The collapsible single- and double-blade rotary paddles offer a unique solution to address safety concerns and avoiding 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 and grains or materials where more surface area is needed to apply resistance to the paddle and activate alerts. The single-vane design is ideal for heavy materials that need minimal contact to activate an alert.
Once through the wall, the paddle automatically springs back open and is ready for use. The installation of the rotary is simple and removes the need to crawl inside the bin. It can be installed by screwing the rotary into the coupling or mounting plate. The rotary can be easily removed by pulling the folding paddle back through the opening. 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.
