ABSTRACT:
The invention comprises a ceiling mounting bracket for securement to a mine tunnel ceiling and which is used for suspending a monorail therefrom; a mobile advancing conveyor system is, in turn, suspended from the monorail and used to facilitate removal of ore from the mine tunnel. The ceiling mounting bracket includes a flat mounting plate disposed contiguous to the mine ceiling, a longitudinal slot formed on the mounting plate and which is parallel to the monorail when the monorail is pendent from the ceiling mounting bracket, and a pair of opposed lateral slots perpendicular to the longitudinal slot for permitting lateral adjustment and positioning of the ceiling mounting bracket prior to securement to the mine ceiling. A ceiling bracket bar is disposed subjacent to the ceiling mounting plate and is capable of slidable, longitudinal, reciprocable movement parallel to the slot. Attached to and suspended from the ceiling bracket bar is a rail hanger which moves in conjunction with the bar and to which one end of an individual segment of the monorail is mounted. In order to compensate for mine tunnel ceiling undulation, a plurality of rail hanger extensions, each a different length, can be interposed between, and attached to, the ceiling bracket bar and the rail hanger.
