Centre boom section with Twinlink suspension:
(a) The boom structure floats on twin links which are supported by greasable sealed roller bearings. The angled links provide self-levelling properties without the need for springs. (b) Rubber roll stoppers provide cushioning in the event of the boom reaching full travel. (c) A dampener connected between the mounting frame and boom limits rapid roll oscillation. (d) The connection between the suspension system and the three-point linkage is via polyurethane bushes. The bushes help maximise shock absorption. (e) Poly slide strip helps transfer yaw forces whilst still allowing the boom to roll freely
