"We believe that selecting the proper shock-absorbing caster is more than just choosing a number from a catalog."

Design Considerations

Load Capacity

Most material handling vehicles rarely have equal load distribution on all wheels at the same time. The minimum and maximum intended load (including caster weight) should be determined for best stability and overall performance. Where payloads vary, a suspension system with the widest effective range of spring deflection should be used.

Mechanical Power vs. Manual

Mechanically powered vehicles normally operate at greater speed than similar vehicles drawn by hand. They are subjected to, and must withstand, much higher impact shock forces. Please consult with our engineers for proper selection.

Environment and Frequency of Use

The surface upon which your vehicle operates, the smoothness of that surface, frequency of usage and the type of payload you transport are all important factors when selecting shock isolating casters and wheel materials for your vehicle. Our engineers will assist you with this essential selection process.

Noise Control

When you require noise abatement more inline with OSHA standards. 


We strongly recommend that you consult with our engineering staff to specify shock absorbing casters for your application. Selecting the proper caster for maximum shock absorption demands that certain design elements must be reviewed and discussed.
