FIELD: transport.
SUBSTANCE: set of invention relates to bolster for trailer. Bolster (1) comprises flange plate (2) and coupling ball (3). Pin (4) couples flange plate (2) and coupling ball (3). Maximum length of pin (4) is smaller in first direction (91) than in second direction (92) perpendicular to first direction (91). Flange plate (2) has the recess abutting on journal (3). Said recess increase the chances of inclination of ball draw hook (81) fitted on coupling ball (3) of coupling element (8) arranged on trailer side.
EFFECT: resistance to high power loads, simplified design.
