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.

(

1

) If a supporting base is being used, it must be

screwed to the overspeed governor.

(

2

) Position  the  overspeed  governor  (with  or

without  base)  and  align  the  plumb  line  over
the centre of the safety gear

(

3

) Mark the drill holes and put the stud anchor in

place  (stud  anchors  are  delivered  with  sup-
porting base)

(

4

) Fasten down the overspeed governor (with or

without supporting base)

Take care of tightening torque
