JOST International has been manufacturing fifth wheel coupling devices since 1956. In fact, we submitted the patent for the first-ever steel cast fifth wheel coupling. As a leading manufacturer of fifth wheels, we want to make sure that anyone in the industry, new or experienced, has access to helpful, informative content about all of our components. With that goal in mind, we’re tackling a popular question from those new to the semi-truck and industrial transportation industry: “how does a fifth wheel work on a semi?”.

Coupling is when the truck’s 5th wheel locking jaws lock around the trailer’s kingpin. This connection allows the truck to haul the trailer. Proper coupling techniques can prevent unnecessary damage to the equipment.

To operate a tractor-trailer safely, proper coupling and uncoupling techniques are essential. Any driver who is unfamiliar with the correct coupling and uncoupling techniques is asking for disaster. Improper connection may lead to cab and freight damage, litigation, penalties, fallen trailers, damaged air, and electrical lines, and other significant repercussions. These effects may always be avoided. To ensure that the operation is always carried out in the same precise order, every time, experienced drivers are expected to be knowledgeable about safe coupling and uncoupling procedures. Before trying a coupling or uncoupling technique, be familiar with the protocols and the risks.

For years, manual lever-style fifth wheels were the go-to product in the semi-trailer business. Today, air-release fifth wheels have been introduced, providing convenience. So, what’s the difference between manual and air-release fifth wheels, and which option is best for you based on your application? We’re here to tell you all about it.

When coupling the proper position of the fifth wheel is a crucial aspect to consider for safe and efficient towing. The fifth wheel is the connecting point between a towing vehicle and a trailer, and its correct positioning can greatly impact the stability and handling of the entire setup. In this article, we will explore the importance of properly positioning the fifth wheel and discuss the factors to consider when coupling.

Some of the differences between gooseneck hitches and 5th wheel hitches are the coupling mechanism, the level of invasiveness in the truck bed, overall cost and the types of trailers typically pulled by each hitch.Despite these difference, gooseneck hitches and 5th wheel hitches have many similarities. Both are used for towing heavy-duty trailers, and both require a pickup truck for installation, mounting into the truck bed, over the rear axle.

A fifth wheel is a part that almost anyone in industrial trucking is familiar with. We know it works to connect the semi truck tractor and trailer, and if you’ve been in the business for a while, you might even be familiar with a few of the key features that are nice to have in top-of-the-line models.But when there are so many options to choose from on the market today, it can be helpful to know what you truly need to have and what options are add-ons. Since all fifth wheels are manufactured a little differently, we’re going to dive into the 5 essential parts of a fifth wheel. This should give you the information you need to find the best fifth wheel for your unique application.

The biggest pro associated with the fifth wheel is the maneuverability that comes with a free front axis. This feature that the fifth wheel hitch offer allows you to turn your car or truck while your trailer follows swiftly behind you.This design makes transportation through cities and highways much less nerve-racking since you are not dealing with a massive, wide-turning vehicle.In terms of backing up, neither the motorhome or trailer proves uniquely entertaining. Both bring their own sets of problems. A motorhome is massive and wide turning, while a trailer goes the opposite way you want it.

The fifth wheel part that most commonly requires repair is the top plate. The top plate is a horseshoe-shaped plate that’s attached to the main frame of the vehicle. It offers trailers and cargo a secure connecting point for heavy loads. Why is the top plate the most common fifth wheel repair? It’s under intense stress while in use. This high stress can damage the plate and normal wear can break down internal, smaller components like lock jaws and cushion ring inserts, bushings, release handles, and more to the point of replacement. You may also struggle with fifth wheel top plate troubles if your coupling attempts aren’t in compliance with JOST’s Operating Instructions or the industry standard TMC RMP-654.All of these possibilities show why following standards and being proactive about inspections and maintenance is key.

The passenger side landing jack on our Keystone Cougar fifth wheel suffered a major failure last week. I was in the process of jacking the trailer off the truck when I heard and felt a loud clunk. In fact, my wife who was inside setting things up immediately looked out the window and ask “What the heck was that?”. “Not sure” I replied, but I knew something was not right with the jacks.I decide to retract them again and that’s when I saw the passenger side landing leg was not lifting up!  Luckily I was still hooked to the truck so I set to work removing the faulty landing leg to try and determine the issue. Removing the trailers landing leg was pretty straight forward involving undoing just a few bolts, its foot pad and locking pin assembly. In no time I had the whole leg out.
