High Performance Circle

INTRODUCTION

The High Performance Circle helps to eliminate hours of monthly planned maintenance for frequent inspection, wear strip replacement and circle shoe adjustments associated with conventional circles. Advantages include increased circle torque, performance, and improved durability. It provides a smooth, effortless rotation of blade and assists in meeting jobsite elevation tolerance.

PROVEN DESIGN

The heavy duty drive system design has been adopted from the Cat® Excavator swing drive and Cat® 14 Motor Grader worm drive. Fully-sealed bearing design replaces the open circle and drawbar reducing operator touchpoints and increasing service intervals and machine uptime.

INCREASED SERVICE INTERVALS

    
• Wear life between circle and drawbar is significantly increased
    
• Reduced likelihood of excessive clearance between circle and drawbar surface
    
• Less frequent inspections
    
• Centrally-located grease bank provides quick and easy servicing
    
• Easily accessible ring gear for quicker inspection and maintenance
    
• Circle ring can be rotated for extended replacement intervals

INCREASED OUTPUT

    
• Lower owning and operating costs through increased service intervals
    
• Reduced machine downtime
    
• No more circle shoe adjustments
    
• No more adjustments or replacement of drawbar and circle wear strips
