Hk Tipper Other models

With an unladen weight of 6,100 kg, payload comes to 31,900 kg, more than 80 per cent of the gross weight, a high ratio of payload to unladen weight for the class. At 9.15 m long, 2.55 m wide and with a 5.96 m wheelbase on four wheels, the trailer sits on a compact chassis built for high payload rather than large volume, as needed for sand, gravel or crushed stone.

Tipping trailers of this weight class are fitted with air brakes rather than the simple overrun brake used on light trailers. Towing it as a combination requires driving licence category C1E or CE in the EU, depending on the combined train weight. The tipping function needs its own hydraulic system with cylinder, pump and controls, which must be serviced separately from the brakes.

When buying a used tipping trailer of this kind, check the hydraulic cylinders and lines for leaks, the air brake system including brake cylinders, corrosion and wear on the bed from abrasive bulk material, and the function of the tipping lock and tailgate. Given such a high payload share, it is also worth checking the frame for twisting after frequent one-sided tipping.
