Abstract: The invention relates to an elevator having buckets (14) disposed at regular intervals along a drive belt (1) which co-operates with guide units (11) for guiding the belt round a path which is concave towards the said most distant points (14b) of the buckets so as to reduce the speed of the most distant points (14b) of the buckets from the belt in a loading zone.

Abstract: The buckets used for producing hoist conveyor devices according to the invention comprise at their upper and lower edges reinforcing means for the purpose of improving the rigidity of the wall of said buckets, which walls include laterally a greater convergence so as to prevent the largest passage for the lateral feeding between the walls of the upper bucket and the leading edge of the following bucket. For the purpose of modifying the positioning pitch according to the nature of the substance to be carried, the rear surface of the bucket becoming supported on the conveyor belt includes at its upper edge a bevel shoulder whose cutout is of a size to circumscribe the contour of the lower part of the bucket placed immediately above.
