Platform
The scaffold round the cupola, built for convenience in charging. If possible, they should always be of sufficient area to accommodate the stowing of all the iron, fuel, material for repairs, etc., required for one day's melting at least, for which reason there should be no mistake made as to the strength of such structures. If there be a system of tracks in the yard, an incline from the platform will serve to communicate therewith. See PIGIRON SCALES; CHARGING-PLATFORM.
Platform-cranes are walking cranes erected on trucks which run on rails or road. See CRANES.
