4.1
Areas of application
The devices must be as far as possible installed in a covered room.
If they are used in the open, protect the units against the effects of weather such as rain, hail, snow, direct
sunshine, dust, etc. - we recommend to use a cover in parking position. If the device is set up in a
continuously humid environment with strong temperature fluctuations, the correct functionings are
endangered by the forming of condensation.
Ambient temperature: - 20°C up to + 40°C. Humidity: 100 % or less but not under water

4.2 Design
HADEF pneumatic wire rope winches for
stationary use are fitted with holes for installation.
The housing is made of steel plate. The two
housing halves are connected with a torsion-
resistant traverse. Transport eyes are situated at
the upper edges of the housing. The drum is
situated parallell to the drive.
