Best known for its monster chaser bins, Hawe Wester also builds a range of other trailed tackle including a line-up of walking-floor forage trailers up to 60mÑ capacity. Such luggers require appropriate running gear and, although the German firm offers a tri-axle variant, five years ago its engineering team decided it needed to look at alternative ways of spreading the load without massively increasing the drag exerted by wide, floatation rubber.
