The largest Ifor Williams tipper. A 3.6m by 1.95m body is chosen for bulky, lighter loads - green waste, clearance and bark - where volume runs out before weight does, and it is a staple of plant and tool hire fleets. Formerly sold as the TT126.

- you want one that is 830kg lighter empty
The Galaxy SW345PN suits owners of inflatables and small RIBs who want the lightest trailer that still meets EU type approval, since its 500kg gross weight lets many small cars tow it without extra licence categories. Its multi-roller bed is built for a soft or RIB hull rather than a hard-chine motorboat.
