Rack device for advancing a mining machine

摘要

A rack device for advancing a drum cutter mining machine used in underground mining operations. The rack is comprised of a plurality of rack sections positioned end-to-end wherein the discrete sections are held together by brackets which connect two adjacent rack sections. The bracket contains a bracket wall which has a top surface positioned directly beneath the end pins of the discrete rack sections. Force exerted on the rack pins during the translation of the drum cutting mining machine bears upon the bracket wall thereby diminishing damage to the rack structure caused by tilting forces created during translation of the mining machine.
