INTRODUCTIONCat® Conveyor systems and conveyor products take

on the world’s toughest jobs in surface mining applica-tions. Our versatile pre-engineered solutions are mobile, modular and flexible — easily transported for use in dif ferent areas of the mine; while our engineered systems are designed to meet our customers specific mate rial handling needs. Both systems are supported by an expe-rienced team of engineers who supervise installation.

Cat Conveyor systems are designed using the latest tech-nology — from various drive configurations to advanced belt tensioning control — providing our customers with the most reliable material handling solution.

Conveyor System Capabilities● Drives with all available types of transmission and start-

ing technologies.

● Discharge units available in different configurations.

● Various take-up designs, with each model selected based on the application at hand.

● Belt storage units that feature automatic belt “pay-out” while advancing and belt storage when retreating.

● Intermediate and tail loading sections available in a number of configurations for receiving material from an extensive range of haulage equipment.

● BC100 (Pre-Engineered) and BC200 (Custom Design) models available.
