摘要
A boom, particularly a spreading boom for suspension on an outer frame (1) of an agricultural tool and of the type in which the suspension device comprises spring suspension and shock absorbing devices in the form of a trapezoidal suspension with two substantially parallel beams of which one is connected to the outer frame (1). According to the invention the upper beam of the trapezoidal suspension is linked, each of the links (6, 7) being pivotally connected to the outer frame (1) and springs (12) being arranged on both sides of the linkage (20, 21), but on the other side of the center of suspension (8, 9). The individual spring (12) is arranged between one of said links (6, 7) and a separate beam fastened to the outer frame (1).
