Problems solved by technology
In general construction sites, iron poles are usually used for hoisting, but since the level of the prefabricated stairs cannot be automatically adjusted during the hoisting process, it usually requires multiple workers to manually press the prefabricated stairs to adjust
In addition, because the lifting rope cannot be perpendicular to the prefabricated stairs, the inclined lifting rope will also generate horizontal force on the stairs during the hoisting process, which is easy to damage the prefabricated stairs during the hoisting process

The invention discloses a prefabricated stairway lifting appliance. The prefabricated stairway lifting appliance comprises a horizontal frame, a plurality of pull cables, a top part and a plurality ofconcentration cables, wherein a plurality of movable lifting lugs are arranged on the horizontal frame and are arranged in multiple rows and multiple columns, the distances between the movable lifting lugs in the same row are adjustable, and the distances between the movable lifting lugs in the same column are adjustable; the top ends of the pull cables are connected to the movable lifting lugs respectively, and the bottom ends of the pull cables are used for being connected with a prefabricated stairway; the top part is located above the horizontal frame; and the bottom ends of the concentration cables are dispersedly connected to the horizontal frame, and the upper ends of the concentration cables are connected to the top part. According to the prefabricated stairway lifting appliance,prefabricated stairways with various specifications and different suspension point positions can be lifted, convenience and quickness are achieved, and the cost of the lifting appliance is saved. Andirreversible structural damage to the prefabricated stairway in the hoisting process can be avoided.
Description
technical field [0001] The invention relates to the field of building construction equipment, in particular to a prefabricated stair spreader. Background technique [0002] During the construction of modern buildings, many buildings use prefabricated stairs to shorten the construction period. Since the prefabricated staircase is inclined as a whole, and the two ends of the prefabricated staircase are installed horizontally, it is necessary to make a special hoisting tool for hoisting operations to maintain the level of the installation nodes at both ends. In general construction sites, iron poles are usually used for hoisting, but since the level of the prefabricated stairs cannot be automatically adjusted during the hoisting process, it usually requires multiple workers to manually press the prefabricated stairs to adjust. In addition, since the lifting rope cannot be perpendicular to the prefabricated stairs, the inclined lifting rope will also generate horizontal compone...
