ABSTRACT:
A boom swing control device for controlling boom swing relative to a frame. Booms may be supported relative to a frame for application of material over a wide area. During an application process, the booms are subjected to various external forces which cause the booms to move or swing relative to the frame. The boom swing control device of the present invention includes first and second members operably coupled to the boom and the frame supporting the boom to control and dampen movement of the boom relative to the frame. The second member is moveably supported relative to the first member to move between an extended or excited position and a retracted normal operation position. Operation of the relative movement of the second member relative to the first member is controlled via a control assembly designed to allow the second member to move relative to the first member to an excited position upon application of a predetermined force and designed to normally bias the second member relative to the first member in a normal operation position for continued operation.
