Tip from our experts

Careful machine alignment with simple tools

 

It is paramount that ample care is taken during transportation of motors in order to ensure safe delivery. During the alignment of the machines great care should also be taken to prevent damage of bearings prior to commissioning.


DO NOT attempt to use hammer blows to move the machines. Every blow on the motor causes pitting on the inner and outer bearing surfaces.

When shimming, PRUFTECHNIK recommends that the machines be moved vertically using sturdy high quality lifting devices as shown in the below images. Abrupt lowering of machines using small, unhandy levers could exact real damage to the machines.

Jack bolts on the feet of the machines are recommended for horizontally moving machines. In the absence of such bolts, hydraulic devices or sash clamps can be used.
