3.4 Installation on concrete foundation
3.4.1 Scope of delivery
The machine delivery does not normally include installation, shim plates, mounting bolts,
foundation plate set or sole plate set. These are delivered according to special orders.
If new fixing holes need to be drilled, please contact ABB to ensure suitability.
3.4.2 General preparations
Before starting the installation procedure, consider the following aspects:
• Reserve sheet steel material for shimming the machine. Possible alignment adjustments
require shims with thicknesses of 1, 0.5, 0.2, 0.1 and 0.05 mm (40, 20, 8, 4 and 2 mil)
• Reserve a recoil hammer, adjusting screws or hydraulic jacks for axial and horizontal
adjustments
• Reserve dial indicator gauges, or preferably a laser optical analyzer, to achieve accurate
and precise alignment of the machine
• Reserve a simple lever arm for turning the rotor during alignment
• With outdoor installations provide sun and rain protection to eliminate measuring errors
during installation.
NOTE: Machines are delivered with jacking screws for vertical adjustment at each foot.
3.4.3 Foundation preparations
3.4.3.1 Foundation and grouting hole preparations
Foundation studs or sole plates are used when the machine is anchored to a concrete foundation.
Consider the following aspects when preparing the foundation:
• The upper part of the foundation has to be swept or vacuum cleaned
• Walls of the grouting holes must have rough surfaces to give a good grip. For the same
reason they must be washed and rinsed and thus free from pollution and dust. Oil or grease
must be removed by chipping away slices of the concrete surfaces
• Check that the position of the grouting holes and the height of the foundation agree with
corresponding measurements on the drawing provided
• Attach a steel wire on the foundation to indicate the center line of the machine. Mark also
the axial position of the machine.
3.4.3.2 Foundation studs or sole plate preparations
If shims and foundation studs are part of the delivery, they will be delivered as separate items.
The assembly of these will be made at site.
