The assembly process with the turner
The MSA assembly process comes in two phases:
Turning of the bearing housings
The bearing housings are supported on the upender’s structure horizontally, then vertically and finally the bearings are installed.
It is removed from the tilter by a crane and re-installed horizontally and upside-down on the upender, at 180 °.
It is required to repeat the process to install the bearings on that side.
The hollow shaft is installed horizontally and is lifted with the help of the upender at 90º.
Finally, the bearing housing is inserted into the hollow shaft and assembled.
At the end of these operations, it is necessary to return to the horizontal position to completely assemble the drive train.
