Why APPI:  Using a winch to extend conveyor belts is a common practice in a wide range of fields.  However, in applications like potash mining, space is at an absolute premium and conventional approaches to installing a winch for this purpose simply don’t work.

In this case, the only place it was possible to mount the winch for extending new conveyor sections was at 90 degrees to the belt and outside the conveyor frame.  The resulting right angle bend to spool the wire rope with virtually zero fleet angle was overcome by the use of one of our proprietary AutoAdvance Line Spoolers (AALS).  With the winch and AALS assembly mounted to the side of the frame, the wire rope leads to a change of direction sheave mounted in the center of the conveyor track and then to the section being extended.

With the ability to properly spool over 200 feet of wire rope – without any kind of external assist – the mining crew can focus their attention on the proper extension of the conveyor frame.  Kasmet Niyongabo, the mechanical engineer at the mine where the system was installed, said the winch with AALS has worked flawlessly since installation.  With this application solution in hand, he is looking to apply it to other machines that have the same problems with winch location and wire rope spooling.
