The stand 6 with the indicator is installed so that the indicator leg rests against the upper part of the side surface of the flange, and the indicator arrow is on the division equal to the amount of deformation of the beam, measured with a feeler gauge when straightening the beam.
Installed under the beam (in the deformation zone) limit stops 5, straighten it with a hydraulic press sequentially in the horizontal and vertical planes, monitoring the results of straightening with a feeler gauge on the square 4 or on the indicator. The maximum force of the press at the place of application of the load should not exceed 10,000 kgf, so that excessive deformation of the casing section does not occur.
If the stop height is correctly selected experimentally, the beam 5 can be adjusted without using a square or indicator, followed by checking it for deformation.
The beam is removed from the press and checked as indicated above, replacing flanges 3 (A.70172) with test ones.
In the absence of appropriate equipment, as an exception, straightening of the beam is allowed sequentially from each side, but with mandatory checking of the deformation of the beam on both sides.
