This King is a used low loader semi-trailer — sometimes referred to as a lowbed or step-deck trailer — designed to carry exceptionally heavy and oversized loads that cannot be transported on a standard flatbed. Low loaders achieve their characteristic low deck height by dropping the load-carrying platform below the height of the axles, reducing the overall centre of gravity and allowing taller cargo to be moved within legal height restrictions. King is a well-established British manufacturer specialising in heavy-duty semi-trailers, low loaders, and specialist transport equipment, serving sectors such as construction, civil engineering, plant hire, and abnormal load haulage.
This trailer is a three-axle configuration with a gross weight rating of 44,000 kg, making it suitable for the movement of heavy plant, machinery, and construction equipment. The axles are Gigant units running on dual tyres sized 235/75 R17.5, with drum brakes and air suspension providing load stability and ride compliance. An ABS system is fitted as standard. A winch with a pulling capacity of 7,938 kg is also included, enabling self-loading of wheeled or tracked machines onto the deck.
The load bed measures 932 cm in length and 255 cm in width, with a deck height of just 93 cm from the ground — a genuinely low platform that provides substantial overhead clearance for tall cargo. The gooseneck (swan neck) extends 413 cm in length and rises to a height of 148 cm at its highest point. The kingpin coupling height is 120 cm, and the coupling pin diameter is 2 inches, conforming to standard fifth-wheel tractor units. Total trailer length reaches 1,360 cm.
Loading is facilitated by hydraulic ramps measuring 350 cm in length, fitted as two-piece driving plates, allowing vehicles and self-propelled plant to drive onto the deck under their own power. Tyre tread profiles have been recorded across all three axles: the outer left and right tyres on axle one measure 40% and 50% respectively; axle two records 40% on both sides; and axle three shows 45% on the left outer and 25% on the right outer. The trailer's serial number is SKMGTSZ44DKT11520 and it carries registration number C354831. Overall shipping dimensions are 1,360 × 255 × 282 cm. This unit is located in the Netherlands and is offered at €32,000.
