Chimney section is assembled of vertical members, which are inserted through chimney interior by alternately installing each member from each crane side. Then cranes are moved by mutual lifting thereof with the use of pulley-and-cable load hoisting system. ^ EFFECT: possibility to erect load-bearing building structures in restricted space. ^ 2 cl, 3 dwg |
