Swivel/Rigid Combinations

You can outfit equipment with different combinations of rigid and swivel casters to meet specific needs and applications. In fact, finding the right combination can have a huge impact on stability and ergonomics. In this edition of CasterU we present some of the most common caster combinations along with the pros and cons of each.

Two Rigid, Two Swivel is generally the most popular pattern used. This combination is the most practical and the most economic design, primarily used for straight and/or long distances and can be used for most loads, depending on the total weight capacity.

The Three Swivel pattern is found on barrel dollies and small portable machines, which generally require excellent manoeuvrability. Installing a positional swivel lock on one of the casters provides additional control when needed. Because the load is distributed over only three casters, choosing casters with the right capacity is critical to performance.

The Standard Tilt Mount consists of four swivel & two rigid casters and is designed for heavy load and long platform trucks. The two rigid casters are higher than the four swivel casters. The tilt is most effective when the rigid casters are 1/8″ higher than the overall height of the swivel casters. This platform design is often used for towing applications and offers easy manoeuvrability with uneven loads and higher capacities.

Diamond Mounting uses two swivel and two rigid casters. However the rigid casters are set at the sides and the two swivel casters are set at the ends. This configuration allows the platform to pivot in the middle and turn on tight corners. It is highly manoeuvrable but less stable and therefore not recommended for ramps. The capacity is strictly dependent upon the capacity of the casters required.

Diamond Tilt Mounting is identical except the two rigid casters are 1/8″ higher than the overall height of the swivel casters. Again capacity is determined by the capacity of the casters. The tilt mount accommodates uneven loads and higher capacities.

Four Swivel casters respond instantly to directional change, making limited spaces easy to manoeuvre. This configuration is recommended for short distances. Installing a positional swivel lock on two of the casters effectively allows you to switch to a two rigid/two swivel configuration when additional control is needed.

Four Swivel, Two Rigid is designed for extremely heavy loads and long platform trucks. The two rigid casters help to distribute and reduce the load on the swivel casters, which maintain good manoeuvrability and makes steering very easy.
