Equipment Beam Stage Loader and Crusher. When the coal has been hauled to the maingate, it then has to be transferred through a 90 o turn, and loaded onto the maingate conveyor. This function is carried out by the Beam Stage Loader or BSL , which is another scraper conveyor, in this case with steel plates on both sides and runs from the maingate drive to the maingate conveyor (belt).
