Mechanic At Work
A mechanic is a Tradesman, skilled tradesperson who uses tools to build, maintain, or Home repair, repair Machine (mechanical), machinery, especially Engine, engines. Formerly, the term meant any member of the handicraft trades, but by the early 20th century, it had come to mean one who works with machinery. Duties Most mechanics specialize in a particular field, such as auto body mechanics, diesel mechanics, air conditioning and refrigeration mechanics, auto mechanics, bicycle mechanics, boiler mechanics, race car mechanics, aircraft mechanics, and other areas. There are also mobile mechanics who work on heavy equipment that will come to you if there is an issue that must be resolved at the location of the machine. A mechanic is typically Certification, certified by a trade association or regional government power. Mechanics may be separated into two classes based on the type of machines they work on, heavyweight and lightweight. Heavyweight work is on larger machines or heav ...

Steam Pump
A pump is a device that moves fluids (liquids or gases), or sometimes Slurry, slurries, by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy. Mechanical pumps serve in a wide range of applications such as Water well pump, pumping water from wells, aquarium filtering, pond filtering and Water aeration, aeration, in the car industry for Water cooling, water-cooling and fuel injection, in the energy industry for Pumping (oil well), pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and Penile implant, penile prosthesis. When a pump contains two or more pump mechanisms with fluid being directed to flow through them in series, it is called a ''multi-stage pump''. T ...

Trade Association
A trade association, also known as an industry trade group, business association, sector association or industry body, is an organization founded and funded by businesses that operate in a specific Industry (economics), industry. Through collaboration between companies within a Business sector, sector, a trade association coordinates public relations activities such as advertising, education, publishing and, especially, lobbying and political action. Associations may offer other services, such as producing conferences, setting industry standards, holding networking or charitable events, or offering classes or educational materials. Many associations are non-profit organizations governed by bylaws and directed by officers who are also members. (FEC: Solicitable Class of Trade Association, Library of Congress). In countries with a social market economy, the role of trade associations is often taken by employers' organizations, which also take a role in social dialogue. Political in ...

Bicycle Mechanic
A bicycle mechanic or bike mechanic is a mechanic who can perform a wide range of repairs on bicycles. Classification and wages The New York State Department of Labor describes bicycle repair as a "realistic" occupation, meaning an occupation that would be enjoyed by somebody who likes "practical, hands-on problems," dealing with "real-world materials like wood, tools, and machinery," and one that "does not involve a lot of paperwork or working closely with others." They classify it as a job that "usually requires a high school diploma and may require some vocational training or job-related course work. In some cases, an associate's or bachelor's degree could be needed. Employees in these occupations need anywhere from a few months to one year of working with experienced employees." They indicate an annual wage in the neighborhood of $25,000, but can earn up to a little more than $40,000. "In 2002, employment for bicycle repairers in New York was 360." Skills and training T ...

Watercraft
A watercraft or waterborne vessel is any vehicle designed for travel across or through water bodies, such as a boat, ship, hovercraft, submersible or submarine. Types Historically, watercraft have been divided into two main categories. *Rafts, which gain their buoyancy from the fastening together of components that are each buoyant in their own right. Generally, a raft is a "flow through" structure, whose users would have difficulty keeping dry as it passes through waves. Consequently, apart from short journeys (such as a river crossing), their use is confined to warmer regions (roughly 40° N to 40° S). Outside this area, use of rafts at sea is impracticable due to the risks of exposure to the crew. *Boats and ships, which float by having the submergeable part of their structure exclude water with a waterproof surface, so creating a space that contains air, as well as cargo, passengers, crew, etc. In total, this structure weighs less than the water that would occupy the sa ...

