Thor Trailer GLY: very heavy EU class O4 trailer with a 72,500 kg gross weight, 13,212 mm length, 11,420 kg unladen weight and 61,080 kg payload
The GLY belongs to the group of especially heavy trailers used for abnormal-load transport, above the usual 40-tonne limit for a standard articulated combination. With a gross weight of 72,500 kg the vehicle sits far above the 10-tonne threshold of EU trailer class O4, in a range that in practice calls for a special transport permit, as required for exceptionally heavy or oversized loads in most European countries.

Empty, the trailer weighs 11,420 kg, giving a payload of 61,080 kg at a gross weight of 72,500 kg. At 13,212 mm long and 2,550 mm wide, the vehicle stays within usual road dimensions, while the ratio of unladen weight to payload points to a very light yet highly load-bearing frame, typical of modular heavy-haulage trailers.
Trailers in this weight class are used for transport jobs that an ordinary articulated combination could no longer manage, such as industrial plant, large structural components or construction machinery. They carry a dual-line compressed-air braking system, mandatory already from class O3, often supplemented with additional axles to spread the high axle loads.
When buying such a heavy special-purpose trailer secondhand, checking the frame structure for deformation and cracks is decisive, since very high localised loads may have occurred over the years. The braking system and its lines should be checked for leaks, the axles and wheel bearings for play, and on trailers with several axle groups it is worth checking that the steering of the individual axles runs in sync.
