Cat® High Performance Circle for Motor Graders

High Performance Circle

DESCRIPTION

The High Performance Circle for Cat® Motor Graders improves machine performance, efficiency, and uptime through increased service intervals and longer life. Meeting grade elevation tolerance on your jobsite is important to reduce rework on the job. With the High Performance Circle installed on Motor Graders, operators have greater confidence in meeting grade elevation tolerance due to reduced wear between circle and drawbar.

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
