Trailers dimensions

[steven1974]

Hi, any1 knows a good web site to obtain the different dimensions and weight capacity and characteristics of all the different types of trailers, big articulated lorries!

I've been trying to find the table of dimensions on a government website, but to no avail, so I'll just do what I can from memory!
An artic trailer can be up to 13.65m long (there are a few exceptions to this) and 2.5m wide (2.6m for refrigerated vehicles). The king pin can be no more than 12m from the rear of the trailer. The trailer must describe a track between 2 concentric circles (thats the diagram I was looking for. It basically limits how far back the wheels on the trailer are). Usual axle loads for a 3 axle trailer are about 8T per axle, but they do vary. Weight capacity is governed by gross train weight (unit + trailer). Nowadays on 6 axles you can have a gross of 44T. So say about 7.5T for unit and same for trailer(although this of course varies) gives a capacity of about 29T. Anything else, just ask and I'll do my best!!

Within the UK, there are a number of dimension restrictions.

The commonly known 13.7m long for a curtainsider is NOT a legal requirement; only a derivation of the true legislation.

Maximum Width: 2.550m (Dry Freight)

Max Swing radius from Kingpin: 2.040m
Max Length from Kingpin to back: 12.000m

There are no UK restrictions on height, although the majority of bodybuilders will not exceed 4.880m (16').

The overall length of the tractor & trailer when coupled together cannot exceed 16.5m.

Generally, a 6x2 tractor unit, pulling a tri-axle trailer can operate at 44 tonnes, whereas a 4x2 tractor unit, pulling a tandem axle trailer can operate at 38 tonnes max.

The weight imposed on the axles (trailer) is usually about 8 tonnes each, although this depends on the tyres and suspension.
