Abstract
A boom conveyor includes a boom that carries a conveyor, a support structure, a rear pivot joint that connects a rear end of the boom to the support structure, and a pivot drive that controls pivoting movement of the boom. An operator cage is attached by a front pivot joint to a front end of the boom. A levelling system controls rotation of the operator cage about the front pivot joint. The levelling system includes a flexible cord attached to the operator cage and extending towards the rear end of the boom, and a level adjusting device that is attached to the support structure adjacent the rear end of the boom and engages an adjusting portion of the cord. During pivoting movement of the boom, the level adjusting device controls longitudinal movement of the cord relative to the boom so as to apply a levelling adjustment to the operator cage.
