Technical Park RP22PM: a heavy modular EU class O4 trailer from 2022 with a 36,000 kg gross weight, twelve wheels and a low payload share
The RP22PM from Technical Park is a trailer built in 2022. With a gross weight of 36,000 kg it falls into EU trailer class O4, the heavy trailers above 10 tonnes towed behind suitably rated tractor units in heavy haulage and construction traffic. Twelve wheels point to a multi-axle build typical of modular and low-loader trailers.

An unladen weight of 31,310 kg leaves only 4,690 kg of payload against the 36,000 kg gross weight, a low share for this size class. Such a heavy chassis with comparatively little payload is typical of trailers that themselves serve as a stable, low load-bearing structure for very heavy, compact cargo. The small 1,244 mm gap between axles within the axle group points to closely set axles, as used on multi-axle units.
Heavy modular and low-loader trailers with twelve wheels typically carry construction machinery, industrial plant or other compact heavy loads, where a load-bearing, low frame matters more than a high payload. Because the gross weight exceeds 10 tonnes, such trailers are normally fitted with air brakes, need a towing vehicle rated for a correspondingly high trailer weight, and usually require a permit for abnormal loads.
On a heavy multi-axle trailer like this, check first that all twelve wheels track evenly, since closely set axle groups take particular strain in corners. Also check the air brake system on all axles, the condition of the axle bearings in the closely set group, and look closely for cracks on the cross members of the low frame.
