An articulated hauler, articulated dump truck (ADT), or sometimes a dump hauler, is a very large heavy-duty type of dump truck used to transport loads over rough terrain, and occasionally on public roads. The vehicle usually has all-wheel drive and consists of two basic units: the front section, generally called the tractor, and the rear ...
An articulated vehicle is a vehicle which has a permanent or semi-permanent coupling in its construction. This coupling works as a large pivot joint , allowing it to bend and turn more sharply. There are many kinds, from heavy equipment to buses , trams and trains .
The most common combination used in Europe is a semi tractor with two axles and a cargo trailer with three axles, one of which is sometimes a lift axle, giving 5 axles and 12 wheels in total. This format is now common across Europe as it is able to meet the EU maximum weight limit of 40,000 kg (88,000 pounds) without overloading any axle.
A rigid truck and full trailer are articulated inside the cargo area length, so a semi-trailer can have a longer continuous cargo area. Because of this, a semi-trailer can haul longer objects, (logs, pipe, beams, railway track). This depends on the legislation; in some European countries, a full trailer can be as long as a semi-trailer.
Respectable diagram of the major points on a standard tractor trailer truck (or articulated lorry, if you happen to be from the other end of the pond). Admittedly not a particularly exciting image, however it does label and show and the standard points of a tractor trailer truck quite well, and that I judge is worth a shot here.
Longer Heavier Vehicles in the UK (LHV) is a large goods vehicle category in the United Kingdom.Longer Heavier Vehicles are not currently allowed to operate on UK roads because they exceed the mandated limit of six axles and 44 tonnes (43.3 long tons; 48.5 short tons) of gross weight and length of 16.5 m (54 ft 2 in) for articulated lorries, or 18.75 m (61 ft 6 in) for drawbar lorries.
In 2010, Sweden was performing tests on log-hauling trucks, weighing up to 90 t (89 long tons; 99 short tons) and measuring 30 metres (98.4 ft) and haulers for two 40 ft containers, measuring 32 metres (105 ft) in total. [31] [32] In 2015, a pilot began in Finland to test a 104-tonne timber lorry which was 33 metres (108 ft) and had 13 axles.
The M520 "Truck, Cargo, 8-ton, 4x4", nicknamed Goer, truck series was formerly the US Army’s standard heavy tactical truck before its replacement by the Oshkosh HEMTT.As trucks go, the Caterpillar-made Goer stands out due to being articulated, much wider than other trucks, and lacking suspension on the wheels.
