HOISTING DEVICE Russian patent published in 2020 - IPC B66C13/06 

FIELD: lifting devices.

SUBSTANCE: invention relates to lifting device. Device (1) comprises support trolley (3), which can move along path (2), lifting element (4) for cargo holding, lifting device (5), by means of which lifting element (4) can be lifted and lowered in vertical direction (V) relative to support trolley (3), wherein lifting device (5) comprises at least two tension elements (6, 7, 8, 9). Each tension element (6, 7, 8, 9) can be wound on support trolley (3) by means of winding device (10, 11, 12, 13). Device (1) includes the first drive device (18) for actuation of the first winding device (10, 11) and the second drive device (19) for actuation of the second winding device (12, 13). First drive device (18) comprises drive motor (21), which drives at least one shaft (23, 24) by means of bevel gear (22), shaft drives roller (14, 15) of first winding device (10, 11) by means of gear mechanism (25, 26), and second drive device (19) comprises drive motor (27), which drives roller (16, 17) of second winding device (12, 13) by means of cylindrical gear transmission, gear transmission with parallel shafts or planetary gear mechanism (28).

EFFECT: achieving ease and universality of lifting device, providing stable direction of lifting element relative to support trolley.
