FRONT ELEVATOR WITH VERTICAL AND HORIZONTAL MOVEMENT OF CRADLE Russian patent published in 2019 - IPC E04G3/30 E04G3/32 

FIELD: construction.

SUBSTANCE: invention relates to construction, repair, restoration and maintenance of facades of large-size buildings and structures. Technical result is achieved by the fact that a facade elevator with a vertical and horizontal movement of the cradle, comprising a bearing frame with guiding elements and stops, located on the edge of the building roof, trolley with blocks, which can move along guide elements of bearing frame in horizontal direction, cradle with hoisting and lowering winches and friction cable drums, suspended to trolley, two branches of pull rope for horizontal movement of trolley with cradle suspended to it along guide elements, load cables for suspension and vertical displacement of cradle, system of bypass units for change of direction of branches of traction cable, equalizing unit for uniform distribution of loads on traction cable branches, tension load for pulling rope tension and creation of required friction force between friction drums and traction cable branches stored in them, at that, the load ropes, through which the cradle moves in the vertical direction, are rigidly embedded into the trolley frame and move together with the trolley and cradle in the horizontal direction, and in the cradle design two friction cable reels are provided with the possibility of their free rotation or their rigid fixation against rotation, on which in several turns the traction cable branches passed, which is passed through the equalizing unit with the tension load, which equalizes loads on traction cable branches and provides friction force between friction cable drums and traction cable branches stored in them, necessary for displacement of trolley with cradle in horizontal direction, that at alternate fixation of friction cable drums from free rotation provides operation of friction cable drum together with traction rope as traction element of trolley and, as a result, movement of trolley with hinged cradle in horizontal direction to the left or to the right, at that, cradle weight force is used as motive force to move trolley with cradle suspended thereto in horizontal direction when cradle weight moves along cargo ropes vertically downwards.

EFFECT: providing maintenance and repair of facades of buildings and structures without dismantling and subsequent installation of facade hoist at the next vertical section of the facade, since it can move horizontally along the facade.
