Ifor Williams GX125HD 3.5T Plant Trailer

The Ifor Williams GX125HD (Heavy Duty) is a maximum-capacity, 12ft plant trailer purpose-built to withstand the punishing demands of transporting heavy plant, large mini-diggers, track-driven machinery, and industrial site equipment. Widely recognised as the benchmark workhorse for plant hire firms, civil engineering contractors, and groundworkers, the heavy-duty GX125HD combines a substantial 2740kg payload capacity with legendary structural resilience.

GX Series trailers are constructed from folded pre-galvanised steel sections with filled-in sides for greater flexibility. The intelligent body design allows the machine operator to safely step down from the cab directly onto the side platforms. All GX series plant models are fitted with integrated ramp and skid supports as standard. This built-in infrastructure ensures the trailer remains perfectly supported whilst being loaded, entirely eliminating the need to deploy separate manual prop stands. Equipped with an integrated front digger bucket rest, the trailer relies on the signature Ifor Williams beam axle and multi-leaf sprung suspension system to provide unparalleled stability, minimal tyre wear, and flawless tracking under full commercial load.
