Bucket elevator including means for modifying bucket speed in the loading zone

摘要

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.
