As the name suggests, a semi low loader fits between a standard trailer (approximate deck height 1.50m) and a low loader (approximate deck height 1.00m) – their function is mainly twofold.
Firstly to accept cargo that is over height, which does not necessarily justify the expense of a low loader. Secondly, to accept cargo where the main characteristic is volume.
Needless to say, as with low loaders, there are many makes and styles – every manufacturer having their own strengths and weaknesses. Some semis have slightly lower decks, others are slightly higher. Some have stronger floors, others not so strong. Most are extendable, some not so extendable. The more regular semis have 3, 4 or 5 axles – more specialist semis can have as many as 10 axles.
One of the primary skills of the STG team is the ability to select the right trailer, going in the right direction, at the right time – once this has been accomplished, substantial savings in cost can arise.
Going into more depth – some semis have ramps, for self-loading/self-discharging mobile cargo – others have a canopy, similar to a Euroliner – on some, in common with many low loaders, the deck can be made wider (using a variety of techniques) – this disregards the fact that, unless the trailer is type approved for use throughout Europe, it may be restricted to a particular country/countries.
