In the video, three men are working together to move a large piece of machinery up a flight of stairs. The men are all wearing hard hats and safety vests, indicating that they are likely construction workers or engineers. The machinery they are moving is green and appears to be heavy, as the men are exerting a lot of effort to lift it. The stairs they are on are made of wood and have a metal railing on one side. The walls of the building are painted green, and there is a window on the wall next to the stairs. The men are using a pulley system to lift the machinery, with one man at the top of the stairs pulling the rope while the other two are at the bottom providing support. The video is shot from an overhead angle, giving a clear view of the men's actions and the machinery they are moving.
