The installation site of the grid steel structure should take into account the characteristics of the engineering structure, site conditions, crane operating radius and other factors to plan in advance the layout of the hoisting machinery and the driving route to give full play to the efficiency of the crane to ensure the orderly progress of the hoisting.

Hoisting sequence of grid steel structure:


1. Parallel high-span and low-span roof hoisting: the high-span must be installed first, and then the low-span, which is conducive to the verticality of the high and low-span steel columns.

2. Parallel installation of large-span and small-span: The large-span must be installed first, and then the small-span installation.

3. Installations with many parallel rooms and few rooms: the ones with more rooms should be hoisted first, and then the ones with less.

4. Component hoisting In most construction situations, the vertical component is hoisted first, and then the plane component is hoisted, that is, the integrated installation method is used for hoisting.
