The Bolt-N-Go flight system is a revolutionary assembly method for drop forged chains. Link and flight assembly is made easy by using a standard bolt and mechanical lock nut with a high strength, heat treated hollow pin. There are no circlips and no intricate assembly is required. There is no welding of flights, no need to remove chain from the conveyor for installation, and no issues with strength. Just bolt the links and the flights together. It’s easy, simple and reliable!
Bolt-N-Go is recommended for en-masse chain conveyors handling dry free-flowing products such as animal feed, corn, soybeans, wheat, canola, rice, and wood shavings.
