Leight-Mardon Port Botany N.S.W.

This installation features a single overhead vacuum crane lifting reels of paper, of varying heights, from a short conveyor and stacking them around the store floor to the prescribed height. The outfeed conveyor system is also short and uncomplicated.

The “Movement Controller” replaced the original DEC-PDP 11 computer for less than it would have cost to replace the hard disc drive of this computer.

The stacks were composed of like reels within a given range of ages, arranged in around the outfeed according to their movement class.

Communications between the “Movement Controller” and the cranes is via high-voltage bus bars.

There is no host computer system.

All PLCs are Allen-Bradley.
