Along the elevation line of the ceiling, draw the keel binning position line on the wall.

2) Boom installation:

First, the boom nut is equipped at one end of the boom, and then the elevation of the end of the boom is determined according to the elevation line of the roof and the keel position line of the bouncing, and the other end of the boom is connected and fixed with the floor slab according to the position of the main keel and the hanging spacing. The boom should not exceed 300 from the end of the main keel, otherwise the boom should be added. Additional booms should be set up for ceiling lamps, tuyeres and maintenance ports.
