The grid element division installation and hoisting of grid are introduced in detail.It is pointed out that during hoisting lattice apparatus is main hoisting device and door frame type apparatus is auxiliary. Besides grid must be adjusted after assembly and before bearing fixation.This technology has gained excellent economical and social effects.
