The intention of a trailer coupler is to secure the trailer to the towing vehicle. It is an important piece, as the trailer couple attaches to the trailer ball. This then forms a ball and socket connection. It allows for relative movement between the towing vehicle and trailer while towing over uneven road surfaces. The trailer ball should be mounted to the rear bumper or to a drawbar, which may be removable. The drawbar secures to the trailer hitch by inserting it into the hitch receiver and pinning it.
The three most common types of couplers used are straight couplers, A-frame couplers, and adjustable couplers. Another option is bumper-pull hitches in which case draw bars can exert a large amount of leverage on the tow vehicle. This makes it harder to recover from a swerving situation (thus it may not be the safest choice depending on your trip).
Many modern trucks are powered by diesel engines, although small to medium size trucks with gas engines exist in the United States. The European Union rules that vehicles with a gross combination of mass up to 3,500 kg (7,716 lb) are also known as light commercial vehicles. Any vehicles exceeding that weight are known as large goods vehicles.
As most people have experienced, moving does involve having the appropriate materials. Some materials you might find at home or may be more resourceful to save money while others may choose to pay for everything. Either way materials such as boxes, paper, tape, and bubble wrap with which to pack box-able and/or protect fragile household goods. It is also used to consolidate the carrying and stacking on moving day. Self-service moving companies offer another viable option. It involves the person moving buying a space on one or more trailers or shipping containers. These containers are then professionally driven to the new location.
During the latter part of the 20th century, we saw a decline of the trucking culture. Coinciding with this decline was a decline of the image of truck drivers, as they became negatively stigmatized. As a result of such negativity, it makes sense that truck drivers were frequently portrayed as the "bad guy(s)" in movies.
There are certain characteristics of a truck that makes it an "off-road truck". They generally standard, extra heavy-duty highway-legal trucks. Although legal, they have off-road features like front driving axle and special tires for applying it to tasks such as logging and construction. The purpose-built off-road vehicles are unconstrained by weighing limits, such as the Libherr T 282B mining truck.
The interstate moving industry in the United States maintains regulation by the FMCSA, which is part of the USDOT. With only a small staff (fewer than 20 people) available to patrol hundreds of moving companies, enforcement is difficult. As a result of such a small staff, there are in many cases, no regulations that qualify moving companies as 'reliable'. Without this guarantee, it is difficult to a consumer to make a choice. Although, moving companies can provide and often display a DOT license.
Business routes always have the same number as the routes they parallel. For example, U.S. 1 Business is a loop off, and paralleling, U.S. Route 1, and Interstate 40 Business is a loop off, and paralleling, Interstate 40.
Without strong land use controls, buildings are too often built in town right along a bypass. This results with the conversion of it into an ordinary town road, resulting in the bypass becoming as congested as the local streets. On the contrary, a bypass is intended to avoid such local street congestion. Gas stations, shopping centers, along with various other businesses are often built alongside them. They are built in hopes of easing accessibility, while home are ideally avoided for noise reasons.
The American Association of State Highway and Transportation Officials (AASHTO) is an influential association as an advocate for transportation. Setting important standards, they are responsible for publishing specifications, test protocols, and guidelines. All which are used in highway design and construction throughout the United States. Despite its name, the association represents more than solely highways. Alongside highways, they focus on air, rail, water, and public transportation as well.
A properly fitted close-coupled trailer is fitted with a rigid tow bar. It then projects from its front and hooks onto a hook on the tractor. It is important to not that it does not pivot as a draw bar does.
The word cargo is in reference to particular goods that are generally used for commercial gain. Cargo transportation is generally meant to mean by ship, boat, or plane. However, the term now applies to all types of freight, now including goods carried by train, van, or truck. This term is now used in the case of goods in the cold-chain, as perishable inventory is always cargo in transport towards its final home. Even when it is held in climate-controlled facilities, it is important to remember perishable goods or inventory have a short life.
