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 DEG 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. |
