On June 14, 2023, the reporter from Trucknet learned that recently, the Ninth China International Electric Vehicle Charging and Swapping Industry Conference was grandly held in Shanghai. XCMG New Energy won the "2023 Best Technology Contribution Award in China's Charging and Swapping Industry" for its outstanding performance in green transportation, charging and swapping, etc.

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.

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.

The 5th wheel is one of the most practical devices that transforms your vehicle into a multifunctional facility. This is enabled via a hitch that is attached to your SUV, truck, RV, tractor, or lorry. Despite the complicated duties the fifth wheel serves, the system is quite simple.

Fifth-wheel trailers have always occupied a unique place in the RV market. Spacious and stylish, these models combine the size and luxury of a Class A motorhome with the convenience of a smaller travel trailer. This makes the large towables an excellent option for families, full-time RVers, or anyone looking for a comfortable camping experience.As with most types of RVs, there are literally dozens of fifth-wheel models to choose from. Most range in length from 25-45 feet, with the average trailer coming in at about 32 feet. This gives them plenty of space for not only bringing friends and family along on camping trips but all of the outdoor gear, food and beverages, and other items you’ll need for any adventure.

A fifth wheel is a home on wheels that offers the most spacious accommodations and luxurious amenities of any other type of towable RV. Unlike a motorhome, fifth wheels tow behind a heavy-duty truck, giving you more mobility than a Class A or Class C RV. Fifth wheel RVs are also a cost-effective alternative to the expensive and ongoing costs associated with hotel lodging, eating at restaurant and traveling by air.Fifth wheels are great for larger families and for those who want some privacy while camping. The roomy interiors are also perfect for hosting get-togethers with friends and family. Additionally, they offer a smoother driving experience with less sway, so they work well for longer trips.
