A semi-trailer truck, also known as a semi-truck, (or semi, big rig, tractor-trailer, or eighteen-wheeler) is the combination of a tractor unit and one or more semi-trailers to carry freight. A semi-trailer attaches to the tractor with a type of hitch called a fifth wheel.
Heavy Equipment Transporter System (HETS) is the name of a U.S. Army logistics vehicle transport system, the primary purpose of which is to transport the M1 Abrams tank. It is also used to transport, deploy, and evacuate armored personnel carriers, self-propelled artillery, armored bulldozers, and other heavy vehicles and equipment.
The Mighty Antar was a heavy-duty 6×4 tractor unit built by Thornycroft from the late 1940s onwards. For some decades it was the standard tank transporter of the British Army and was also used by other nations. It was powered by a shortened V8 land version of the V12 Meteor engine, derived from the Merlin and modified to run on diesel, known as the Rolls-Royce Meteorite.
Scammell Lorries Limited was a British manufacturer of trucks, particularly specialist and military off-highway vehicles, between 1921 and 1988. From 1955 Scammell was part of Leyland Motors.
An armoured recovery vehicle (ARV) is typically a powerful tank or armoured personnel carrier (APC) chassis modified for use during combat for military vehicle recovery (towing) or repair of battle-damaged, stuck, and/or inoperable armoured fighting vehicles, such as tanks and armoured personnel carriers. Most ARVs have motorized tracks, like a tank or bulldozer, enabling the ARV to operate on uneven ground. The term "Armoured Repair and Recovery Vehicle" (ARRV) is also used.
The M19 Tank Transporter was a heavy tank transporter system used in World War II and into the 1950s. It consisted of a 12-ton 6x4 M20 Diamond T Model 980 truck and companion 12-wheel M9 trailer.
An armoured vehicle-launched bridge (AVLB) is a combat support vehicle, sometimes regarded as a subtype of military engineering vehicle, designed to assist militaries in rapidly deploying tanks and other armoured fighting vehicles across gap-type obstacles, such as rivers. The AVLB is usually a tracked vehicle converted from a tank chassis to carry a folding metal bridge instead of weapons. The AVLB's job is to allow armoured or infantry units to cross craters, anti-tank ditches, blown bridges, railroad cuts, canals, rivers and ravines, when a river too deep for vehicles to wade through is reached, and no bridge is conveniently located, or sufficiently sturdy, a substantial concern when moving 60-ton tanks.
The Landkreuzer P. 1000 "Ratte" was a design for a 1000-ton tank to be used by Germany during World War II which may have been proposed by Krupp director Edward Grotte in June 1942, who had already named it "Landkreuzer". Submitted designs and drawings of the vehicle went under the names OKH Auftrag Nr. 30404 and E-30404/1, which were presented in December 1942. The tank was planned to be 1000 tonnes, being far heavier than the Panzer VIII "Maus", the heaviest tank ever built. The project gained the approval of Adolf Hitler, who had expressed interest in the development of the tank, but was cancelled by Minister of Armaments Albert Speer in early 1943.
A semi-trailer is a trailer without a front axle. The combination of a semi-trailer and a tractor truck is called a semi-trailer truck.
The Diamond T Company was an American automobile and truck manufacturer. They produced commercial and military trucks.
In road transport, an oversize load is a load that exceeds the standard or ordinary legal size and/or weight limits for a truck to convey on a specified portion of road, highway, or other transport infrastructure, such as air freight or water freight. In Europe, it may be referred to as special transport or heavy and oversized transportation. There may also be load-per-axle limits. However, a load that exceeds the per-axle limits but not the overall weight limits is considered overweight. Examples of oversize/overweight loads include construction machines, pre-built homes, containers, and construction elements.
The Scammell Pioneer was a British 6×4 tractor unit used in World War II as an artillery tractor, recovery vehicle and tank transporter.
A ballast tractor is a specially weighted tractor unit of a heavy hauler combination. It is designed to utilize a drawbar to pull or push heavy or exceptionally large trailer loads which are loaded in a hydraulic modular trailer. When feasible, lowboy-style semi-trailers are used to minimize a load's center of gravity. Typical drivetrains are 6×4 and 6×6 but also available in 8×6 and 8×8. Typical ballast tractor loads include oil rig modules, bridge sections, buildings, ship sections, and industrial machinery such as generators and turbines.
A tank transporter is a combination of a heavy tractor unit or a ballast tractor and a mating full trailer, hydraulic modular trailer or semi-trailer, used for transporting tanks and other armoured fighting vehicles. Some also function as tank recovery vehicles, the tractors of which may be armoured for protection in combat conditions.
The M25 Tank Transporter (G160) was a combination 6x6 M26 armored heavy tank transporter/tank recovery tractor and companion 40-ton M15 trailer introduced into US Army service in Europe in 1944–45. Manufactured by Pacific Car & Foundry Co., it was a substantial upgrade over the Diamond T M19 transporter/trailer duo introduced in 1940.
The SLT 56 is a heavy duty tractor unit and tank transporter currently in use by the German Army.
The Mack M123 (G792) was a 10-ton 6x6 semi-tractor introduced in 1955. The Mack M125 was a heavy cargo truck version of the M123. The M123 was used to tow tank transporter trailers while the M125 towed field artillery pieces.
The Oshkosh M1070 is a U.S. Army tank transporter tractor unit. The primary purpose of this combination for the U.S. Army is the transport of the M1 Abrams tank.
