Elliot 30 SG – EU category O3 trailer with an 8,720 kg gross weight, 10.57 m length, 2.50 m width and a closely spaced tandem axle group
At a gross weight of 8,720 kg, the 30 SG falls into EU trailer category O3, the band between 3,500 kg and 10 tonnes, for which a compressed-air brake system is mandatory. With four wheels, the 30 SG runs a tandem-axle layout, two axles set close together.

At 10.57 m the 30 SG is a long vehicle for its weight class, its 2.50 m width sitting within the European envelope for road vehicles. The 1,310 mm figure given in the excerpt is the standard spacing between the two axles of a tandem-axle group, not the trailer's wheelbase over its full length.
Towing combinations in this weight class require at least a category C1E licence, or CE above certain gross combination masses. The tandem axle spreads the axle load across two closely spaced axles, giving a lower load per axle than a single axle at the same gross weight. The compressed-air brake acts on both axles in the group.
When buying used, a tandem-axle trailer calls for checking that the axle spacing within the group is correctly set, that braking is even across both axles, the axle bearings and spring elements on each axle, and the frame along its unusual length for this weight class for twisting and cracking. The coupling eye and its bearing are worth a look as well, particularly given the unusually long frame for a trailer of this gross weight.
