The hoisting device comprises a hoisting box, the bottom of the hoisting box is of a hollowed-out structure, and a steel wire rope adjusting mechanism is fixedly installed in the hollowed-out structure and used for tightening a steel wire rope and adjusting the length of the steel wire rope so as to control the installation angle of the composite floor slab; back plates in the clamping hanging plates are fixedly connected with a steel wire rope; the clamping mechanism is mounted on the back plate and the vertical plate, and is used for forcing an upper clamping plate in the clamping mechanism to generate longitudinal displacement and close to the bottom plate to clamp and fix the laminated floor slab; the auxiliary fastening mechanism is installed on the back plate in a sliding mode and fixedly connected with a steel wire rope, and the steel wire rope mechanically acts to limit movement of the clamping mechanism so that the composite floor slab can be in a clamped state all the time, the length of the steel w
