A two-way drywall lift overload protection system is used to  reliably prevent overload input force or overload load from rising. Two-way dry hoisting overload protection system usually includes a telescopic dry hoist for  lifting and reducing load. The telescopic dry hoist includes a plurality of  legs, a downward lifting member, a plurality of telescopic lifting members  extending upward from the downward lifting member and an upper support, and a  winch connected to the telescopic gypsum board elevator, and connected to the  telescopic gypsum board elevator. The brake device of the winch is mechanically  connected to the sliding clutch on the telescopic gypsum board elevator to  selectively expand the lower lifting member and the plurality of telescopic  lifting members, as well as the main elongation member connected between the  winch and the sliding clutch.

 The invention comprises a lifting device for lifting ceiling panels into place flush against  the ceiling beams for installation. The device has a supporting structure for  supporting the panel and telescoping sleeves for raising and lowering the  panels. The device also has a cable and pulley connecting structure for  telescoping the sleeves with a drum or spool for winding the cable and a brake  mechanism for the drum. The supporting structure may also be pivoted at an  angle and carry thereon panels for installation against the upright wall  framework. 

 The invention includes a panel lifting device, which has at  least three telescopic slender segments, which are telescopic to each other,  and all the telescopic parts can be telescoped into non-telescopic slender  frame members. Three independent chain length segments are not directly linked  together to increase and decrease the expansion segment. The upper and lower ends  of the first segment are installed at the upper and lower ends of the first  expansion segment. The upper end of the second segment is connected with the  upper end of the non-telescopic segment, and the lower end is connected with  the lower end of the second segment. The upper end of the third segment is  connected with the upper end of the first expansion segment, and the lower end  is connected with the lower end of the third expansion segment. The  non-telescopic part has a gear transmission, and its output gear meshes with  the first chain segment to raise and reduce the first chain segment, thereby  raising and reducing the first telescopic part. The first expansion segment  lifts and lowers the second and third expansion segments simultaneously through  a chain link.
