Figure 3: OPERATIONAL CHECK
• Check that the sides of the housing cannot be slid apart and the
closing button is fully released (the device is closed correctly).
• Check whether the rope is inserted correctly (according to the
sketch on the housing).
• Before each use, carry out an operational check of the device by
test-loading it with your body weight while secured by other
means.
• It is essential to assess the reliability and security of the entire
safety system you are relying on: adequate resistance of the
anchors (EN 795) and the structure they are fixed on, their
correct (higher) positioning to arrest a fall and prevent
pendulum effects, correct positioning of the ropes – e.g.
protecting sharp edges or points of rubbing, preventing ill
running of the descender, redundancy, etc. – to tie a stopper knot
at the free end of the rope. Any overload or dynamic loading of
the descender may damage the rope.
Figure 4: DESCENT AND SHORT ASCENTS
While loading the system, the user should hold with one hand the
free end of the rope and with the other hand gradually pull the
handle (fig. 4/A). This unblocks the rope and allows for a controlled
descent. The maximum permitted speed of descent is 2 m/s. By
pulling the handle down to its terminal position, the user will
activate the descender's second braking position (anti panic) and
the descent will be stopped instantly. To resume descending, just
return the handle in the closed position (fig. 2), and restart the
process. Use a second braking carabiner to lower from a fixed
position (fig. 4/B). Owing to the construction of the device there is
no need to additionally secure the device for prevention of
accidental uncontrolled descents. For short ascents install a rope
clamp in the working end of the rope above the descender device.
While lifting yourself on the rope clamp, pull the free end of the
rope exiting Lory. Never allow any slack between the rope clamp
and the descender device (fig. 4/C).
Figure 5: ACCOMPANIED DESCENT
This method of evacuation may only be adopted by rescuers
specifically trained in this technique. No impact loading is
tolerated. The rescuer fastens the descender to his harness and
connects the injured person by means of an additional lanyard.
There is no need of a redirectional carabiner for the free end of the
rope. For all rescue manoeuvres the use of gloves, however, is
warmly recommended. The rescuer and the injured person must
be secured with an additional independently anchored safety line.
WARNING: With speeds above 1 m/s during rescue operations,
the descender may get hot enough to damage the line.
Figure 6: RIGGING FOR RESCUE
Double rope length should be employed.
Figure 7: HAULING AND PROGRESS CAPTURE SYSTEMS
Hauling from a fixed position with Lory is easiest done either with a
1:1 counterweight or for heavier loads by means of a 3:1
mechanical advantage pulley system (fig.7). Ergonomically easier
pulling from above may be attained by employing another
redirectional pulley on the free end of the rope.
Transition from ascent do descent is done by removing the pulley
system, clipping the rope in a redirectional carabiner above the
Lory and starting to lower (fig. 4/B).
Figure 8: POSITIONING
Use of the work positioning lanyard is mandatory (Lanyard WP).
Fasten the device on the side ring of the harness, pass the lanyard
around a structure and fasten its end with a connector (EN 362) to
the second side ring on the harness (fig. 8A). Protect any contacts
of the lanyard with the underlying structure with the sliding
protector. Always keep the line taught and the anchor point above
the waist level. To shorten the lanyard, pull the free end of the rope
in the direction of the arrow (fig. 8B). To lengthen the lanyard, push
the braking cam in the direction of the arrow with your thumb (fig.
8C).
