Workers are preparing the molding for the W-line component of the
East Saddle in the foundry shop of Japan Steel Works (JSW). Two days
later tons of hot molten steel was poured into this mold to make the
cast. |

The pouring of hot molten steel into a casting mold at the foundry
shop of JSW. This was to make the W-line component of the East Saddle
of the bridge. |

The “West Jacking Saddle” is
being hoisted from the location where it was cast, moved by crane to
the opposite end of the foundry shop, and torch-cut and hammered to
remove the sand casting mold. |

Seen here is the completion of the casting phase in which the 150
ton “West Jacking Saddle” was made in the foundry shop
of JSW. It was then moved by rail to an adjacent building to undergo
the heat treatment phase. |
