•
Using suitable lifting gear, place the gear unit on the concrete foundation.
•
Align gear unit horizontally by in and output shafts.
─ if using stone bolts, with shims.
─ if using foundation blocks, with the aid of the set screws (if available).
•
If considerable forces apply, it may be necessary to use stops to prevent the unit from displacement.
Before pouring the concrete foundation, fill up the openings in the foundation blocks with
adequate material such as polystyrene.
•
Pour concrete into the recesses of the stone bolts or foundation blocks.
When the concrete has set, tighten the hexagon nuts of the stone bolts or fastening
bolts of the foundation blocks to the specified torque (see item 6.17).
The gear unit must not be excessively stressed when tensioning the hexagon nuts or
fastening bolts.
6.3.2.4 Fitting on a concrete foundation by means of anchor bolts
This type of fastening is only permitted when using a base plate!
•
Clean the undersurface of the gearunit base.
•
Place support on the base plate in the fine grout.
•
Insert anchor bolts.
•
Place pressure plates in position and screw nuts on.
•
Place wood under the anchor bolts so that they are about 10 mm from the upper edge of the support
(see figure 12).

Anchor bolt
•
Place gear unit on foundation.
Use only the 4 eye bolts provided to attach lifting equipment to the unit.
Do not use the front threads at the shaft ends to attach slinging and lifting gear for
transport.
•
Pull anchor bolts up (for this a bolt or threaded rod can be screwed into the thread on the front face).
•
Fit washer.
•
Screw on hexagon nut a few turns by hand.
•
Align gear unit with supports (see figure 13).
─ The values punched into the screeds must always be observed.
─ Alignment tolerances in relation to the units on the input and output sides are to be in accordance
with the permissible angular and axial displacements of the couplings (see coupling drawings).
