3.1
General
If the elevator car is not balanced, the sliding and
roller guide shoes are subject to excessive load.
This leads to rapid wear of the guide shoes and in
case of roller guide shoes to quaky running, which
can be felt in the car. Therefore all cars must be
balanced independent of speed and travelling
height.
Accurate balancing can be carried out first after
the car is fully installed and suspended by the
ropes.
The removable clamps and sliders are used to ease
the balancing and installation.
3.2
Balancing
Before the balancing is done the roller guides must
be aligned using the door lines as reference line:
•
Drive the car to a suitable working height near
the lowest floor level
•
Adjust the position of the roller guides so that
the gap between the car door and the landing
door is equal at top, bottom, left and right
(refer to chapter 2.1 and 2.2).
check also that the safety gear can still be
adjusted side ways.
Do not try to untwist the car frame with
the roller guides. If untwisting is required,
then loosen the top fixing between car and
the frame, force the frame to right position
and tighten the fixings.
