To select the rotator best suited to your needs, please consider this:
Applications: different types of rotators are designed to accommodate different machine types and attachments- look for a unit capable of meeting the demands of your specific tools.
Load capacities: there are two lifting capacities, STATIC and DYNAMIC.
Static –the weight a rotator can lift
Dynamic – the weight a rotator can lift and rotate.
Bearings: The rotator models with double bearings are designed to withstand both downward and upward forces. Those are used in especially challenging working conditions where extreme forces are applied to the rotator.
