FIELD: construction, particularly for erecting building of structural modules. ^ SUBSTANCE: device has lifting mechanism and mechanism providing horizontal movement including winch, guiding pulley and lifting means. Lifting means is made as a rotary frame pivotally installed on base mounted on upper floor panel of building to be reconstructed. Rotary frame height exceeds structural block height. Pressure roller for over-lifting prevention and rope fixation is installed on rotary frame. Rotary frame may rotate through the same angles in both directions from vertical position thereof. Rotary frame is provided with mechanism which returns frame into initial position made as spring connecting rotary frame with the base. Rope fixation with pressure roller rotary frame is rotated with winch. Additional winch may act as mechanism for performing horizontal movement. ^ EFFECT: reduced labor inputs for performing building and assembly jobs in small building site. ^ 7 cl, 8 dwg |
