Dolly (trailer)
A dolly is an unpowered vehicle designed for connection to a tractor unit, truck or prime mover vehicle with strong traction power. United States Classification by axle configuration There are several types of dolly bogie: * Full trailer - 2 axle (4 wheels), with a draw bar which also controls the trailer's front axle steering. The draw bar does not take load of the full trailer. Heavy full trailer needs to have its own brakes remotely controlled by the prime mover vehicle. * Semi-trailer - 1 axle (2 wheels), without the front axle but have a landing gear. Large semi-trailer of truck size is designed for connection via the fifth wheel on the tractor unit or the semi-trailer truck. Small semi-trailer such as travel trailer and boat trailer is designed for connection via a tow hitch of a passenger vehicle. Either the fifth wheel or the tow hitch takes up to half the load of the semi-trailer. * Road train - special large dolly bogie equipped with a fifth wheel for further c ...

Tractor
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially (and originally) tillage, and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised. Etymology The word ''tractor'' was taken from Latin, being the agent noun of ''trahere'' "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term "traction motor" (1859). National variations In the UK, Ireland, Australia, India, Spain, Argentina, Slovenia, Serbia, Croatia, the Netherlands, and Germany, the word "tractor" u ...

Flatbed Trolley
A flatbed trolley a common form of freight transport in distribution environments, for moving bulk loads. Trolleys can aid in reducing effort required to move a load by allowing the user to pull or push instead of lift and carry. A very simple design offers a basic flat platform with four casters and a fixed handle which is used to either push or pull the platform with the load on the platform. Without a flat surface it becomes an open frame trolley and without a handle it is a bogie or dolly. A flatbed trolley is also sometimes called a dray, but the term dray is also used to refer to a truck with no sides. Materials The frame is usually fabricated steel. The primary flatbed surface can be constructed from wooden boards, plastic, steel or mesh. Flatbed casters can vary dramatically, made of solid rubber, air filled pneumatic or cast iron. The caster is generally the component on the flatbed trolley that limits the safe working capacity. Types There are many types of speciali ...

Boat Dolly
A boat dolly or boat trolley, also called a launching dolly or launching trolley or simply a dolly or trolley, is a device for launching small boats into the water. It is generally smaller than a boat trailer with smaller wheels and is not suitable for towing a boat on the road.

Axle Track
In automobiles (and other wheeled vehicles which have two wheels on an axle), the axle track is the distance between the hub flanges on an axle. Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. In the case of an axle with dual wheels, the centerline of the dual wheel assembly is used for the wheel track specification. Axle and wheel track are commonly measured in millimetres or inches. Common usage Despite their distinct definitions, ''axle track'', ''wheel track'' and ''track width'' are frequently used interchangeably, normally to refer to the distance between the centerline of the wheels. For a vehicle with two axles, the measurements can be expressed as ''front track'' and ''rear track''. For a vehicle with more than two axles, the axles are normally numbered for reference. Offset wheels In vehicles with offset wheels, wheel track is distinct from axle track because the centreline of the wheel is not fl ...

Baggage Cart
Baggage carts, luggage carts, luggage trolleys or trolleys are small vehicles pushed by travelers ( human-powered) to carry individual luggage, mostly suitcases. There are two major sizes: One for big luggage and one for small luggage. Carts have usually two parts for carrying luggage: A small section (basket) for carry on luggage at the same level as the handle, and a lowered large section for suitcases a small and large bags. The baggage cart was invented by supermarket entrepreneur and inventor of the shopping cart Sylvan Goldman. The carts are provided in airports, large bus stations, hotels, or train stations for transporting luggage and may be free of charge. They are sometimes owned by the operator of the establishment. In some facilities carts may be provided by a contractor such as Smarte Carte for a rental fee. Baggage carts are usually built out of steel and equipped with three or four wheels.

Mail
The mail or post is a system for physically transporting postcards, letter (message), letters, and parcel (package), parcels. A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century, national postal systems have generally been established as a government monopoly, with a fee on the article prepaid. Proof of payment is usually in the form of an adhesive postage stamp, but a postage meter is also used for bulk mailing. With the advent of email, the retronym "snail mail" was coined. Postal authorities often have functions aside from transporting letters. In some countries, a Postal Telegraph and Telephone, postal, telegraph and telephone (PTT) service oversees the postal system, in addition to telephone and telegraph systems. Some countries' postal systems allow for savings accounts and handle applications for passports. The Universal Postal Union (UPU), established in 1874, includes 192 member countries a ...

Low Loader
A lowboy (low-loader in British English, low-bed in western Canada and South Africa or float in Australia and eastern Canada) is a semi-trailer with two drops in deck height: one right after the gooseneck and one right before the wheels. This allows the deck to be extremely low compared with other trailers. It offers the ability to carry legal loads up to tall, which other trailers cannot. Lowboys are used to haul heavy equipment such as bulldozers and large industrial equipment. History The first lowboy trailer was invented in the 1920s; it featured a riveted gooseneck and solid rubber tires. The first detachable gooseneck trailer, referred to as an RGN (Removable goose neck), was invented in 1958. Types The lowboy trailer comes in several types, for a wide range of tasks. Some types are: * Fixed gooseneck (FGN): allows a longer deck length and has the lightest weight. These are lower trailers than normal, with low-profile tires, usually with drop ramps in the rear to faci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingpin (automotive Part)
The kingpin (also king-pin, king pin and k pin) is the main pivot in the steering mechanism of a car or other vehicle. The term is also used to refer to part of a fifth wheel coupling apparatus for a semi and its trailer or other load. History Originally, with the 'turntable' steering of horse-drawn wagons, this was a single pin on which the moveable axle was pivoted beneath the wagon's frame. This located the axle from side to side, but the weight of the wagon was carried on a circular wooden ring turntable surrounding this. Similar centre pivot steering was used by steam traction engines, the kingpin being mounted on the 'perch bracket' beneath the boiler. Some early cars also used centre pivot steering, although it became apparent that it was unsuitable for their increasing speeds. Ackermann steering separates the steering movement into two pivots, one near the hub of each front wheel. The beam axle between them remains fixed relative to the chassis, linked by the suspens ...
