Abstract
A low profile, wide belt mobilized bridge carrier is used in low vein mining operations. The mobilized bridge carrier of the present invention includes a carrier frame that carries the propulsion system and that supports the receiving boom, the discharge boom, the cab assembly and the canopy. The preferred mobilized bridge carrier is track propelled, and includes at least a pair of crawler track assemblies which are actuated by an electrically operated hydraulic motor. The receiving boom and the discharge boom are pinned together and each are pivotally mounted on carrier frame at a main pivot point. The carrier frame is of reinforced construction. The receiving boom and discharge boom of the present invention include low profile side panel assemblies which allow the present mobilized bridge carrier to be used in "low vein" mining applications. In order to compensate for any inherent loss of strength in the receiving boom that results from lowering the profile to accomplish its purpose of operating within low veins, the present receiving and discharge booms incorporate certain novel reinforcements, including inside reinforcement plates that extend substantially throughout the length…
