Collapsible Rotary Paddle

Model: GRP-34, GRP-35, GRP-36, GRP-37

The collapsible single and double-blade rotary paddles offer a unique solution to address safety concerns and avoid OSHA violations by preventing personnel from entering bins. The paddle collapses to fit through a standard 1-1/4” or 1-1/2” coupling, removing the need to climb into the bin to install the device. The two-vane design is best for light to medium weight materials such as feeds, seeds, grains, or materials where more surface area is needed to apply resistance to the paddles. The single-vane design is ideal for heavy materials that need minimal contact to activate an alert. The collapsible paddle is ideal for concrete silos that have thick walls or when a rotary is used to replace a capacitance probe or vibrating rod.

Applications
  • Collapses for easy installation
  • Eliminates the need to climb into the bin to install or remove the rotary 
  • Aids in compliance with OSHA standards by keeping personnel out of bins
  • One-paddle design is suitable for heavy or dense materials such as aggregates
  • Two-paddle design is suitable for light to medium weight materials such as feeds, seeds, and grains
  • Ideal for concrete silos with thick walls
Features
  • Collapses to 1-1/4" to fit through 1-1/4" or 1-1/2" NPT couplings
  • Expands to 7-3/4" when fully expanded
  • Less susceptible to damage from falling materials than solid paddles
  • One-paddle design is ideal when little contact is needed to activate alerts
  • Two-paddle design is ideal in applications where more surface area is needed to apply resistance
