New Drive Challenge
The belts operate at full power with various loads coming back through the drive due to the density of the aggregate coming up through the vacuum hose. Short shaft lengths and low bearing loads were the design criteria.

Benefits of Gates Product

The Poly Chain® GT Carbon™ drive was designed at only 90mm wide, the narrowest drive option available within the industry.
Low shaft loads and a narrow sprocket design meant this solution was specified in future design drawings for new builds. Due to carbon fibre tensile cords this drive is zero stretch with zero maintenance.
When large loads transmit back through the drive, the non-slip Poly Chain® belt keeps driving.
