Inspection Before Use - Tractel Group Stopfor K Instructions D'emploi

The Stopfor™ K, KS / Stopfor™ B, BS move freely along the
anchor line. In the event of a fall, the device swings over, thereby
bringing the anchor line into contact with the shaft's upper part. The
shaft revolves inside the device and then grips the anchor line.
The Stopfors™ KM, KSM BM and BSM move manually along the
belay support. When a fall occurs, the device pivots to bring the
belay support into contact with the upper part of the cam. The
cam turns inside the device and grabs the belay support.
The system is comprised of two flanges articulated around the
camshaft (Fig.8 page 2, Q). The device is opened by pivoting the
mobile flange (Fig.8 page 2, R). The pressure of the shaft is
GB
maintained on the anchor line by the shaft's spring (Fig.8 page 2,
S). As soon as the anchor line is in position and the connector
has locked the two flanges, it is no longer possible to open the
device; the anchor line is thus imprisoned inside.
The Stopfors™ KS, BS, KSM, BSM are equipped with an anti-
turnover system (Fig. 8 page 2, T) ensuring the Stopfor™ a
correct operating direction on the belay support. If the Stopfor™
is presented upside down with respect to the vertical belay
support, the anti-turnover system blocks the jaw (Fig. 8 page 2,
Q). This prevents installation of the Stopfor™ on its belay
support.
The Stopfor™ KM, KSM, BM, BSM are equipped with a
reinforced spring which permanently locks the Stopfor™ on the
belay support. This function is generally used for interventions on
slanted surfaces. With the device locked on the rope, the user is
required to manually move the Stopfor™ when descending.
For enhanced comfort when moving upward, the belay support
should be ballasted by applying a coil or by placing a weight of
1 kg max. at the lower part.
4. The lanyard (Fig.5 page 2, L)
Several types of lanyard are available:
• Stopfor™ A: 0.3 m or 0.6 m length lanyard
• Stopfor™ S/M: 0.3 m 0.6 m or 0.9 m length lanyard.
• Stopfor™ K, KS, KM, KSM / Stopfor™ B, BS, BM, BSM:
0.3 m lanyard. Removable lanyards, codes 42222 or 42232
• Stopfor™ AP: 0.3 m or 0.6 m length lanyard
• Stopfor™ P: 0.3 m.
5. The connectors (Fig.6 page 2, B)
The breaking strength of the connectors supplied with the
lanyard is greater than 22 kN.
1. Anchorage to the structure (Fig.6 page 2, A)
The anchor line is fixed to the anchoring point with a buckle
and a connector. The anchoring point must be able to resist a
minimum of 10 kN.
NB : The anchorage point may be strap, strength 10 kN.
The anchoring point must always be situated
Stopfor™ S, A, AP, P, M
2. Configurations of assembly
The K, KS, KM, KSM, B, BS, BM, BSM, S, A, AP, M, P Stopfor™
models should only be assembled on a vertically suspended
anchor line or where the maximum angle with the vertical is only
30°. In actual practice, the user shall respect this condition by not
moving away from the suspension point's vertical by a distance
greater than half the height from the suspension point to the level
of his plane of movement.
• For example, the user climbs up vertically (0° +/- 30° in relation
to the vertical) onto a metal structure. When the anchor line is
positioned in front of him, the user is linked to the Stopfor™ by
a 0.3 m, 0.6 m or 0.9 m lanyard, depending on the type of
Stopfor™ used (Fig. 10 page 78). For this configuration, use K,
10
Installation
WARNING
above the operator.
KS, B, BS, S, A, AP, P Stopfor™ models.
• When the anchor line is positioned behind or facing the user, he
is linked to the Stopfor™ by a 0.3 m, 0.6 m or 0.9 m lanyard
(depending on the type of Stopfor™ used. Fig. 11 page 78).
The K, KS, B, BS, S, A, AP, P Stopfor™ models are to be used.
• When the user climbs up a ladder, the anchor line is placed
behind or facing him and he is linked to the Stopfor™ by a
0.3 m, 0.6 m or 0.9 m lanyard (depending on the type of
Stopfor™ used. Fig. 12 page 78). The K, KS, B, BS, S, A, AP,
P Stopfor™ models are to be used.
• The user works on a roof deck, his belay support is positioned
horizontally; he can connect his Stopfor to the harness behind
him or facing him with a 0.30 m lanyard. For this case, use a
Stopfor™ K, KS KM, KSM, B, BS, BM, BSM (Fig. 14 page 78).
• The user works on a slanted roof; his belay support is
positioned vertically with an angle less than 30°; he can
connect his Stopfor to the harness behind him or facing him
with a 0.30 m lanyard. For this case, use a Stopfor™ KM, KSM,
BM, BSM, M (Fig. 14 page 78). With a 0.30 m, 0.60 m or 0.90 m
lanyard, use Stopfor™ M (Fig 15 page 78).
3. Configurations of assembly with the AP Stopfor™
• The anchor line is vertical (0° to 30° in relation to the vertical).
Once the parking brake has been activated, the user can work
suspended. The Stopfor™ retains the user and ensures its role
as fall arrester (Fig. 13 page 78).
WARNING
No slack must be made on the anchor line between
the anchoring point and the Stopfor™.
It is thus essential to ensure that it is of sufficient length.
4. Clearance (Fig.A last page)
The clearance must be at least equal to the height of the fall
L = L1( lanyard length: 0.3 m, 0.6 m or 0.9 m) + L2 (braking
distance 1m) + L3 (lanyard length: 0.3, 0.6 or 0.9 m) + 1 m for
safety.
5. Operating environment
• Conditions found on open air sites
• Temperatures ranging between -40°C and +60°C [-40°F and
+140°F]
• Marine environment conditions
• For any work involving product-ejection (painting, sandblasting,
etc.), it is essential to protect the device against any such
product penetrating inside the Stopfor™.
6. Rescue operations
A study must be carried out before use in order to define the
emergency operations to be implemented and the human
resources and equipment required for rescuing an injured person
within 15 minutes in the event of a fall controlled by the
Stopfor™. Any period longer than this will endanger the life of the
person.

Inspection before use

To be verified:
• that neither the casing nor the flanges are deformed;
• the visual state of the anchor line and the lanyard;
• the blocking efficiency of the Stopfor™ fitted onto the anchor
line: tug sharply on the device in the opposite direction to that
indicated by the arrow on the casing;
• the loosening of the jaw and the movement of the Stopfor™ on
the anchor line by pivoting the lever upwards;
• the system's installation conditions (see "Installation" chapter);
• the correct orientation of the Stopfor™ on the anchor line;
• the state of the harness and connectors' associated
