摘要： An agricultural spray boom for mounting on fixed structure carried by a power driven tractor or trailer and comprising two mutually hinged sections of which the inboard section is hinged to a mounting capable of rocking on a vertical axis relative to the fixed structure and the outboard section has at its hinged end an L-shape member connected by a rigid element to near its free end with the free end of said L-shape member connected by a cable to the fixed structure above the rockable mounting, and two further cables extend from the end of the inboard section remote from the rockable mounting to the respective ends of rigid parts of different length extending oppositely of the fixed structure at a point between the connection of the first mentioned cable thereto and the position of the rockable mounting, such that the boom may be displaced between inoperative position, with its two sections adjacent one another and extending substantially vertically relative to the fixed structure, and operative position with its sections in alignment and substantially horizontal with relative folding movement of the sections being a function of the rocking of the rockable mounting and the effect of the three cables and such that should the boom in operative position encounter an obstruction it may swing with rocking of the rockable mounting and partial folding of its sections to avoid damage.
