Gearless Lift Machine
WSG-18 and WLG-18
Operating Instructions
Be sure to check the base frame or founda-
tion loads by calculation before installing
the lift machine.
The lift machine may only be installed if the relevant
safety precautions have been met. The machines can be
used in lift systems with a machine room.
The machines may only be installed, electrically connect-
ed and put into operation by trained specialist personnel.
The system-specific conditions and the requirements of
the system manufacturer or plant constructor must be
met.
Cover the machine and especially the
brakes when doing any machining or dust-
producing work in the shaft or machine
room.
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.
Degree of protection
The lift motors are designed with degree of protection
IP 23 M / IP 12 5, i.e.
M : during operation
S: at rest.
The traction sheaves are provided with holes for the
cooling air circuit and with external fins for stiffening.
Therefore, take special care.
When making the electrical installation, make sure the
cable connections to the terminal boxes are sealed tight-
ly.
Ambient conditions
The following ambient conditions must be ensured on
site:
Altitude:
max. 1,000 m a.s.l.
Ambient temperature:
- 5 ... 40°C
Max. rel. humidity:
85 % at 20°C (no moisture con-
densation)
Install the machine so that ventilation is not obstructed,
i.e. sufficient heat dissipation by convection and radia-
tion must be ensured.
The torque and power values indicated in the Technical
Data apply to the above ambient temperatures and alti-
tudes. In case of a deviating altitude and/or ambient
temperature, the reduction factors k shown in the dia-
gram below must be used.

Fastening the machine
The rope force can be applied to the lift
machine in any direction.
The machine or base frame should be
mounted on rubber pads for vibration
damping.
The machine is fastened using 8 M 20 bolts (strength
class 8.8; tightening torque: 395 Nm).
The permissible uneveness 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.
After completing the adjusting work, tight-
en the 8 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 dis-
tance between the rope and the rope slip-
off guard does not exceed 1.5 mm.
If the machine is not installed in the
machine room "on top" of the shaft, the
installation of the rope slip-off guards may
have to be modified. In this case, optional
rope slip-off guards are available that can
be fitted to the foot area of the machine.
