Patented Auto-Tensioner for Tubular Drag Conveyors

April 22, 2013

Hapman’s patented auto-tensioner and take-up assembly for the tubular drag conveyor minimizes downtime, decreases costs associated with maintenance, and increases chain life by providing the proper tension over the entire system. This automatic chain tensioner adjusts the conveyor chain utilizing an air-over-oil hydraulic system. The auto-tensioner senses when tension on the chain has decreased, and automatically engages the take-up assembly to adjust the chain, ensuring optimal conveying performance with no downtime or required manual correction. A sensor at the back of the system alerts maintenance personnel when the last available adjustment has been executed. The auto-tensioner is designed specifically for challenging bulk material handling applications and is ideal for applications where maintenance is difficult or hazardous to perform.
