Original Operating Instructions UNIDRIVE
A UNIDRIVE Descender Device
Descender devices are used for the rescue of people whose means of exit via stairs, ladders or lifts is
blocked due to fire, gas, power failures or other, unforeseeable events.
The UNIDRIVE devices are equipped with centrifugal force brakes which ensure a constant descent
velocity for the person being rescued. The devices are so constructed that the brake unit works com-
pletely independently of the rope unit. Thereby smooth functioning is guaranteed even in bad weather
conditions as no moisture from the ropes affects the brake unit.
Thanks to the automatic functioning of the UNIDRIVE descender device, no additional person is
needed for the descent activity.
The technical basis of the descender device is the European Standard, EN 341, which has been de-
st
veloped on the basis of the "European Council Directive 89/686/EEC of the 21 of December 1989 for
the harmonization of the legal regulations of the Member States relating to personal protective equip-
ment".
1. General
The manufacturer accepts no liability whatsoever arising from incorrect and / or improper operation or
the unsafe operating condition of the UNIDRIVE during commissioning. Therefore it is very important
that these operating instructions are read and understood. Please do not hesitate to contact the manu-
facturer in the event of queries.
The operating company (owner) of the equipment is obliged to make these operating instructions
available to all operators of the UNIDRIVE and also to ensure that they are read and understood be-
fore commissioning. The Chapters Commissioning, Operating and Warning Information especially are
of great importance for the safe and effective use of the working device.
Over and above this, the manufacturer recommends practical training by authorized instructors who
explain operational safety in actual practice.
1.1 Correct and Proper Use
UNIDRIVE can be used as a descender device.
Used as a descender device, one or two persons simultaneously or several people individually, one
after the other in shuttle operation, can lower themselves vertically from a high location to a lower one
at an automatically restricted descent speed.
