APPARATUS TO TRANSFER LENGTHENED SUPPORT STRUCTURES IN VERTICAL POSITION Russian patent published in 1994 - IPC

FIELD: lifting-transporting mechanical engineering. SUBSTANCE: apparatus has compound pulley 3, movable block of which, using bracing wire 12, is fixed to beam 2 and braking mechanism. Before wheeled beam 9 of support structure, mainly crane, begins its turning, wheeled beam 9 is rigidly connected with post and set in vertical position. During post turning wheeled beam 9 is used as mounting tower with its lower wheel 16 fixed to prevent its longitudinal movement. In the case bracing wire 12 goes through by-pass block 8, mounted on wheeled beam 9, and fixed on braking mechanism 1. Free end of rope 4 of compound pulley 3 also goes through by-pass block 8 of wheeled beam 9, shoes of braking mechanism 1, stationary by-pass block 6 and then it is fixed to T-shaped lever of braking mechanism 1. EFFECT: apparatus is used lifting-transporting mechanical engineering. 3 dwg
