Hoisting device for fabricated laminated slab construction

The hoisting device comprises a base, a clamping sleeve and a rotary drum, a supporting rod is clamped on the inner side of the rotary drum, a cross beam is welded to the supporting rod, the top end of the supporting rod is connected with the cross beam through a pull rod, a first gear is welded to the outer side of the rotary drum, a second gear is clamped on one side of the first gear, and the second gear is connected with the clamping sleeve. And a first motor is installed at the bottom of the second gear, a first lead screw is installed at the bottom of one end of the cross beam, and a third gear is welded to the first lead screw. The hoisting device for assembly type laminated slab construction can automatically adjust the balance weight, it is guaranteed that the moments on the two sides of the supporting rod are balanced, and the situation that the hoisting device inclines due to unbalanced stress is avoided; the hoisting device is simple in structure and convenient to operate, working safety of the ho
