Installing the overspeed governor
in the machine room
Always pay attention to the overspeed
governor rotational direction during each
stage of installation.
Preparation
The overspeed governor can either be installed
directly on the machine room floor or on a support
structure.
Lifts complying with EN-81 require the
rope aperture to be kept as small as possi-
ble and to be fitted with a 50 mm high col-
lar. A corresponding safety collar must be fastened
to the floor before installation takes place.
If a cement floor is to be poured over the
concrete after installation, bear this in
mind when fitting the collar.
Installation procedure
Always pay attention to the overspeed
governor rotational direction during each
stage of installation.