Aircraft
An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, in a few cases, direct Powered lift, downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, whereas unmanned aerial vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Mechanic
An aircraft mechanic, aviation mechanic or aircraft maintenance technician (AMT) is a tradesperson who carries out aircraft maintenance and repairs. AMTs inspect and perform or supervise maintenance, repairs and alteration of aircraft and aircraft systems. For a person who holds a mechanic certificate issued by the Federal Aviation Administration, the rules for certification, and for certificate-holders, are detailed in Subpart D of Part 65 of the Federal Aviation Regulations (FARs), which are part of Title 14 of the Code of Federal Regulations. The US certification is sometimes referred to by the FAA as the Aviation Maintenance Technician and is commonly referred to as the Airframe and Powerplant (A&P). Certification In the U.S, the general requirement for eligibility for a mechanic certificate include the following. The candidate must: *Be 18 or older *Be able to read, speak, and understand English fluently; *Meet the experience or educational requirement; and *Pass a set ...

Air Brake (road Vehicle)
An air brake or, more formally, a compressed-air-brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to both release the parking/emergency brakes in order to move the vehicle, and also to apply pressure to the brake pads or brake shoes to slow and stop the vehicle. Air brakes are used in large heavy vehicles, particularly those having multiple trailers which must be linked into the brake system, such as trucks, buses, trailers, and semi-trailers, in addition to their use in railroad trains. George Westinghouse first developed air brakes for use in railway service. He patented a safer air brake on March 5, 1872. Westinghouse made numerous alterations to improve his air pressured brake invention, which led to various forms of the automatic brake. In the early 20th century, after its advantages were proven in railway use, it was adopted by manufacturers of trucks and heavy road vehicles. Design and function Air br ...

Diesel Engines
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a diesel engine produces is controlled by manipulating the air-fue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garbage Truck
A garbage truck is a truck specially designed to collect municipal solid waste and transport it to a list of solid waste treatment technologies, solid waste treatment facility, such as a landfill, materials recovery facility, recycling center or transfer station (landfill), transfer station. In Australia they are commonly called rubbish trucks, or garbage trucks, while in the U.K. dustbin lorry, rubbish lorry or bin lorry is commonly used. Other common names for this type of truck include trash truck in the United States, and refuse truck, dustcart, junk truck, bin wagon or bin van elsewhere. Jargon, Technical names include waste collection vehicle and refuse collection vehicle (RCV). These vehicles are commonly seen in many urban areas. History Wagons and other means had been used for centuries to haul away solid waste. Among the first self-propelled garbage trucks were those ordered by Chiswick District Council from the Thornycroft, Thornycroft Steam Wagon and Carriage Comp ...

Dump Truck
A dump truck, known also as a dumping truck, dump lorry or dumper lorry or a dumper for short, is used for transporting materials (such as dirt, gravel, or demolition waste) for construction as well as coal. A typical dump truck is equipped with an open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front, allowing the material in the bed to be deposited ("dumped") on the ground behind the truck at the site of delivery. In the UK, Australia, South Africa and India the term applies to off-road construction plants only and the road vehicle is known as a tip lorry, tipper lorry (UK, India), tipper truck, tip truck, tip trailer or tipper trailer or simply a tipper (Australia, New Zealand, South Africa). History The dump truck is thought to have been first conceived in the farms of late 19th century western Europe. Thornycroft developed a steam dust-cart in 1896 with a tipper mechanism. The first motorized dump trucks in the United States wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Box Truck
A box truck—also known as a box van, cube van, bob truck or cube truck—is a chassis cab truck with an enclosed cuboid-shaped cargo area. On most box trucks, the cabin is separate to the cargo area; however some box trucks have a door between the cabin and the cargo area, box trucks tend to be larger than cargo vans and smaller than tractor-trailers with movable trailers. The difference between a box truck and a van is that the cargo van is a one-piece (unibody), while a box truck is created by adding a cargo box to a chassis cab. North American usage The boxes on box trucks are typically in length (the overall length of the box plus cab is even longer) and can range from Class 3 to Class 7 (12,500 lb. to 33,000 lb. gross vehicle weight rating). They often have a garage door-like rear door that rolls up. They are often used by companies transporting home appliances or furniture, or are used as moving trucks which can be rented by individuals. Ford, Dodg ...

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. Overview Tractor units typically have large-displacement diesel engines for power, durability, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
