Hardened teeth, cut on the outside of the circle
for maximum leverage and minimum wear.
The circle is supported at six points by three
adjustable clamp plates and three adjustable
guide shoes, providing optimum circle support
and load distribution. DURAMIDE™ faced
clamp and guide shoes prevent metal-to-metal
contact and provide maximum service life.
DURAMIDE™ is a synthetic bearing material
that maximizes service life and reduces circle
system maintenance requirements.

The Volvo dual cylinder Circle Drive System
uses direct acting hydraulic power for
exceptional turning and holding capability
under full load. Circle Drive System uses
hardened drive pinions and is protected
against impact damage by an overload cushion
valve as standard equipment.