The FMCSA has established rules to maintain and regulate the safety of the trucking industry. According to FMCSA rules, driving a goods-carrying CMV more than 11 hours or to drive after having been on duty for 14 hours, is illegal. Due to such heavy driving, they need a break to complete other tasks such as loading and unloading cargo, stopping for gas and other required vehicle inspections, as well as non-working duties such as meal and rest breaks. The 3-hour difference between the 11-hour driving limit and 14 hour on-duty limit gives drivers time to take care of such duties. In addition, after completing an 11 to 14 hour on duty period, the driver much be allowed 10 hours off-duty.
The main purpose of the HOS regulation is to prevent accidents due to driver fatigue. To do this, the number of driving hours per day, as well as the number of driving hours per week, have been limited. Another measure to prevent fatigue is to keep drivers on a 21 to 24-hour schedule in order to maintain a natural sleep/wake cycle. Drivers must take a daily minimum period of rest and are allowed longer "weekend" rest periods. This is in hopes to combat cumulative fatigue effects that accrue on a weekly basis.
The American Association of State Highway Officials (AASHO) was organized and founded on December 12, 1914. On November 13, 1973, the name was altered to the American Association of State Highway and Transportation Officials. This slight change in name reflects a broadened scope of attention towards all modes of transportation. Despite the implications of the name change, most of the activities it is involved in still gravitate towards highways.
A circumferential route refers to a public transportation system that follows the route in the shape of a circle. Over time a nickname developed in the European Union, calling transportation networks such as these a "ring road". This is no surprise as Europe has several famous "ring roads" such as the Berliner Ring, the Brussels Ring, the Amsterdam Ring, the Boulevard Périphérique around Paris and the Leeds Inner and Outer ring roads. Other countries adopted the term as well which in turn made the name go international. Australia's Melbourne's Western Ring Road and India's Hyderabad's Outer Ring Road both adopted the name. However in Canada, the term is most commonly used, with "orbital" used to a much lesser extent.
On the contrary, the United States calls many "ring roads" as belt-lines, beltways, or loops instead. For example, the Capital Beltway around Washington, D.C. Some ring roads use terminology such as "Inner Loop" and "Outer Loop". This is, of course, for the sake of directional sense, since compass directions cannot be determined around the entire loop.
The 1950's were quite different than the years to come. They were more likely to be considered "Knights of the Road", if you will, for helping stranded travelers. In these times truck drivers were envied and were viewed as an opposition to the book "The Organization Man". Bestseller in 1956, author William H. Whyte's novel describes "the man in the gray flannel suit", who sat in an office every day. He's describing a typical office style job that is very structured with managers watching over everyone. Truck drivers represented the opposite of all these concepts. Popular trucking songs glorified the life of drivers as independent "wanderers". Yet, there were attempts to bring back the factory style efficiency, such as using tachnographs. Although most attempts resulted in little success. Drivers routinely sabotaged and discovered new ways to falsify the machine's records.
In 1984 the animated TV series The Transformers told the story of a group of extraterrestrial humanoid robots. However, it just so happens that they disguise themselves as automobiles. Their leader of the Autobots clan, Optimus Prime, is depicted as an awesome semi-truck.
The Federal-Aid Highway Amendments of 1974 established a federal maximum gross vehicle weight of 80,000 pounds (36,000 kg). It also introduced a sliding scale of truck weight-to-length ratios based on the bridge formula. Although, they did not establish a federal minimum weight limit. By failing to establish a federal regulation, six contiguous in the Mississippi Valley rebelled. Becoming known as the "barrier state", they refused to increase their Interstate weight limits to 80,000 pounds. Due to this, the trucking industry faced a barrier to efficient cross-country interstate commerce.
Moving companies that operate within the borders of a particular state are usually regulated by the state DOT. Sometimes the public utility commission in that state will take care of it. This only applies to some of the U.S. states such as in California (California Public Utilities Commission) or Texas (Texas Department of Motor Vehicles. However, no matter what state you are in it is always best to make sure you are compliant with that state
