Abstract
A retractable and extendable material loader that directs material onto a conveying surface of a belt conveyor has a retractable and extendable tubular length where the length of the loader is extended to direct material through the loader onto the conveyor, and a length of the loader is retracted when the loader is not directing material onto the conveyor to provide adequate clearance for material loaded onto the conveyor by another loader located upstream of the retractable and extendable loader. The apparatus provides improved environmental conditions over the current art, improved health and safety conditions of personnel over the current art, and improved operational safety conditions in respect to explosion risk over the current art.
