Problems solved by technology

[0002] At present, in the process of building construction, the traditional roof lifting devices often have the following problems: (1) The fuselage is bulky, the force is unbalanced, the bearing capacity is small, and the structural deformation is large; (2) The scope of application is limited, which is not convenient for narrow The construction of the site and the installation of heavy objects are in place; (3) the safety is poor, the sight is not good, and the operation is inconvenient; (4) the maintenance is cumbersome; (5) the wind resistance and stability are poor; (6) sensitive Poor reliability; (7) Unstable speed and inconvenient positioning
It also has problems such as poor safety, poor line of sight, inconvenient operation, cumbersome maintenance, poor wind resistance and stability, poor sensitivity and reliability, unstable speed, and inconvenient positioning.
[0005] Generally speaking, some existing roof lifting devices have the following problems: (1) The fuselage is bulky, the force is unbalanced, the bearing capacity is small, and the structural deformation is large; (2) The scope of application is limited, which is not convenient for construction in narrow sites (3) poor safety, poor sightlines, and inconvenient operation; (4) cumbersome maintenance; (5) poor wind resistance and stability; (6) relatively sensitive and reliable Poor; (7) Unstable speed and inconvenient positioning
