Framework for belt conveyor

摘要

A framework for a belt conveyor comprising a base structure having a three point mounting arrangement in which the mountings are in a substantial triangular displacement with one upper mounting and two lower mountings. A boom structure has its inward end pivotally connected to the base structure through the three mountings and has an elongate boom member and an elongate support member. The boom member is pivoted to the upper mounting with the support member being pivoted to one of the lower mountings. The support member underlies the boom member and towards its mounted inward end is cranked outwardly and has outer end pivotally connected to the boom structure. A mounting plate is provided near to the crank between which and the second of the lower mountings, a ram and cylinder arrangement is connected. The mountings are displayed angularly to enable the boom structure to be capable of articulation between an outbound upwardly inclined horizontal orientation and an inward substantially vertical orientation.
