The final checking of the balance
Before the balancing is complete all clamps
and sliders of the bottom roller guides are
removed, then the final checking is done.
•
Remove the clamps of the top roller guides
•
Drive the car down
•
Remove the clamps and sliders of the bottom
roller guides
•
Drive the car back to the mid-point of the
shaft
•
Check the balance from the gap “A” of the top
roller guides movement limiters (see chapter
4). If it is necessary, adjust the position of bal-
ance weights.
•
Before new checking, sway the car powerful
back and forth in lateral and depth direction
to overcome the friction between the rollers
and the guide rail.
•
Drive the car down and shift the weights to
exactly the same place at the fixing profile.
•
Fasten the weights to the fixing profile
The adjusting of balance must be done so
that own weight is not affecting the bal-
ance. You can check the balance by stand-
ing at the hitch point, from another car (in
case of multiple cars in one shaft) etc.
Remember to use a safety rope when
required.
