This used low loader semi-trailer — sometimes referred to as a step-deck or lowboy trailer — is a heavy-duty haulage unit designed to transport oversized, tall, and heavy loads that would otherwise exceed height restrictions on a standard flatbed. Low loaders of this type are the workhorses of abnormal load transport, moving construction machinery, industrial equipment, and similarly bulky freight across road networks. Rojo Trailer is a Spanish manufacturer specialising in the design and production of semi-trailers and heavy transport solutions, serving sectors including construction, civil engineering, and heavy industry.
The trailer is the GPD4 (1+3) configuration, featuring a lowered deck platform measuring 9,250 mm in length and 2,540 mm in width. The structure is built from S500MC and S700MC high-strength low-alloy (HSLA) steel, grades chosen for their elevated yield strength, which allows the frame to handle heavy dynamic loads while keeping overall weight in check.
The axle arrangement consists of three steering SAF axles and one self-tracking axle, each rated at 12,000 kg capacity, giving a combined axle load capacity of 48,000 kg across the bogie. The suspension is a SAF pneumatic air-bag system with drum brakes and a reinforced topology, providing ride quality suited to sensitive or high-value cargo.
The gooseneck is rated at 25 tonnes and is fitted with a dual pivot position, offering flexibility in coupling and load height management. A central pit is integrated into the deck, and the trailer is equipped with a lifting table. Double ramps with hydraulic manipulation are included, measuring 2,950 mm in primary length, with secondary dimensions of 1,750 mm × 900 mm × 290 mm, enabling straightforward loading and unloading of wheeled or tracked machinery. The deck floor itself is laid with 45 mm solid natural timber planking, a standard in heavy transport for its grip, resilience, and ability to distribute point loads.
Lashing provision is substantial: ten pairs of reinforced tie-down rings rated at 10,000 kg LC each are distributed across the deck, giving operators ample securing points for machinery of varying footprints.
The seller notes that multiple factory options are available on this model, including an extendable version, hydraulic widening, a bucket arm trench, winches, and long-range hydraulic suspension. This example is located in France and is available for immediate delivery.
