The trailer is 12,000 mm long, 2,550 mm wide and runs on four wheels. Its wheelbase measures 6,310 mm, spreading the axles over a considerable part of the vehicle's length, which helps keep it tracking steadily. Unlike most trailers in this class, rated for 100 km/h, the TTS 620 is limited to 80 km/h, pointing to a design meant for slower site or works traffic rather than fast long-haul transport.

As an O4-class vehicle, the TTS 620 carries a dual-line compressed-air braking system, mandatory from class O3 upward. Trailers of this kind typically carry construction machinery, containers or heavy equipment between building sites, depots and works yards, where the lower top speed takes a back seat to a sturdy build and a high payload.

When buying one secondhand, check the loading deck and the lashing points for wear, since transporting construction machinery creates high localised loads. The braking system and its lines should be checked for corrosion and leaks, the four wheels for even wear, and the chassis around the axle suspension for cracks caused by repeated loading and unloading of machines.
