With conventional Low Loaders, in order to satisfy axle
load restrictions, there is limit to the payload achievable.
Generally, this is a consequence of the maximum weight that
can be imposed on the tractor unit. As a result, it is necessary
to move up a category, into Heavy Duty, Low Loaders. In the
majority of cases, these are made up of a forward bogie,
followed by a centre deck, followed by a rear bogie. In the
illustration shown, this is referred to as a 2 + 5. Numerous
combinations are available, normally only restricted by the
ability of the particular configuration to negotiate the route.
Needless to say, the deck length of A and C are determined
by the number of axles on the forward and rear bogies. In
both cases, the deck height is generally in the order of
1.00/1.15m (H2). As far as the centre deck is concerned,
the length can vary enormously, from a modest 6.00m to a
gargantuan 20.00m (and beyond), with a running height of
between 0.55 to 0.75m (H1).
Centre decks come in various shapes. Some have a narrow
profile, others a wide profile, mainly intended for larger
construction equipment i.e. excavators, dump trucks etc.
Others have a removable floor, enabling transformers (or
similar) to be carried “in suspension”. The combinations
are endless, with the choice being influenced not only by
the cargo characteristics but also national & international
regulations, combined with bridge and road restrictions.
