Abstract
There is disclosed an endless conveyor elevator with a foldable support frame, and which has a chassi (3), a tail conveyor section (1) pivotally connected at its tail end (2) to the chassis (3) and pivotally connected at its other end (4) to the lower end of an intermediate conveyor section (5). The upper end (6) of the intermediate conveyor section (5) is pivotally connected to one end of a head conveyor section (7). An actuator (12) is coupled with the conveyor sections to move them between an inoperative folded position, as shown in FIG. 1, to an unfolded rectilinear working position shown in FIG. 2. This movement of the conveyor sections between the inoperative and working positions is achieved by the geometry of the conveyor sections and that of a link member (9) which interconnects the chassis (3) and the head conveyor section (7).
