ABSTRACT OF THE DISCLOSURE A conveyor apparatus for elevating loose bulk material from one level to another, as in self-unloading ships, and more particularly a dual belt conveyor-elevator having a relatively long horizontal feed section, and further including a belt take-up apparatus and systm including a normal pressure mode for tensioning the outer belt of the dual belt conveyor-elevator under normal operating conditions, the belt take-up apparatus and system also including a high pressure mode which is connected in tensioning relation to the outer belt of the dual belt conveyor-elevator upon loss of motive driving power to the dual belt conveyor-elevator. The high pressure mode is capable of substantially immediately taking up slack which develops in the outer belt, particularly in the horizontal feed portion thereof, with consequent pre- vention of spillage of load material, when the driving power for the dual belt conveyor-elevator is interrupted.
