R55 Print E-mail


R55 Rotator Features:

  • The R55 is a hanging 'flange' rotator for use on mini-excavators, knuckleboom loaders and backhoes.
  • The built-in flange gives the rotator a flat bottom that can attach directly to a flat-topped grapple without requiring a separate flange. This design feature also allows the R55 to pass the grapple hydraulics out through ports on the bottom, or out the sides. The R55 ships with head plugs that fit both the bottom and side ports, allowing the operator to use whichever ports work best for the application.
  • Two hydraulic circuits are required to operate the rotation and clamping. However, a diverter valve is available if your equipment only has one circuit.
  • There are two ways to attach this rotator: 1) Pin directly to the boom with an "H-style" full hanger; or 2) Hang from a flat plate coupler designed for your excavator quick attach system. Click here to see an example of a hanging grapple system.
  • Seal kits and replacement parts are in stock.
