ABSTRACT:
An expandable flexible conveyor with a conveyor wheel axle and yoke support. The support includes an upper sleeve adapted to receive an axle. The support includes a lower sleeve adapted to receive a span member. A support body connects between the upper sleeve and lower sleeve. The support body includes a bend adapted to receive a portion of a downward load placed upon the plurality of rollers and axle. The upper sleeve and axle are adapted to distribute a downward load placed on the plurality of rollers across the width of the support. The bend receives the downward load and stiffens the support body to support the downward load. The lower sleeve and span member maintain the support body in a substantially vertical orientation while the downward load is on the plurality of rollers, and supported by the support body.
