9.2 Preparing finished floor for revolving door assembly
9.2.1 Preparing finished floor.
NOTICE
The operation and structural integrity of Crane
revolving doors depend on their being mounted
on a level floor.
Do not proceed if floor is not flat and level.
• Floor surface should be smooth without
cracks or crevasses.
NOTICE
All Crane warranties are void if door is installed
on a floor that is out of level, or if proper
clearances are not maintained.
WARNING
Risk of injury due to improper leveling!
If finished floor is not leveled before assembly,
faults can occur during subsequent operation of
the revolving door. This can lead to dangers that
can cause serious injury and significant material
damage.
CAUTION
Material damage due to improper leveling!
Laser leveling device with stand:
Improper positioning of the stand or leveling
staff may lead to measurement errors when
leveling. Measurement errors can lead to
incorrect assembly of the revolving door. This
will result in material damage.
• Before leveling, ensure that the stand is
securely positioned on the floor and cannot
wobble or tilt.
• Before leveling, ensure that the laser leveling
device is aligned horizontally on its stand.
• Always position the leveling staff vertically
during leveling.
• After leveling, note the tolerance of ± 2 mm
(1/16") for the individual measured value to
the reference value.
