Ascenders (mechanical devices used for self-rescue.)
18.3.1.
Condition of the Body and the Anti-Return Stop
Check that the body is free from cracks, deformities. They are the sign of a fall or factor higher than one(1). Beware there are no
trace of wear or corrosion. Pay particular attention to the area where the rope runs, level with the holes. Check also for any
deformities that may be present on the upper part of the body. Check for any deformities that may be present on the upper part of
the body. Check for deformities of the anti-return stop (sign of a fall factor higher than one).
18.3.2.
Condition of the Cam
Check that all the teeth are present and their state of wear. If the teeth are worn, test the operation of the rope clamp/grab on a
muddy rope. Beware there is no trace of carrion. Inspect the condition of the rivet.
18.3.3.
Condition of the Security Catch
Check that the catch is not broken. Check its pin.
18.3.4.
Check on the Rope if Sliding upwards and Jamming when Pulled
Downwards
For this check, use the different diameters of rope as advised (at least the diameters of rope that you use). Check that the rope
clamp/grab slides up the rope easily and that it jams when it is pulled downwards.
18.3.5.
Effectiveness of the Spring of the Cam
Clean with a brush and soapy water and, if necessary, oil with silicone. Oil the pins and the spring. Warning, wipe the friction
components with a rag.
18.3.6.
Effectiveness of the Spring of the Security Catch
Clean with a brush and soapy water, if necessary, oil with silicone. Oil the pins and the spring. Warning, wipe the friction
components with a rag.
18.3.7.
Opening of the Security Catch
Check that the safety catch opens completely on the body of the rope clamp/grab.
18.4.
Hardware Connectors
18.4.1.
Visual Check of the Body, of the Hook or Nose of the Connector, of
the Closing Gate, of the Rivet and of the Sleeve
On the connector, look for any cracks, marks: look for the cause; sharp tools, impacts. This analysis will provide information on
the history of the product. Check that the connector is free from deformation, wear. For a connector, a wear mark more than 1
mm deep is serious. Beware there is no trace of corrosion which may be present on the body. Pay particular attention to the
angles, to the hood and to the gate. Check that the rivet and the sleeve are present and check their condition.
18.4.2.
Check of the Correct Alignment of the gate with the Hook
Operate the gate and check the correct alignment of the gate with the hook.
18.4.3.
Check of the Effectiveness of the Return Spring and of the
Articulation of the Gate
Check that the spring fulfills its function and that the articulation of the gate works correctly. Clean with a brush and soapy water
and if necessary oil with silicone, oil the pins and the spring. Warning, wipe the friction components with a rag.
18.4.4.
Operation of the Locking System
Finally, ensure that the locking system works properly. Clean with a brush and soapy water and if necessary oil with silicone oil.
