HAER NO, PA-115<br />
(Page 117)<br />
two. It is powered by a 20 hp, 1750 rpm Sterling A.C. motor<br />
connected to a Falk gear drive which is attached to a 18"<br />
diameter winch drum wrapped with a 7/8" diameter steel cable.<br />
The motor, drive, and winch drum assembly is located on a 10 f -5<br />
3/4" wide x 11*-8" long steel column supported platform 11'-6"<br />
below the coke track system and 103'-6" north of the centerline<br />
of blast furnace number two. The cable extends from the winch<br />
drum in a northerly direction for a distance of SS'-G" where it<br />
wraps around a 2'-6" diameter steel column supported sheave wheel<br />
before rising vertically at a slight incline for a distance of<br />
7 , -2 1/2" where it rides over, under, and between two 2 , -6"<br />
diameter steel column supported sheave wheels upwards onto the<br />
coke trestle platform. Attached to the end of the cable is a<br />
large "C" hook which latches onto the hopper cars. The capacity<br />
of the car puller is 40 feet per minute.<br />
Construction Date: 1964.<br />
2. Car Puller Number Two: Car puller number two serves the<br />
stockhouse bins associated with blast furnaces number three and<br />
four. Its motor, drive, winch drum, and pulley assembly operated<br />
in the same manner as car puller number one with the exception<br />
that the Sterling A.C. motor is smaller (10 hp @ 1800 rpm) and<br />
the gear drive is manufactured by the Stephen-Adamson<br />
Manufacturing Company.<br />
Construction Date: 1960.<br />
3. Car Puller Number Three: Car puller number three,<br />
designed by the Stephens-Adamson Manufacturing Company, is a<br />
10,000 pound continuous reversible wire rope and car puller<br />
machine. It served the stockhouse coke bins associated with blast<br />
furnace number six. The system is powered by a small motor<br />
running at 1760 rpm connected to a Stephens-Adamson gear drive<br />
which is attached to two 18" diameter winch drums straddling the<br />
motor on a east-west axis. The motor, drive, and winch drum<br />
assembly is located on a steel column supported platform<br />
approximately S'-O" below, and in between the east and west coke<br />
tracks, 161 , -4 1/2" north of blast furnace number six. A 7/8"<br />
diameter cable extending from the western winch drum travels<br />
around eight 27" diameter sheave wheels laid out in a 278*-0"<br />
long x 25 , -3" wide rectangle which surrounds the east and west<br />
coke tracks before returning to the winch drum located on the<br />
east side of the motor. Attached to the taut steel cable<br />
rectangle near the southern end of its eastern border and near<br />
the northern end of its western border is a sling assembly<br />
eguipped with a "C" hook which is used to tow the railroad hopper<br />
cars onto the east and west coke tracks. The capacity of the car<br />
puller is 40 feet per minute.<br />
Construction Date: 1962.
