6. Instructions for the visual inspection of the descender and rescue lifting
devices
During the visual inspection of the descender device, ensure that the housings and
housing covers have a quality seal which is intact. If it is not, it might mean that the
device has been opened by unauthorised persons.
If the seal is missing or damaged, the use of the device must be stopped immediately
and the device must be handed over to the manufacturer or one of the experts
specified by the manufacturer
6.1. Testing the device housing
Checking the starting point / end point of the rope:
The wear / abrasion of the starting and end point of the rope must be checked. The
abrasion at the start and end point of the rope should not be more than 2 mm; if it is,
the use of the device must be stopped.
The material in the wear area has a polished scrubbed, smooth and shining surface.
The abrasion / wear creates a strong valley in the material.
Checking the device housing:
The housing must be tested for corrosion, mechanical damage, deformation and
crack formation.
A visual inspection must be conducted. If there are cracks, deformations, corrosions
or mechanical damage, the use of the device must be stopped and it must be sent to
the manufacturer for testing.
The bolts must be checked for completeness and fixed seat.
The availability of all bolts must be visually checked. Unfastened bolts must be
tightened using an appropriate spanner. If the bolts are no longer completely present,
the use of the device must be stopped.
6.2. Checking the cam cleat
The cam cleat must be checked for crack formation, fixed seat and operability.
6.3. Checking the karabiner and the round steel shackle
The karabiners and the round steel shackles must be visually checked for corrosion,
mechanical damage, deformation and crack formation. The use of the equipment
must be stopped in case of damage.
