<p>A training idler for a belt conveyor comprises a frame carrying the idler rolls, a cross-member and a carrier pin carried by the cross-member on which the frame is itself carried. The axis of the pin is arranged horizontally parallel to the direction of belt travel and vertically at 25° to the direction of belt travel. The pin is journalled in a plastic bush carried by a metal bearing carrier. Adjustable stops are provided to limit the amount that the frame can swing about the axis of the pin.</p> |
