ELEVATOR Russian patent published in 2012 - IPC B66F3/22 

FIELD: transport.

SUBSTANCE: invention relates to carrying and lifting machine building, in particular to elevators of pantograph type and can be used in radio-engineering as mast device for accommodation various equipment, for example antennas. Elevator includes supporting frame and working platform interconnected by articulation linkage of pantograph type, two cable drums, the cables from which run over blocks of articulation linkage and are fixed on its upper links. Supporting frame is made as rectangular spatial structure of beams inside which articulation linkage is located. From inside, on upper beams of supporting frame, additional blocks are installed, also, additional blocks are installed on external sides of lower links of articulation linkage. Additional blocks on upper beams of supporting frame and on external sides of lower links of articulation linkage form system of pulleys, and cables fro cable drums to blocks of articulation linkage passes through this system of pulleys. Between blocks of articulation linkage and additional blocks of system of pulleys, bypass blocks are installed.

EFFECT: invention provides increase of elevator height.
