Choose the LM146 if...
The LM146 is a general-purpose flatbed aimed at landscaping, construction and plumbing trades that need a long, wide load bed with a high payload on a single 3500kg-braked chassis. It is used where loads are bulky or awkwardly shaped rather than plant machinery, which typically goes on the ramped GX range instead.

The U-Tilt range is Indespension's answer to ramp-loaded plant trailers, tipping the whole bed down rather than using fold-out ramps, which suits low-clearance machinery. It is generally compared with Ifor Williams' ramped GX plant trailers by hire fleets choosing between the two loading systems.
Indespension also sells a smaller U-Tilt Flatbed at 14'2" x 6'2" (4320mm x 1980mm), 3500kg GVW, 900kg unladen, 2600kg payload.
