At a length of 6,920 mm and a width of 2,470 mm, the empty chassis weighs 4,890 kg, leaving a payload of 13,110 kg. This combination of a short build and high load capacity is typical of tipper trailers used on construction sites. The trailer was registered in 1993.
Short, high-capacity trailers of this type carry excavated soil, bulk material and building materials over short distances between the construction site and the tip, benefiting from a small turning circle. Because of the gross weight, the trailer runs on air brakes and needs a towing vehicle with a correspondingly high permitted trailer load.
When buying such an old tipper trailer, the condition of the tipping mechanism and hydraulic cylinders matters most, as they are heavily stressed by frequent tipping of bulk material. Equally important are frame cracks at the axle mounts, the condition of the brake drums or discs, and corrosion on the load bed, encouraged by abrasive materials such as demolition rubble. The checklist should also include the lighting, the condition of the tow eye, and confirming that the identification number matches the trailer's paperwork.
