Abstract
A tensioning arrangement is provided to position belt cleaner blades relative to conveyor belt, which arrangement includes an inflatable bladder which acts to move a pivotally mounted crank, which, in turn, moves a support shaft, which carries the cleaner blades. Pressurization of the bladder causes it to expand thereby engaging the arm which moves the support shaft to a position at which the cleaner blades engage the belt to be cleaned.
