n one sense they are a traditional product: an overhead gantry feeds fuel, or logs, or scrap metal or cement or indeed any raw material from a delivery
mounted grab, moves on an A-frame or on rails to feed raw material to the ever- demanding maws of the machinery that will transform it into something useful. Whether it is feeding biomass into a
power furnace or steel into a mill, process cranes are there to do the same task, over and over, many times a day or an hour. It makes sense, therefore, to optimise their design to the particular task in hand.
It makes more than sense, indeed a necessity, that the process crane is reliable. Frequently they are required to operate 24/7, for 52 weeks a year. Downtime in this component, for repair or for maintenance, can bring the entire factory to a halt. One other thing they have in common:
their centrality to do the task in hand. The rate at which the factory operates depends on the rate at which they feed in raw
