In the mechanized foundry, which of the following parts is used for suspending the ladle during pouring of molten metal? Correct Answer Crane

In foundry, the assembly of moulds and cores on a conveyor are carried to the casting station where the liquid metal is poured by the ladle which is suspended by the application of crane, and then moulds filled with liquid metal are cooled as they pass through the cooling tunnel and at last arrive at the knockout station for extraction of castings.
