The hub function has been tested according to EN1496:2006 with loads of 30 kg, 150 kg and 280
kg, each time with a dry and wet rope.
The maximum hub nominal load for Milan devices according to EN 1496:2006 is 120 kg. The
device can, however, support loads of up to 280 kg in emergencies. In this case, manual forces
and rope wear increase and no longer correspond with standard specifications. A safe rescue is
still possible.
8.3 RECOMMENDED MAXIMUM ABSEILING DEVICE
PERFORMANCE
•
Max. abseil distance with one person up to 75kg: 3,000m
•
Max. abseil distance with one person up to 100kg: 2,500m
•
Max. abseil distance with one or two persons up to 150kg: 1,000m
•
Max. abseil distance with one or two persons up to 200kg: 400m
•
Max. abseil distance with two persons up to 260kg: 200m
•
Max. abseil distance with two persons up to 280kg with deflection: 200m
(Since the device is operating in extreme conditions in this case, a higher safety factor must be
observed.)
The stress on the device can be reduced through deflection (see 4.6). If working with a deflected
rope, the maximum lowest value recommended can be applied. In the USA, abseiling with two
people is permitted only with deflection.
8.4 RECOMMENDED MAX. ABSEILING ROPE PERFORMANCE
The lower the abseil 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 or any stressing
caused by edges. It is especially when the lift function is used at the same time that this can lead
to greater wear and tear. The max. rope run should not exceed approx. 50 abseilings. The rope
should also be constantly checked for wear and tear.
8.5 RECOMMENDED MAX. LIFTING PERFORMANCE
Lifting puts a greater strain on the device and the rope than abseiling. This can create slip if the
lift is frequently used. This does not in general mean that there is then a danger because the
person can still be safely abseiled. If this is not the case, the max. lifting performance should be
100m or 10 rope runs. If local conditions allow abseiling, the lift can be used more frequently, but
rope wear must then be checked more often.
