Engineered Drum Pulleys

CCI's Engineering Class Drum pulleys feature our heaviest construction available. Unlike other manufacturers, whose Engineering Class Pulleys may actually feature material construction lighter than their Mine Duty Pulley, our Engineering Class Pulleys are constructed with materials even more aggressive than the Quarry Duty product. Our Engineering Class Pulleys generally feature extra manufacturing steps such as; machining, balancing, NDT weld tests, magnetic particle tested welds and thermally stress relieving to ensure that our pulley will stand up to the most rugged application.

The CCI Engineering Class Drum Pulley can be manufactured in many designs; from rigid end disc bushed construction to turbine end disc with keyless compression hubs. The CCI Engineering Class Pulley is typically used in extremely high tension applications where performance is critical. Steel cable and high modulus fabric belt conveyors are perfect applications for the CCI Engineering Class Pulley.


Engineered Class Drum pulleys are available in four main types:
- Welded Hub Design
- Integral Hub Design
- Turbine End-Disc Design
- T-Section Design
