LOAD LIFTING DEVICE Russian patent published in 2023 - IPC B66F11/00 

FIELD: loads lifting and stabilizing devices.

SUBSTANCE: invention relates to a device for lifting and stabilizing loads. The device contains two intersecting telescopic extensions, articulated with the possibility of rotation, which are synchronously connected to each other. The connection of telescopic braces is carried out by means of five tensioning means (5, 7, 11) with positive locking. Each first tensioner (5) is positively mounted in a respective inner tube (3) of a telescopic brace with a respective inner pulley (10) and an outer pulley (6) at both ends. The second tightening means (7) with positive locking is installed horizontally between two telescopic braces on two rotating pulleys (8). The pulleys (6, 8) of the respective first tensioning means (5) and the second tensioning means (7) located on the same side are kinetically connected to each other in such a way that rotational movements can be transmitted between both pulleys (6, 8). In both outer tubes (4) another positively locking tensioner (11) is fixed, which is kinetically connected to the inner pulley (10) of the corresponding first tensioner (5).

EFFECT: prevention of unwanted oscillatory movements, slippage, as well as low wear.
