptly, the pass a bridge handling of demolising of crossbeam of completion, because hanging beam support top surface closely spaced in the boats and ships bottom surfaces to passing a bridge interval between crossbeam or the platform line code head between to the translation dolly bottom, consequently, can freely pass through the
