DESCRIPTION
A. Rotary Car Dumper Building: The rotary dumper building was
designed by the Heyl and Patterson Company and built by the
American Bridge Company. It is located south of blast furnace
number six near the shoreline of the Monongahela River. Laid out
on a north-south axis, it is 40'-6" wide x 72'-l" long x 17'-8
5/8" high. The steel framed structure of the building is covered
by corrugated metal. The building's gable roof is supported by
Fink trusswork. An approximately 27'-0" wide opening in the
floor runs the length of the building in order to accommodate the
rotary car dumper. Located at the northwest corner of the
building is a 10'-0" square x 9'-0" high operator's room. At the
northeast corner of the building is an approximately 9 f -0 M wide x
10*-0" long x 9 , -0" high motor control room.
Construction Date: 1957.
B. Rotary Car Dumper: The 26'-0" diameter x 60'-0" long steel
framed rotary car dumper, designed and built by the Heyl and
Patterson Company of Pittsburgh, PA, is laid out on a north-south
axis. The centerline of the car dumper is located 22'-2" off the
east wall of the building. Its southern end coincides with the
south wall of the building. Each end of the car dumper is made
up of a braced steel column-like shape formed into a 26'-0"
diameter ring sitting above and below the floor line of the
building. The outside flange of each ring supports one of the
car dumper's two drive chains and a steel rail around its
circumference. Each rail rests on two sets of 12" diameter sill
wheels. The sill wheel sets are composed of two steel rail
wheels which are secured by clevis connections to a large steel
column, laid out on a east-west axis, located directly below each
ring. The columns, which are supported by concrete footers
located in the basement of the building, support the sill wheels
near its eastern and western ends.
The inside flange of each ring forms the parameters of an
