Roll Trailer
A roll trailer or "Mafi" is a trailer platform that requires towing by a powered vehicle. It is commonly used for the transport of heavy static goods and materials in the maritime shipping industry. Roll trailers are similar to shipping flat racks containers, however, they have a set of rear wheels. Overview Roll trailers are a common equipment used in ports and on board of roll-on/roll-off ships, to facilitate the shipping of unmovable commodities and oversize load from one port to another. Standard lengths of roll trailers are , in line with twenty-foot equivalent unit shipping containers, but can also be found in lengths of . The standard payloads of roll trailers vary from 40 to 120 tons, and the tare of the trailer varies from 7 to 10 tons. The trailer has a steel structure and a hardwood surface, plus a front pocket for towing by tugmaster gooseneck, and side handles for applying lashing hooks. Operations Goods are usually placed on roll trailers by forklift or sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trailer (vehicle)
A trailer is an unpowered vehicle Towing, towed by a powered vehicle. It is commonly used for the transport of goods and materials. There are two general categories of trailers: the full trailer and the semitrailer. A full trailer is a type of trailer whose entire weight is supported by its own wheels, with no weight transferred to the towing vehicle. In contrast, a semi-trailer is designed so that a portion of its weight is carried by its own wheels, while the remaining weight is borne by the towing vehicle. Sometimes recreational vehicles, travel trailers, or mobile homes with limited living facilities where people can camp or stay have been referred to as trailers. In earlier days, many such vehicles were towable trailers. Trailers have been used for thousands of years, predating the invention of the automobile. Before the advent of the wheel, early humans employed the concept of trailering by using drag sleds to transport goods. While the two wheel war chariot is one of the ...

Twenty-foot Equivalent Unit
The twenty-foot equivalent unit (abbreviated TEU or teu) is a general unit of cargo capacity, often used for container ships and container ports.Rowlett, 2004. It is based on the volume of a intermodal container, a standard-sized metal box that can be easily transferred between different modes of transportation, such as ships, trains, and trucks. Detailed dimensions: 20-foot and 40-foot containers The standard intermodal container is long and wide. The height of such containers is most commonly but ranges from to . Another standard container is slightly more than twice as long: , dubbed a forty-foot equivalent unit (often FEU or feu). The reason the smaller container is short of 20 feet is to allow it to be stacked efficiently with 40-foot containers. The twistlocks on a ship are set so that two standard 20-foot containers have a gap of , allowing a single 40-foot container to fit precisely on top. The 40-foot containers have found wider acceptance, as they can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Articulated Vehicles
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. Steam locomotives were sometimes articulated so the driving wheels could pivot around corners. In a broader sense, any vehicle towing a trailer (including a semi-trailer) could be described as articulated (which comes from the Latin word ''articulus'', "small joint"). In the UK, an ''articulated lorry'' is the combination of a tractor and a trailer, abbreviated to "artic". In the US, it is called a semi-trailer truck, tractor-trailer or semi-truck and is not necessarily considered articulated. Types Buses Buses are articulated to allow for a much longer bus that can still navigate within the turning radius of a normal bus. Most buses have one articulation, but some have two. Trucks In the UK, tractor unit an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Terminal Tractor
A terminal tractor, known in the United States as a shag truck, shunt truck, spotter truck, spotting tractor, yard truck, yard shifter, yard dog, yard goat, yard horse, yard mule, yard jockey, yard spotter, hostler, or mule, is a kind of semi-tractor intended to move semi-trailers within a cargo yard, warehouse facility, or intermodal facility, much like a switcher locomotive is used to position railcars. In the United Kingdom they are known as terminal lorries or terminal trucks. Some manufacturers include Terberg from The Netherlands and Kalmar Ottawa from the U.S. Characteristics Distinctions between a terminal tractor and a regular tractor unit include: *A single-person cab offset to the side of the engine. *A full-height, sliding rear door for easy access to trailer connections. *A very short wheelbase, usually with a solidly mounted rear axle. *A low-power diesel, alternative fuel engine, or electric motor usually with an automatic transmission. *A fifth-wheel co ...

