It is also possible to change breaking force by changing exit
angles form rope guides placed on tube.
Due to different variables it is difficult to
give sharp datas on breaking forces. As an
example the following datas was mesured
with a Yale Double Esterlon 12 mm (1/2”)
brand new rope:
¾ wrap: kg 80
2 ¾ wraps: kg 400
3 ¾ wraps: kg 800 (See Fig. 10)
Attention:
When lowering the operator
must always keep clear from
lowering zone. Always wear
PPE.
User must always control rope with both hands. Rope must always be coiled and stored in a
bag to avoid knots and tangles. Never stay in the direction of the rope. Never twist the rope
around hands, arms or any part of the body.
Attention!
During rigging operations dynamic loads can accour. It is imperative to reduce dynamic
loads. To many wraps or sudden stops during lowering can chock load the entire system
(lowering device, rope, block, sling, rigging point) and lead to potential dangers. For exam-
ple 100 kg x 1 mt free fall genrates 600 kg impact force! Never stop the work suddenly.
Always let the load run and break it slowly to reduce kinetic force.
