RECOMMENDED MAX. ABSEILING ROPE PERFORMANCE
The lower the abseiling height, the more often the rope runs through the device. Low abseiling
heights therefore result in greater wear and tear to the rope. In addition, rope wear also
depends on various other factors, such as how carefully or not the user handles the rope.
Edges can cause serious stress to the rope especially if the lift function is used at the same
time that this can lead to greater wear and tear. The rope should also be constantly checked
for wear and tear.

When abseiling several people, the rope counterweight must be taken into consideration. Once
the incoming rope is hanging freely, low weights can only be lowered to a certain abseiling height.
7.6 REDUNDANT UNITS (STANDBY UNITS)
Training is not an emergency situation!
In general, a second independent safeguard (redundancy) is always to be used. The possibility
of unforeseeable events, technical failure and human error can never be totally excluded! A second
MILAN and MILAN 2.0 device, for instance, can be used as redundancy/standby.
7.7 OVERLOAD
Devices which have been subjected to the force of arresting a fall or a overload have
to be removed from field. Unit is then sent to an approved service agent for inspection or repair.
7.8 TEMPERATURE
The Milan device can be used in temperatures between – 35° C up to + 65° C. The Rescue
Device Driver can be used between 0° C and +40° C (acc. to manufacturers specification).
