Evenly tighten the hexagon nuts. Ensure that the gear unit is not deformed or distorted when
tightening the fastening bolts.
Mounting gear units using foundation blocks
The following diagram shows a foundation block:
① Fastening bolt ⑥ Foundation
② Washer ⑦ Foundation block
③ Gear unit foot ⑧ Flat steel plate
④ Height of the completed foundation ⑨ Set screw
⑤ Height of the prepared foundation
Figure 5-3 Foundation block
Proceed as follows to mount the gear unit using foundation blocks:
1. Attach the foundation blocks with washers and fastening bolts in the foundation mounting
points in the gear unit housing.
2. Tighten the fastening bolts until the housing feet are lying flat on the foundation blocks.
3. Using a suitable crane or lifting gear, place the gear unit down on the concrete foundation.
4. Align the gear unit so that the input and output shafts are horizontal using the set screws (if
available) (Page 56).
5. For higher external forces, if necessary, use lateral stops to prevent the gear unit shifting.
6. Before casting the foundation, close the openings in the foundation blocks using a suitable
material (e.g. using polystyrene).
