4.3 ABS-12 descending brake
Descending systems, e.g. on drilling derricks, must have an additional descending brake in order to
comply with the German Mining Authority regulations. It serves as an auxiliary brake when there is
doubt about the permanent usability of the descender device due to severe climatic conditions (rain,
frost, sea conditions, etc.).
The descending brake has a U-shaped body similar to a vice with a rope guiding shoe on one side
and a brake shoe on the other side.
The device is placed around the suspension rope after the brake shoe has been sufficiently opened
by turning the screw spindle. The brake shoe is then moved in the opposite (closing) direction
towards the suspension rope until the suspension rope is securely enclosed and the brake shoe
presses the suspension rope into the rope guiding shoe in the end position.
A complete braking or a slipping on the suspension rope can be achieved by regulating the press-
on pressure. Only one hand is needed for the brake regulation and only a slight turning of the screw
spindle for either the 'locked' or 'slip' positions. The transmission of hand force on the screw spindle
is effected with a powerful three-star handle. The rope guiding shoe has a suitably shaped run-in
side that prevents a damage to the suspension rope. The descending harness and the wire rope of
the descender device are secured with the swivel on the descending brake in order to prevent rope
twisting and make it possible to adapt the user's body position to the respective needs.
The descending brake and the descender device must be inspected for perfect condition by the
manufacturer or a competent person after a descending distance of 1000m or at least once a year.
The spindle nut and the spindle bearing in the brake shoe must be inspected for smmoth operation
and greased as part of this inspection.
Note: The descending brake must always be stationed at the upper descending point and only used
in combination with the descender device. A use without the descender device can result in
uncontrollable descending speeds where braking can then cause an overloading on the suspension
ropes or safety harnesses.
5. Maintenance, storage, transport and repair
If necessary, clean descender device and descent rope after use with a damp cloth.
Do not use solvents.
Air-dry only, i.e. do not dry close to fire or other heat sources. Store descender device and descent
rope in dry, ventilated rooms, protected from sunlight. To avoid damages during storage or
transport the equipment should be stored in an equipment bag or transport box. Avoid exposure to
excessive moisture, heat, chemicals, acids, corrosive fluids and oils. If unavoidable, please contact
the manufacturer.
If the equipment needs to be disinfected, please also contact the manufacturer.
Repairs may only be executed by the manufacturer or a person authorized by the manufacturer
strictly following the instructions for repair.
Rescue devices that are part of a fixed installation on the workplace and that are kept in position
between the inspections, have to be protected against environmental influences in a suitable way
(f.e. in a rescue barrel).
Rescue equipment shall be stored in a clearly marked area and be readily accessible for rescue
purposes.
Equipment, which is damaged or in need of maintenance, should not be stored in the same area as
usable equipment. Prior to using equipment which has been stored for long periods (greater than
one year) of time, a detailed inspection should be performed by a competent person. heavily soiled,
wet or otherwise contaminated equipment should receive proper maintenance (e.g. drying and
cleaning) prior to storage.
6. Inspection of the rescue equipment
Equipment shall be inspected by the rescuer before each use and additionally by a competent
person other than the rescuer at intervals of no more than one year and after reaching the descent
energy W=1,5 x 10
Inspection criteria for the equipment shall be set by the rescuer's organization. Such criteria shall
equal or exceed the greater of the criteria of the standard or the manufacturer's instruction.
Inspection criteria shall be kept current in relationship to changing patterns or conditions of use.
Dry the device if it has become wet during use or during cleaning.
