A boom for spraying equipment comprises at least one elongate member having an outer skin over a core of a material having a lower density than the skin. The core material may occupy all of the space within the outer skin or the elongate member may be hollow, at least part of a side wall of the member being formed of an outer skin, an inner skin and core material sandwiched between the inner and outer skins. The outer skin and the core material may be metallic or non-metallic, suitably a fibre reinforced plastics material. There may be a plurality of elongate members which are mutually spaced, parallel arranged and extend in a direction lengthwise of the boom.

A boom for spraying equipment comprising a support structure adapted for mounting on a movable vehicle, first and second arms pivotally mounted on the support structure for movement between an operative position, in which the arms extend generally horizontally outwardly on respective opposite sides of the structure, and a stowed position, each arm comprising at least one boom section in which there is an elongate member extending lengthwise of the section, a plurality of spray nozzles fitted to an underside of the boom along the length thereof, and a spray line for connecting a tank on the said vehicle to the spray nozzles, each elongate member having an outer skin over a material which has a lower density than the skin, and the tensile and compressive strengths of the skin and the shear strength of the said material are sufficiently high for the boom to withstand tensile, compressive and shear forces to which it is subjected in use.
