7.
Attach the top plate by bolting. Do not fully tighten as shimming may be
necessary to level
The threads in the top plate of the 5-250kg modules are 1/2”-20 N.F.
threads. The threads in the top plate of the 500-5000kg modules are 3/4”-
10 N.C. threads.
8.
Repeat steps 4, 5, and 6 for the remaining mounts. The vessel should now be sup-
ported on the mounts alone.
9.
If necessary, move the vessel to its final position. Verify that there is no initial
misalignment between the base plate and top plate. Verify that the load button is
centered in the top plate to allow equal travel on either side.
10. If the jacking nuts were used to isolate the load cell from the load, lower them to
the jacking spacers to lower the vessel to rest on the load cells.
11. Attach the base plates to the foundation using anchors for concrete or by bolting
or welding to a steel structure. Verify that the base plates are no more than ±.5°
out of level. Shim as necessary.
12. Check that the top plates are no more than ±.5° out of level. Shim if necessary
and fully tighten the bolts.
13. The load distribution can be checked by lifting the vessel sightly at each support
point in turn or, more accurately, by exciting each load cell in turn and measuring
the output with a voltmeter. The variation in load among the cells should be no
more than 20%. Shim if necessary.
14. Check that the two screws securing the load cell to the base plate are tight.
