    Lift axle on trucks and trailers: a technology that enhances transportation efficiency

    Elevated #wheel #axle is one of the important technologies used in the logistics and freight transportation industry. This #technology can be found on many trucks and trailers, as it contributes to improving the efficiency and economy of transportation operations. In this article we will explore the concept of a lifted wheel hub and how it works, as well as its benefits and scenarios in which it can be used.

    Raised wheel axle concept:

    A jacked axle is a system that allows the driver to raise or hang the rear axle of a truck or trailer when it is no longer needed. This system is usually equipped with a pneumatic or hydraulic system that can be controlled through switches or buttons in the cab. When the axle is raised, the wheels rise off the road surface, which reduces tire wear, reduces air resistance and thus increases fuel efficiency.

    How does a lifted wheel hub work:

    The process of lifting a lifted wheel axle depends on the type of system installed in the truck or trailer. In a pneumatic system, air pressure is used to raise and lower the axis. There will be a control unit that allows the driver to adjust the air level in the tires of the raised axle. Once the axle is raised, the wheels are suspended in the air without contact with the road surface.

    In a hydraulic system, hydraulic pressure is used to raise and lower the axle. Special oils and a hydraulic pump are used to achieve this goal. As with the pneumatic system, the driver can control the axle level using an in-cab controller.

    Benefits of raised wheel hub:

    Fuel Savings: One of the most important benefits of using a lifted wheel hub is fuel savings. When the axle is lifted and not in use, friction between the tires and the road surface is reduced, reducing air resistance and increasing fuel efficiency. This contributes to reducing operating costs for transport companies.

    Reduced wear: When the axle is raised, it means that the tires that are raised do not experience the normal wear caused by friction with the road. This extends the life of your tires and reduces the costs of replacing them regularly.

    Increase truck stability: When the axle is raised, it increases the stability of the truck while driving. This can be especially useful when the truck is empty or when passing through uneven roads.

    Compliance with legislation: In some places, there is legislation that specifies the maximum number of axles that must be on the ground while driving. By raising the axle, your truck or trailer can easily comply with these legislations.

    Lifted wheel hub usage scenarios:

    Driving without a load: When the truck or trailer is empty or carrying a light load, the axle can be raised to improve fuel efficiency.

    Loading and unloading: When loading or unloading, the driver may have to raise an axle that is not needed to facilitate access to low-height locations.

    Passing on uneven roads: In some cases, uneven roads are a challenge for drivers. Raising the axle can increase the stability of the truck in these situations.

    Compliance with local legislation: A raised wheel axle can be useful for complying with local road laws that specify the maximum number of axles on the ground.


    The lifted wheel axle is an important technology in the world of transportation and logistics that contributes to improving transportation efficiency and reducing operating costs. By reducing fuel consumption, wear on tires and increasing truck stability, a raised wheel axle is a valuable complement to heavy commercial vehicles. It is an important piece of equipment that contributes to achieving the best performance and economy in the world of transportation.
