Definition of Semi Trailer. Semi Trailer: a freight trailer that when attached is supported at its forward end by the fifth wheel device of the truck tractor. Semi trucks, also known as semi-trailer trucks, tractor-trailer rigs or 18 wheelers, transport over 70 percent of the goods and commodities in the United States. Using a semi truck only became possible with the development of paved roadways in the second decade of the 20th century and later massively expanding with the interstate highway system that we have today. These tractors consist of three axles with the front axles being used to steer the tractor and the rear axle and the double wheels, or dualies, propel or transfer power for the tractor, this is the drive axle.

China car transporters: Axle position looks set to move centre stageVIDEO ON THE TOPIC: Building an 18' flat trailer car carrier/hauler with dove tail project part 3
John was on his way to the jobsite. He had just purchased a new skid-steer loader, and this was going to be his first job with the new equipment. The research he did online helped him determine that this particular model would allow him to finish a job 25 percent faster than his old model.
This meant he could earn more money, which justified the purchase of the skid-steer loader and the new trailer. Little did he know that what he planned to save in efficiency, he spent on the Department of Transportation DOT ticket for being overweight on his gross vehicle weight rating GVWR. This is a common occurrence these days as more states are looking for revenue to subsidize their budgets.
Gross Vehicle Weight Rating laws are not new—authorities have just been lax about enforcing them in the past. John received his ticket because he did not understand GVWR, which is the case for many contractors. Even manufacturers have different interpretations of GVWR because the government leaves it up to each manufacturer to rate its trailers as they see fit.
The bottom line: Whatever the tag on the trailer says for Gross Vehicle Weight Rating better be higher than what the scale reads. Even though his state recognizes tongue transfer, the most he could transfer to his tow vehicle was 1, pounds.
With the trailer weighing in at 2, pounds, his total weight was 11, He was over by 1, pounds. John cannot be blamed percent because his dealer should have explained GVWR and asked John some pertinent questions about his tow vehicle.
The dealer also should have known the weight of the skid-steer loader and attachment. Trailer Gross Vehicle Weight Rating is the amount of weight the vehicle can carry. If you have a trailer that weighs 2, pounds, that weight must be included in the capacity formula to stay under the GVWR. You also must consider the addition of accessories, such as pallet fork holders, a heavier parking jack, winch and battery and other items.
Plus, you have to add the weight of any attachments you haul along with your skid loader. Even adding a planer or grapple bucket can put you over the limit.
Manufacturers have leeway in determining the GVWR of their trailers. One method is by taking the lowest component rating and calling that the GVWR. In most cases, that would be the axle or tire rating. In other cases, that would be the hub and wheel rating.
Either way, the GVWR is determined at the axle. With this method, if your axle rating is 6, pounds per axle, and you have two axles, your GVWR would be 12, pounds. If the capacity is rated at 12, pounds determined by the axle capacities , and the trailer weighs 2, pounds, they would rate their trailer at 14, GVWR.
In the first case, the capacity rating of that trailer is determined by subtracting the weight of the trailer from the GVWR of 12, pounds. If the trailer weighs 2, pounds, then the payload capacity of that model is 9, pounds. This sounds simple enough, but it actually is not.
In this case, you still have to include the 2,pound trailer weight. That weight must be transferred to the tow vehicle, but that transfer is also limited by the hitch capacity. If the hitch is only rated at 1, pounds, you cannot transfer the entire weight of the trailer to the tow vehicle. This reduces your payload capacity by the difference of 1, pounds, so the actual capacity would be 10, pounds.
This is still higher than the 9, pounds in the first example but can throw you off when you are calculating the payload capacity. This can be confusing to both dealers and consumers and, quite frankly, to DOT officers and even some state legislators. Like any law, it is open to interpretation. Next, determine the weight of everything you plan to haul on a trailer—equipment plus attachments, accessories and options.
Then, look for a trailer with a GVWR higher than the weight of everything you will be hauling. If your state recognizes weight transfer to the tow vehicle, you can take that into consideration, but if your state does not, then make sure the trailer you purchase or use has enough GVWR or, in some cases, GAWR to haul your equipment. But other manufactures might use this formula for GVWR:. Determining payload capacity and GVWR is not an easy task. You will need to determine what works in your region, and if required, you will simply need to purchase a trailer with enough Gross Vehicle Weight Rating to haul your equipment and follow the CDL requirements, or hire someone to haul your equipment for you.

Trucks are divided into light-duty, medium-duty, and heavy-duty classifications depending on their weight. Heavy-duty trucks have a gross vehicle weight of 33, lb 15, kg or more i. When a heavy-duty truck is pulling a trailer, it may have a gross combination weight of 80, lb 36, kg or more. Technically, a vehicle that carries the load by itself, without a trailer, is known as a truck, or a straight truck. Examples include certain dump trucks, concrete mixers, and garbage trucks. A vehicle that pulls the load in a trailer is known as a tractor.

In our modern drone world, where flying objects now deliver goods, it is hard to believe how far we have come in a rather short time span. When the 20th century began, horses and mules were still pulling wagons to deliver large hauls. In , E. Bennett and H. Bennet innovated the first mechanical brake to be used on a trailer and it reshaped the way people hauled goods. As the Forum newspaper quote above highlights, these two men transformed an industry built around horse-drawn trucks to a speedier means of transporting goods. The new trailer allowed one person to pick up and transport materials. In addition, much larger objects, that previous trailers could not accommodate, were able to be transported. Today, we refer to the trailer industry as the motor vehicle body and trailer manufacturing industry. Within the industry, companies manufacture any one of the following:.
