We commonly use spare cranes while our bridge crane is being serviced. We typically have smaller cranes that can travel via track accross the pit and load our coke crusher. If both cranes are down we have to use a fairly large (500 ton) crane that can extend over the top of the bridge crane rails. We then load dump trucks and transport the coke that way. It tends to get a bit messy though because it is often hard to load the dump trucks neatly without spilling some over the sides.
