OUTRIGGER Russian patent published in 2020 - IPC B66C23/80 

FIELD: transport machine building.

SUBSTANCE: invention relates to lifting and transporting machine building and can be used in transport machine building, in particular, in design of outrigger support. Outrigger support comprises fixed beam (1), a telescopically movable beam (2) connected to it, and support unit (4) connected to movable beam (2). Fixed beam (2) at one end has at least one toothed rack (5). Support assembly includes support plate (29), support lever (30) and elongated rotary element (31). First end of support lever (30) is pivotally connected with support plate (29), and second end is with movable beam (2). Support lever (30) at the second end has teeth (44) interacting with at least one toothed rack (5). First end of rotary element (31) is pivotally connected to support plate (29) so that the hinge joint axis in the working position is shifted relative to the axis of the hinged connection of support lever (30) to support plate (29) towards the second end of support lever (30). Second end of rotary element (31) is pivotally connected to movable beam (2) so that the hinge joint axis in the nonworking position is shifted relative to the axis of the hinged joint of support lever (30) with movable beam (2) towards the first end of support lever (30). Support is equipped with pusher, one end of which is connected to movable beam (2), and other end is pivotally connected to eccentric, rigidly connected with support lever (30) and geometric axis of rotation of which coincides with axis of hinged joint of support lever (30) with movable beam (2).

EFFECT: higher reliability of outrigger due to possibility of its independent folding in non-operating position.
