You have probably seen a double trailer at some point in your life. First thought that you may have had was whether or not a double trailer set up is even safe. With the proper couplings, such as heavy duty swivel pintle hitch and fifth wheel plates, this can be a safe and more efficient way to carry cargo. You will need to look into which option is best for you by considering how much you are going to be pulling. You should keep in mind that there are laws about the weights on double trailers, with the maximum gross weight of the truck being 80,000 lbs.
There are two different coupling choices to choose from. You can choose the fifth wheel plates or you could go with the heavy duty pintle hooks. The fifth wheel design was inspired by horse-drawn carriages, allowing for the extra cargo to turn safely while in motion but to still stay strongly attached to the trailer. When maintained and serviced according to instructions, this is a very reliable way to tow cargo. Another common option is to choose the heavy duty pintle hooks. This mechanism uses safety chains and strong hooks to connect trailers. If something happens where the trailer separates, the chains help to keep the trailer attached. A fifth wheel uses a king pin safety mechanism for these purposes, and usually does a superb job of keeping the connection solid.
You may wonder if there are any advantages to using a double trailer setup for your cargo transportation. Not only is this great for the environment, it is fantastic for your company’s bottom line. Both of this is possible because you are only using one cab to pull both trailers. That means less emissions that will be given off during towing as well as less cabs that you will need. You could also look at is as you can double your products shipped through this method, with your current fleet of cabs.
There are currently some laws in place for these types of trailers, which can vary greatly between locations so it is important that you pay attention to these regulations to make sure that you stay safe and within the legal limits. The maximum weight of the vehicles in most locations is 80,000 lbs. Each method of coupling has its own limits as far as weights that can be towed. A fifth wheel plate can usually pull a maximum of 150,000 lbs., depending on the type. A heavy duty pintle hook can pull a maximum of 100,000 lbs., also depending on the model.
When you are shipping cargo, you should consider using a double trailer to do so. It is a difficult business to transport cargo because it has such a low profit margin. A double trailer makes it so that you are able to maximize your fleet of cabs in order to ship out the most cargo. Double trailers not only maximize the amount of cargo you can ship off but it can also help you save on other costs like gas. Double trailers can also help reduce the carbon footprint of your company.
