If you work in the semi-trailer industry, you’re familiar with fifth wheels. But do you know what types of fifth wheels are on the market? From stationery to sliding, we’ve got them all. Plus, besides JOST International, other brands make their own models as well. Here are the types of wheels explained.
Types of Fifth Wheels Explained: JOST International
At JOST International, we’re proud to be a world market leader and international supplier for the commercial trucking industry. We provide top-of-the-fifth wheels that accommodate various applications – sliding fifth wheels and stationary fifth wheels.
Sliding Fifth Wheels
A sliding fifth wheel is a coupler that connects the tractor unit and semi-trailer together. It features a mechanism that slides the coupler forward and backward. Sliding fifth wheels are mounted to the semi-tractor’s frame. Unlike a stationary fifth wheel, it can move along the frame rails.
Advantage: Sliding fifth wheels help transfer weight to or from the steer (front) axle when customers change trailer types or have variable loads. The number of options for customers and revenue opportunities are increased.
Stationary Fifth Wheels
Stationary mount fifth wheels, also known as fixed fifth wheels, are the original fifth wheel. These fifth wheels are ideal for applications where the semi-trailer’s kingpin setting, axle loading, and vehicle length are all constant throughout the fleet. As a rule of thumb, stationary fifth wheels are lighter than sliding mount fifth wheels.
Advantage: Stationary fifth wheels offer greater weight savings and maintenance simplicity. Customers increase revenue through greater payload and reduce operating costs with greater simplicity.
