Vogelzang Roof Units from Dedemsvaart purchased a duo Pacton double-axled open semi-trailers of the type TPD.230.L. It has a coupling weight of 12,000 kg, a maximum load on the suspension of 18,000 kg and a gross vehicle weight of 30,000 kg. Both of the semi-trailers are multifunctional in use for high volume transportation due to the lift axle on the first axle, Tridec TD steering, the maximum chassis length of 13,58 m and a relatively low chassis height of minimum 1,09 m. Notably the chassis of the semi-trailers are lower at the rear end than the front, with the chassis at the coupling being 1,29 m, at the second axle 1,15m and at the rear 1,09m in height. This is in coherence with the existing fleet of Vogelzang Roof Units. Vogelzang says that the fifth wheel heights of their other semi-trailers ranging from 1,24 m to 1,30 m, are all higher. All but two of those, are stepdeck trailers. He continuous to say that their building elements are hardly ever higher than 2,70 m, justifying their choice for open trailers at this stage to fulfil in their needs. They often have multiple packages to transport and then they place the highest package at the rear end of one of the new Pacton semi-trailers. According to Vogelzang the lift axle was also a well-considered choice because they are not a transport company, even though they tend to their own transport. They never have any return transport and therefore they drive back with only one semi-trailer axle. This purchase was the first one for Vogelzang Roof Units at Pacton Trailers in Ommen. Vogelzang points out that they came across Pacton through Oegema Transport. The new semi-trailers furthermore have steel air vessels, compact steel sideguards for the axle bogie, lashing rings in the side raves and a Groeneveld lubrication system among others.
