The illustration shows the correct alignment procedure between two roller bed sections (two idler units
in the picture above).
Conventional roller bed alignment:
1. Ensure that the floor is leveled and free from cracks or other damages.
2. Ensure that heights are within limits.
3. Ensure that both sections have their wheel stands mounted at the corresponding place, i.e., C1 and
C2 are equal.
4. Ensure that sections are not tilted.
5. Ensure that: A1=A2±0.5mm (0.02in.) and B1=B2±0.5 mm (0.02in.).
5.7 Welding
WARNING!
The vessel must be earthed independently from the roller beds when welding.
Earthing through the roller bed causes serious damage to the roller beds.
The earthing requirements of specific welding procedures must be known, and earthing should be
correctly connected to the vessel before welding. Standard roller beds are not designed to earth the
vessel during welding.
5.8 Stopping the roller beds
On the wireless remote - control pendant, press the toggling pushbutton for a continuous rotation to
stop the rotation.
Rotation starts again when the pushbutton for continuously rotation is pressed.
NOTE!
Use the emergency stop button on the control panel and wireless remote - control pendant in
case of an emergency only.
