building from the top point, but
Place a rope down the length of the
building
Attach the end hook on the first wire
rope to the rope
Pull on the rope, to bring the hook on the
wire rope to the height of the fixing point,
while the second operator unwinds the
wire rope on the storage reeler.
Attach the hook on the wire rope to the

Repeat this operation for the second
wire rope
• Disengage the mechanism of the tirfor
section "Releasing and closing the jaws").
• Place the suspension rope in the blocstop™
detection sling so that it is in contact with the
detection roller inside the yoke of the sling.
• Insert the wire rope into the hole on the
device at the end opposite the anchoring
device (hook or pin).
• Push the wire rope through the device, if
necessary helping it through by operating the
forward lever.
• When the wire rope emerges from the hole on
the anchoring device side, pull it through by
hand up to the required point.
