Setting up
DANGER
f
Be sure to use calculations to check the base frame or foundation loads before installing the lift machine.
f
The lift machines must be installed by trained and qualified personnel with professional knowledge of mechanical
engineering and lift construction.
•
The machines can be used in lift systems with or without a machine room.
•
The permissible unevenness of the mounting surface is 0.1 mm. The mounting surface must be sufficiently dis tortion-
resistant and stable to accommodate the forces occurring in the system.
•
The rope force can be applied to the lift machine in any direction.
•
The machine must be mounted on vibration dampers for vibration damping.
•
No welding work may be performed on the lift machine, nor is it permissible to use the machine as a mass point for
welding work. This might cause irreparable damage to the bearings and magnets.
•
If there are more grooves on the traction sheave than the number of ropes used, position the ropes either in the centre
of the traction sheave or towards the motor end.

The measuring system is only accessible from the rear side. Therefore, leave enough space between the wall and the
rear side of the machine or ensure that the machine can be moved away from the wall.
WARNING
f
Cover the machine and especially the brakes when doing any machining or dust-producing work in the shaft or
machine room.
Securing the machine
•
Fasten the machine using four
M 20 bolts - strength class 8.8 tightening torque: 395 Nm
.
•
After completing the adjusting work or after a breakdown, tighten all the fastening bolts of the machine, using the
specified torque .
•
Lift machines are generally equipped with rope slip-off guards. After putting the ropes in place, adjust them so that the
distance between the rope and the rope slip-off guard does not exceed 2 to 3 mm.
•
If the lift machine is not installed at the head of the machine room as is usually the case, it may be necessary to
modify the fitting of the rope slip-off guard to fulfill the requirements of EN 81-20 . Optional rope slip-off guards are
available for this purpose.
