A boat trailer is a trailer designed to launch, retrieve, carry and sometimes store boats.
Prior to the 20th century, freight was generally transported overland via trains and railroads. During this time, trains were essential, and they were highly efficient at moving large amounts of freight. But, they could only deliver that freight to urban centers for distribution by horse-drawn transport. Though there were several trucks throughout this time, they were used more as space for advertising that for actual utility. At this time, the use of range for trucks was quite challenging. The use of electric engines, lack of paved rural roads, and small load capacities limited trucks to most short-haul urban routes.
Beginning the the early 20th century, the 1920's saw several major advancements. There was improvement in rural roads which was significant for the time. The diesel engine, which are 25-40% more efficient than gas engines were also a major breakthrough. We also saw the standardization of truck and trailer sizes along with fifth wheel coupling systems. Additionally power assisted brakes and steering developed. By 1933, all states had some form of varying truck weight regulation.
The decade of the 70s saw the heyday of truck driving, and the dramatic rise in the popularity of "trucker culture". Truck drivers were romanticized as modern-day cowboys and outlaws (and this stereotype persists even today). This was due in part to their use of citizens' band (CB) radio to relay information to each other regarding the locations of police officers and transportation authorities. Plaid shirts, trucker hats, CB radios, and using CB slang were popular not just with drivers but among the general public.
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.
Trailer stability can be defined as the tendency of a trailer to dissipate side-to-side motion. The initial motion may be caused by aerodynamic forces, such as from a cross wind or a passing vehicle. One common criterion for stability is the center of mass location with respect to the wheels, which can usually be detected by tongue weight. If the center of mass of the trailer is behind its wheels, therefore having a negative tongue weight, the trailer will likely be unstable. Another parameter which is less commonly a factor is the trailer moment of inertia. Even if the center of mass is forward of the wheels, a trailer with a long load, and thus large moment of inertia, may be unstable.
In some states, a business route is designated by adding the letter "B" after the number instead of placing a "Business" sign above it. For example, Arkansas signs US business route 71 as "US 71B". On some route shields and road signs, the word "business" is shortened to just "BUS". This abbreviation is rare and usually avoided to prevent confusion with bus routes.
Truckload shipping is the movement of large amounts of cargo. In general, they move amounts necessary to fill an entire semi-trailer or inter-modal container. A truckload carrier is a trucking company that generally contracts an entire trailer-load to a single customer. This is quite the opposite of a Less than Truckload (LTL) freight services. Less than Truckload shipping services generally mix freight from several customers in each trailer. An advantage Full Truckload shipping carriers have over Less than Truckload carrier services is that the freight isn't handled during the trip. Yet, in an LTL shipment, goods will generally be transported on several different trailers.
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.
Advocation for better transportation began historically in the late 1870s of the United States. This is when the Good Roads Movement first occurred, lasting all the way throughout the 1920s. Bicyclist leaders advocated for improved roads. Their acts led to the turning of local agitation into the national political movement it became.
As the American Interstate Highway System began to expand in the 1950's, the trucking industry began to take over a large market share. That is, a large share of the transportation of goods throughout the country. Before this era, trains had been relied on to transport the bulk of the goods cross country or state to state. The Interstate Highway System was influential as it allows for merchandise to travel door to door with ease. Since then, truckload carriers have taken advantage of the interstate system, especially when performing a long distance move. Typically, they bring the merchandise from one distribution center of the country to another part of the country. The increase in truckload freight transportation has reduced the time it takes to transport the goods. Whether the freight was manufactured or produced for the different areas internationally, the time it takes to transport goods has decreased dramatically.
There are many different types of trailers that are designed to haul livestock, such as cattle or horses. Most commonly used are the stock trailer, which is enclosed on the bottom but has openings at approximately. This opening is at the eye level of the animals in order to allow ventilation. A horse trailer is a much more elaborate form of stock trailer. Generally horses are hauled with the purpose of attending or participating in competition. Due to this, they must be in peak physical condition, so horse trailers are designed for the comfort and safety of the animals. They're typically well-ventilated with windows and vents along with specifically designed suspension. Additionally, horse trailers have internal partitions that assist animals staying upright during travel. It's also to protect other horses from injuring each other in transit. There are also larger horse trailers that may incorporate more specialized areas for horse tack. They may even include elaborate quarters with sleeping areas, bathroom, cooking facilities etc.
The Federal Motor Carrier Safety Administration (FMCSA) issues Hours of Service regulations. At the same time, they govern the working hours of anyone operating a commercial motor vehicle (CMV) in the United States. Such regulations apply to truck drivers, commercial and city bus drivers, and school bus drivers who operate CMVs. With these rules in place, the number of daily and weekly hours spent driving and working is limited. The FMCSA regulates the minimum amount of time drivers must spend resting between driving shifts. In regards to intrastate commerce, the respective state's regulations apply.
The Federal Highway Administration (FHWA) is a division of the USDOT specializing in highway transportation. The agency's major influential activities are generally separated into two different "programs". The first is the Federal-aid Highway Program. This provides financial aid to support the construction, maintenance, and operation of the U.S. highway network. The second program, the Federal Lands Highway Program, shares a similar name with different intentions. The purpose of this program is to improve transportation involving Federal and Tribal lands. They also focus on preserving "national treasures" for the historic and beatific enjoyment for all.
Released in 1998, the film Black Dog featured Patrick Swayze as a truck driver who made it out of prison. However, his life of crime continued, as he was manipulated into the transportation of illegal guns. Writer Scott Doviak has described the movie as a "high-octane riff on White Line Fever" as well as "a throwback to the trucker movies of the 70s".
The most basic purpose of a trailer jack is to lift the trailer to a height that allows the trailer to hitch or unhitch to and from the towing vehicle. Trailer jacks may also be used for the leveling of the trailer during storage. To list a few common types of trailer jacks are A-frame jacks, swivel jacks, and drop-leg jacks. Other trailers, such as horse trailers, have a built-in jack at the tongue for this purpose.
In order to load or unload bots and other cargo to and from a trailer, trailer winches are designed for this purpose. They consist of a ratchet mechanism and cable. The handle on the ratchet mechanism is then turned to tighten or loosen the tension on the winch cable. Trailer winches vary, some are manual while others are motorized. Trailer winches are most typically found on the front of the trailer by towing an A-frame.
In the United States and Canada, the cost for long-distance moves is generally determined by a few factors. The first is the weight of the items to be moved and the distance it will go. Cost is also based on how quickly the items are to be moved, as well as the time of the year or month which the move occurs. In the United Kingdom and Australia, it's quite different. They base price on the volume of the items as opposed to their weight. Keep in mind some movers may offer flat rate pricing.
