  • Load bearing becket increases attachment options
    • The becket on this pulley is strength rated, and increases attachment options for greater versatility in rigging.
  • Prusik minding side plates allow progress capture when used in hauling systems.
    • The Gyro PM’s side plates prevent prusiks from entering the pulley body and jamming the sheave. This means they can be used in hauling systems with prusiks that capture rope progress for increased control over loads.
  • Compact design reduces system height.
    • The Gyro’s design minimizes system height for efficient and easily managed rigging that is compatible with environments where space is at a premium.
  • Roller bearings for increased efficiency
    • Roller bearings are highly efficient, reducing friction and making movement and control of loads easier
  • Fairlead flares increase efficiency
    • The pulley’s side plates are angled away from the sheave, giving a reduced bend radius and increasing efficiency if the ropes run over them
  • Hot forged body reduces wear on ropes
    • The pulley body is hot forged to reduce the number of edges on the pulley. This reduces the amount of wear ropes experience when they run over the pulley body.
