The present invention relates to a trolley coupling device (5, 6) arranged to be mounted on one end of a first trolley (1). The coupling device (5, 6) includes connection means (12) for connection to a complementary connection means (13) of a second trolley (2). The coupling device (5, 6) includes a stationary part (5) arranged to be attached to the first trolley (1) and a movable part (6) provided with the connection means (12). The movable part (6) is pivotable by a first pivot mechanism (58) around a first pivot axis (P1) in a first operation mode and pivotable by a second pivot mechanism (68) around a second pivot axis (P2) in a second operation mode. The pivot axes (P1, P2) extend vertically through the stationary part (5) and are located at a distance from each other.
According to the invention, the first (58) and second (68) pivot mechanisms and the movable part (6) are located in the same horizontal plane.
The invention also relates to a coupling system, a trolley and a use.
