5.3.3 The Guide Rollers
5.3.3.1 Replacing the Guide Rollers
Support the hoist cage safely from underneath and
secure to both of the mast pipes using for example
big clamps or other wedges so that the cage cannot
move after the guide rollers have been removed. Loos-
en the tightening of the guide rollers and turn the ec-
centric so that there is a sufficient clearance between
the mast and the guide rollers. Remove the guide roll-
er. Install a new guide roller. However, do not tighten
the axle fastening screw fully as yet. Now turn the ec-
centric with a spanner so that the guide roller lies light-
ly against the mast pipe. Remove the clamps or wedg-
es securing the cage and tighten the guide roller ax-
le’s fastening screw properly.
The lower guide rollers are re-
placed in the same way as
the upper ones. Secure that
the cage stays in place and
remove the cage load for ex-
ample with clamps. Remove
the old guide rollers and install
the new ones. Adjust the guide
rollers lightly against the mast
with the eccentric placed on
the guide roller axle so that the
clamps used for supporting the
cage can be removed.
The replacement of the guide
rollers of both the hoist cage and the lifting mechanism
is carried out according to the same principle.
In case service work is done underneath
the hoist cage, fix the safety clamps on
top of the drive unit and switch off the dis-
connecting switch before going under the
cage.
