Cargo Ship
A cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with crane (machine), cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped. Definitions The words ''cargo'' and ''freight'' have become interchangeable in casual usage. Technically, "cargo" refers to the goods carried aboard the ship for hire, while "freight" refers to the act of carrying of such cargo, but the terms have been used interchangeably for centuries. Generally, the modern ocean shipping business is divided into two classes: # Liner business: typically (but not exclusively) container vessels (where ...

Truck
A truck or lorry is a motor vehicle designed to transport cargo, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "Tractor unit, tractor". The majority of trucks currently in use are still powered by diesel engines, although small- to medium-size trucks with gasoline engines exist in the US, Canada, and Mexico. The market-share of ...

Tractor Unit
A tractor unit (also known as a truck unit, power unit, prime mover, ten-wheeler, semi-tractor, tractor truck, semi-truck, tractor cab, truck cab, tractor rig, truck rig or big rig or simply a tractor, truck, semi or rig) is a characteristically heavy-duty towing engine that provides motive power for hauling a towed or trailered load. These fall into two categories: heavy- and medium-duty military and commercial rear-wheel-drive semi-tractors used for hauling semi-trailers, and very heavy-duty typically off-road-capable, often 6×6, military and commercial tractor units, including ballast tractors. Overview Tractor units typically have large displacement diesel engines for power, durability, and economy; several axles; and a multi-ratio transmission (10, 13, or 18 gears) for maximum flexibility in gearing. The tractor-trailer combination distributes a load across multiple axles while being more maneuverable than an equivalently sized rigid truck. The most common traile ...

Semi-trailer
A semi-trailer is a trailer without a front axle. In the United States, the term is also used to refer to the combination of a truck and a semi-trailer; a tractor-trailer. A large proportion of a semi-trailer's weight is supported by a tractor unit, or a detachable front-axle assembly known as a dolly, or the tail of another trailer. The other portion of the semi-trailer's weight is semi-supported (half-supported) by its own wheels, which only support the rear of the semi-trailer. A semi-trailer is normally equipped with landing gear (legs which can be lowered) to support it when it is uncoupled. Many semi-trailers have wheels that are capable of being totally dismounted and are also relocatable (repositionable) to better distribute load to bearing wheel weight factors. Semi-trailers are more popular for transport than full trailers, which have both front and rear axles. Ease of backing is cited as one of the semi's chief advantages. A road tractor coupled to a semi-trailer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cargo Aircraft
A cargo aircraft (also known as freight aircraft, freighter, airlifter or cargo jet) is a fixed-wing aircraft that is designed or converted for the carriage of air cargo, cargo rather than passenger aircraft, passengers. Such aircraft usually do not incorporate passenger amenities and generally feature one or more large doors for loading cargo. Freighters may be operated by civil passenger or cargo airlines, by private individuals or by the armed forces of individual countries. Aircraft designed for cargo flight usually have features that distinguish them from conventional passenger aircraft: a wide/tall fuselage cross-section, a high-wing to allow the cargo area to sit near the ground, numerous wheels to allow it to land at unprepared locations, and a high-mounted tail to allow cargo to be driven directly into and off the aircraft. By 2015, dedicated freighters represent 43% of the 700 billion ATK (available tonne-kilometer) capacity, while 57% is carried in Airliner#Baggage ...

Cargo Spacecraft
Cargo spacecraft are robotic spacecraft that are designed to carry cargo, possibly to support space stations' operation by transporting food, propellant and other supplies. This is different from a space probes, space probe, whose missions are to conduct scientific investigations. Automated cargo spacecraft have been used since 1978 and have serviced Salyut 6, Salyut 7, Mir, the International Space Station and Tiangong program, Tiangong space station. Spacecraft Current spacecraft * the Russian Progress spacecraft—developed by Russian Federal Space Agency * the American SpaceX Dragon 2, Dragon 2 spacecraft—developed under contract from NASA by SpaceX, a private spaceflight company, the only reusable cargo spacecraft * the American Cygnus spacecraft—developed under contract from NASA by Northrop Grumman Innovation Systems, a private spaceflight company * the Chinese Tianzhou (spacecraft), Tianzhou spacecraft—developed by China Aerospace Science and Technology Corporation ...

Bristol Freighter
The Bristol Type 170 Freighter is a British twin-engine aircraft designed and built by the Bristol Aeroplane Company as both a freighter and airliner. Its best known use was as an air ferry to carry cars and their passengers over relatively short distances. A passenger-only version was also produced, known as the Wayfarer. The Freighter was developed during the Second World War, having attracted official attention from the British Air Ministry, which sought the development of a rugged vehicle capable of carrying various cargoes, including a 3-ton truck. Various changes to the design were made to accommodate their requirements, but being completed too late to participate in the conflict, the majority of sales of the Freighter were to commercial operators. In response to customer demand, an enlarged version to maximise vehicle-carrying capacity, known as the Bristol Superfreighter, was developed. Development The Bristol Type 170 was designed as a stop-gap project to provide wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Hauler
A heavy hauler is a very large transporter for moving oversize loads too large for road travel without an escort and special permit. A heavy hauler typically consists of a Ballast Tractor and hydraulic modular trailer. Some trailers may have independently steerable wheels, and several might be towed by one or more tractor units in a train. Self-propelled modular transporters (SPMT), some featuring a dozen or more self-steering axles with scores of rubber tires to spread out a load, are increasingly being manufactured. Working in coordinated teams, heavy haulers are able to carry loads exceeding 100 tons. Applications In some cases, a heavy hauler is designed and constructed to move a particular load on a one-off or short-term basis. An example is the self-propelled antenna transporter for the ALMA radio telescope project, a 28-wheeled rigid vehicle designed to carry and place radio telescope antennas up a mountain to an altitude of . Girder bridge (lowboy) trailers are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