Tandem
Tandem, or in tandem, is an arrangement in which two or more animals, machines, or people are lined up one behind another, all facing in the same direction. ''Tandem'' can also be used more generally to refer to any group of persons or objects working together, not necessarily in line. The English word ''tandem'' derives from the Latin adverb , meaning ''at length'' or ''finally''. It is a word play, using the Latin phrase (referring to time, not position) for English "at length, lengthwise". Horse driving When Driving (horse), driving horses, ''tandem'' refers to one horse harnessed in front of another to pull a load or Horse-drawn vehicle, vehicle. A tandem arrangement provides more pulling power than a single horse, such as for pulling a heavy load up a steep hill, out of heavy mud or snow, or pulling heavy loads on narrow tracks or through narrow gates and doorways (too wide for a pair of horses side-by-side). For example, a Brewer's van fully loaded with 25 barrels migh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crate
A crate is a large shipping container, often made of wood, typically used to transport or store large, heavy items. Steel and aluminium crates are also used. Specialized crates were designed for specific products, and were often made to be reusable, such as the "bottle crates" for milk and soft drinks. Crates can be made of wood, plastic, metal or other materials. The term ''crate'' often implies a large and strong container. Most plastic crates are smaller and are more commonly called a case (goods), case or container. Metal is rarely used because of its weight. When metal is used, a crate is often constructed as an ''open crate'' and may be termed a cage (enclosure), cage. Although a crate may be made of any material, for these reasons, the term 'crate' used alone often implies one constructed of wood. Wooden crates A wooden crate has a self-supporting structure, with or without sheathing. For a wooden container to be a crate, all six of its sides must be put in place ...

Cable Reel
A cable reel is a round, drum-shaped object such as a spool used to carry various types of electrical wires. Cable reels, which can also be termed as drums, have been used for many years to transport electric cables, fiber optic cables and wire products. Cable reels usually come in four different types, each with their own uses: wood, plywood, plastic and steel. Wooden drums Wooden drums come in three different varieties: steel-tyred for multiple use, export for sending abroad, and one-way drums for single trip use. Wooden drums can carry heavy loads and are constructed in resinous wood. Discarded wooden reels can often be obtained cheaply and are, owing to their shape, commonly used as furniture (usually coffee tables) for college students and others seeking inexpensive furnishings. Plywood drums/reels Plywood reels are used for transporting lighter loads and are a cheaper alternative to other types of drums, used extensively in the building industry and by commercial e ...

Demurrage
"Demurrage" in vessel chartering is the amount of liquidated damages owed by a charterer to a shipowner when the charterer remained in possession of the vessel for the purpose of loading and unloading ( laytime) beyond the time allowed by contract. That is, demurrage describes the charges that the charterer pays to the ship owner for its delayed operations of loading or unloading.Maritime Knowhow website: GENCON Clause 7 Officially, demurrage is a form of liquidated damages for breaching the laytime as it is stated in the governing contract (the charterparty). The demurrage sometimes causes a loss to the seller as it increases cost of the total freight. The inverse of demurrage is despatch. If the charterer requires the ...

Shipping Line
A shipping line or shipping company is a company whose line of business is ownership and operation of ships. Shipping companies provide a method of distinguishing ships by different kinds of cargo: # Bulk cargo is a type of special cargo that is delivered and handled in large quantities. # General cargo, now known as Break bulk cargo, break-bulk cargo, refers to a wide assortment of goods that may be delivered to several ports around the world. # Oil became a crucial part of the shipping industry in the early 20th century. Its use varied from lubrication for developed machinery, burning in boilers and industrial plants, as well as for operating engines. Oil is also primarily shipped by specific shipping companies as opposed to other forms of transportation. This is considered a type of special cargo. The shipping of oil has become a debated issue due to the environmental impacts of both oil spills and oil tankers. # Passenger cargo is the business of transporting people on shi ...

Crane (machine)
A crane is a machine used to move materials both vertically and horizontally, utilizing a system of a boom, hoist, wire ropes or chains, and sheaves for lifting and relocating heavy objects within the swing of its boom. The device uses one or more simple machines, such as the lever and pulley, to create mechanical advantage to do its work. Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment. The first known crane machine was the shaduf, a water-lifting device that was invented in ancient Mesopotamia (modern Iraq) and then appeared in ancient Egyptian technology. Construction cranes later appeared in ancient Greece, where they were powered by men or animals (such as donkeys), and used for the construction of buildings. Larger cranes were later developed in the Roman Empire, employing the use of human treadwheels, permitting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tractor Unit
A tractor unit, also known as a truck unit, lorry unit, power unit, prime mover, ten-wheeler, semi-tractor, semi-truck, semi-lorry, tractor cab, truck cab, lorry cab, big rig tractor, big rig truck or big rig lorry or simply a tractor, truck, lorry, semi, big rig or rig, is a characteristically heavy-duty towing engine that provides motive power for hauling a towed or trailered load. The largest such vehicles are similar to locomotives. 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. It should not be confused with a tractor-trailer which is a combination of a tractor unit and semi-trailer, whereas a ''tractor unit'' describes only the tractor portion.
