1.625" x 15'2" BERTSCH #24 PINCH TYPE PLATE BENDING ROLL (3 ROLLS)

(15'2" on tread, 15'4" between frame with (3) x 25" diameter forged steel rolls, capacity in mild steel)

MANUFACTURER: BERTSCH (MADE IN USA)

MODEL: #24

S/N: M-8405 YEAR: 1954

DIAMETER OF ALL ROLLS: 25"

MAIN DRIVE MOTOR: 100 HP

VOLTAGE: 550V

Machine built and equipped with Bertsch Automatic drop hinge to remove formed shells, hand adjustment to the lower

front pinch roll, cut semi-steel main drive spur gears, except the feed pinions which are cast steel, shrouded and mounted

taggering in tandem to insure smooth uniform motion of the forging, heavy pressure poured type journal bearings,

structural sttel base, arranged for power adjustment to the rear roll, taking power from the main drive motor thru a

multiple disc friction clutch, the shells formed to be uniform diameter over their entire length with uniform opening at

the longitudinal butt joint, and to be as nearly true round as can be rolled, without motor; approximate weight 182,000 lbs.

APPROX. WEIGHT(FROM BERTSCH): 182,000 LBS

OVERALL DIMENSIONS:

-LENGTH: 360"

-WIDTH: 159" OR 120" IF WE REMOVE THE BIG GEAR.

-HEIGHT: 134" OR 116" IF WE REMOVE THE BIG GEAR.

The pressure required to form a plate varies with the ultimate tensile strength of the material being rolled. In addition,

a heavier load is required to form the same plate to medium or large diameter.

In view of the above, we submit capacity charts for this machine for mild steel and steel having high tensile, giving full

length boiler and pipe duty ratings for both materials, and giving short thick boiler duty ratings only for both materials.

CHART CAPACITY:
