4.2.3 Mounting the blocfor™ 20R/30R 150 kg onto
a structure / an anchor point.
• The anchor point for the blocfor™ 20R/30R 150 kg
must always be higher than or at the same level as the
operator’s feet, and never underneath.
• Use an EN 362 connector to connect the blocfor™
20R/30R self-retracting fall arrester to the anchor
point or to a structure whose load bearing capacity
must not be less than 12 kN.
5. Operating principle
Performing a rescue operation with a blocfor™ R
DANGER
A second person must be available nearby to
perform a rescue operation if required.
The rescue operations required must be studied and
assessed in advance to define the human resources
and equipment necessary to rescue a suspended
person in less than 15 minutes. Failure to meet this time
limit places the fallen person in danger.
5.1.
Engaging the recovery (rescue)
function
• (1) Press on the red locking button to engage the
recovery function.
• (2) Pull out then rotate the winder to rescue the operator:
– rotate the winder clockwise to raise the operator,
–
rotate the winder anti-clockwise to lower the
operator.
5.2.
Returning to fall-arresting mode
5.2.1 Winding up the cable into the device
Once the rescue has been completed, wind up the
cable fully into the device by rotating the winder
clockwise.
DANGER
Do not disengage the device’s recovery function
until the cable has been fully wound up into its
housing, since otherwise the cable may retract by
itself at a dangerously high speed.
5.2.2 Disengaging recovery mode
•
To disengage the winch mechanism, press
simultaneously on the red button (1) and on the
spindle of the winder (2).
• Ensure that the winder is oriented vertically, with its
handle at the top, when performing this operation.
• Pull out the handle (3) before folding it down (4).
