A tandem axle is a configuration on a vehicle where two axles are placed close together, usually in line. This arrangement is commonly found on trucks, trailers, and heavy equipment. The purpose of a tandem axle is to distribute the weight of the vehicle and its load over a larger area. This helps to reduce the load on each individual axle and tire, which can prolong the life of the components and the road surface.

In a tandem axle setup, the wheels on each axle are typically spaced a specific distance apart. This spacing is often regulated by weight limits for road usage. When a vehicle has a tandem axle, the total weight it can carry is usually higher than if it had a single axle. This is because the load is shared between the two axles.

Tandem axles can be rigid, meaning both axles are fixed in position, or they can be designed with some form of articulation or walking beam. Walking beam tandem axles allow for more independent movement of each axle, which helps to maintain contact with uneven surfaces and further distribute weight more evenly. This improves traction and reduces stress on the chassis. The design and implementation of tandem axles are crucial for the safe and efficient operation of heavy vehicles.
