[0002] The grid roofs of large industrial plants and coal sheds are made of metal roof panels, which are usually hoisted to the roof platform in bundles by large hoisting machinery, and then manually moved to the corresponding position for installation. After the long metal roof panels are hoisted to the roof platform in bundles, due to their long length, the manual handling synchronization requirements are high, otherwise the metal roof panels will be bent, deformed, and the safety of the workers will be low; and when the roof is a sloped roof, the metal roof panels are long and there is a height difference at both ends, which makes it difficult to move them into place manually.

[0003] When renovating large industrial plants and coal shed grids, the metal roof panels need to be dismantled. The main method is to split the entire roof panel into the smallest assembly unit, and then the workers carry the smallest assembly unit of the metal roof panel to the roof platform and use large lifting machinery to lift it to the ground. This method takes a long time for workers to work at high altitudes, and the manual handling of long metal roof panels requires high synchronization, otherwise it will pose a safety risk to the workers.
