Proceed as follows to mount the gear unit using anchor bolts:
1. Pull the anchor bolts upwards. To do this you can use a screw or threaded bar that you
screw into the thread on the end face.
2. Attach the washer.
3. Screw on the hexagon nut by hand a few turns.
4. Align the gear unit with the supports (Page 60).
– Observe the values on the alignment strips.
– Maintain the alignment tolerances to the units connected at the input and output
according to the permissible angular and axial displacements of the couplings.
5. Document the alignment dimensions in the form of a report, and archive this together with
these instructions.
6. Keep the anchor bolts in their position by tightening the nuts by hand.
7. Locate the protective sleeve.
8. Attach the hydraulic clamping device.
9. Tighten the screws alternating, taking into account the preload forces (Page 73).
10.Tighten the hexagon nuts to their end stops using a suitable tool.
11.Document the tensioning pressures and preload forces, and archive this report together
with these operating instructions.
CAUTION
Incorrect use of the preload tool
Incorrectly using the preload tool can result in injury.
To ensure correct handling and adjustment of the preload tool, you must carefully comply
with the instructions provided in the manufacturers operating instructions for the preload tool.
NOTICE
Inadequate concrete hardness and strength
Damage caused by inadequate stability of the gear unit as a result of inadequate concrete
hardness and strength is possible.
The fine-grout concrete must be allowed to harden for at least 28 days before tensioning the
anchor bolts.
