The trailer has a load capacity of 15,8 t, so the trailer can be used in a very effective way.

The loading box has the shape of a trapezoidal bathtub, with an internal width of 2240mm at the front and 2300mm at the rear. Thanks to this construction, the unloading of materials like cut grass is not a problem.
The loading box has a hydraulic tailgate with automatic locking on the rear, and is sealed with a rubber seal.
Loading box capacity (22,6 m³) is optimally selected for transporting cereal grains. Fitted with 600 mm extensions the trailer enlarges capacity to 30,3 m3 what makes it ideal for grass or corn for silage. Thanks to the solid construction of the loading box made of walls and floor of 4mm thick sheets, rigid profiled walls and strong closed profile beams, it is possible to transport different materials in other sectors of the economy other than agriculture. The box is equipped with a front window with PLEXI and the rear wall is equipped with the grain chute.

The trailer is designed to carry 15,800 kg of heavy cargo. The chassis frame in T669XL is made of rectangular closed profiles that can carry complex loads. Such implementation prevents structure from bending and twisting and thus affects the high stability of the vehicle when working in difficult terrain. In the tandem suspension, exceptionally strong parabolic springs and axles were designed for speed of up to 40 km/h.

Load-bearing components made of high-strength steel rectangular profiles form a very stable construction.
Low center of gravity ensures high stability during driving and unloading and thus very safe operation.

PRONAR trailer T669XL is characterized by sealed loading box with a hydraulic tailgate with rubber seal.

PRONAR trailer T669XL enables the transport of loose materials and agricultural products. Thanks to very high capacity of the loading box and the possibility of using 600 mm extensions, the trailer is perfect for harvesting grass or maize for silage. Because of the solid construction of the loading box made of 4mm thick steel, it is possible to transport different materials in other sectors of the economy, e.g. in municipal or construction.

The hydraulic opening mechanism of the rear tailgate allows for opening without leaving the tractor’s cab. The automatic locking bolts of the tailgate make it safe to operate. The large opening angle of the tailgate upwards ensures trouble-free unloading and also loading of atypical materials.

The trailer uses a powerful drawbar, with a load capacity of 3000kg, cushioned with steel compression spring screws, adapted for extreme operating conditions. A D50 mm eye hitch or K80mm ball hitch can be used for connection to the tractor.

PRONAR trailer T669XL has a tandem suspension with four parabolic springs, equilibrium swing arms, with a 1360 mm wheelbase, rigid axles fitted with Ø406×120 mm drum brakes, suitable for 40km/h.

The trailer is safe thanks to its stable construction with low center of gravity and functional load box construction. The high standard of safety is also maintained by the use of rear overhang protection, metal shields over the wheels and foldable ladders and side steps.

The rear-mounted electrical socket and rear underrun protection in standard equipment simplify connection to the second trailer.

In standard equipment of the trailer’s lights are protected by metal grilles, which protect them from damage during unloading as well as dirt.

Telescopic drawbar support with two-section gear gives the possibility of ergonomic operation and precise height adjustment of the drawbar hitch.

OThe powerful telescopic cylinder, with chrome sleeves, with articulated hinges ensures reliable operation and high durability of the tipping system.

Two-layer varnish system (primer + paint) is applied to the shot blasted elements. The system with the use of two-component chemotherapeutic paint materials gives high corrosion resistance, high durability of coatings and UV resistance.

The trailer can optionally be equipped with a range of functional solutions that allow the user to tailor the vehicle to their individual needs. The trailer can be equipped with 600 mm side extensions, hydraulic straight or foldable drawbar support. The trailer can be also fitted with different braking and lighting systems and on different tyre sizes. The full range of options is listed in the optional equipment list.
