Herringbone Wing® Pulley
Designed for applications where conventional wings suffer from excessive material lodging and wing folding.
The PPI Herringbone Wing® Pulley was designed for those applications where conventional wings suffer from excessive material lodging and wing folding. The extreme wing angles of up to 45°, use the pulleys rotation to eject material out the sides of the pulley rather than recirculating it as a conventional wing often does. These extreme angles and optimized wing height, along with a center reinforcement disc, all combine to make an incredibly strong design that excels where others fail.
