This note contains the necessary information for a correct use of the following
product/s: pulleys.
1) FIELD OF APPLICATION.
EN 12278:2007: Mountaineering equipment - Pulleys. This product is a personal
protective device (P.P.E.) against falls from height; it is compliant with the Regula-
tion (EU) 2016/425.
Attention!
Duetto model complies with the requirements of
VG11.104 for use on steel wire ropes.
2) NOTIFIED BODIES.
Refer to the legend in the general instructions (paragraph 9 / table D): M1; M2;
N1.
3) NOMENCLATURE.
(Fig. 2).
A) Connecting hole. B) Flange (mobile or fixed). C) Pulleys with rotation
system (Fig.1). D) Rotation Pin. E) Auxiliary connecting hole (only where it’s pres-
ent). F) Side plates anti-rotation pin (only when present).
3.1 - Main materials
. Refer to the legend in the general instructions (paragraph
2.4): 3 (flanges, pulleys). Only for model Duetto: 2 (pulleys, pin); 3 (flanges).
4) MARKING
.
Numbers/letters without caption: refer to the legend in the general instructions
(paragraph 5). Numbers/letters with asterisk (*): indication shown depending
on the model.
4.1 - General
(Fig. 3). Indications:1; 4; 7; 8; 11; 12; 13; 14; 30) Usable rope/
accessory cord diameters; 31) Usable cable diameters*; 32) Pictogram indicat-
ing that the device includes pulleys mounted on ball bearings*.
4.2 - Traceability
(Fig. 3)
.
Indications: T1; T3; T8; T9*.
5) CHECKS.
Further to the checks listed below, comply with what indicated in the general
instructions (paragraph 3).
Before each use, verify that: connectors in use work properly and symmetrically.
During each use: make sure that pulley and rope do not lean against, or rub,
sharp edges and abrasive materials.
6) COMPATIBILITY.
This product can only be used in combination with CE-marked equipment: work or
mountaineering equipment such as connectors (EN 12275), ropes (EN 1891 /
EN 892), accessory cords (EN 564) etc.
Attention!
As for the use of the Duetto
model in compliance with the requirements of VG11.104, please refer to the
paragraph 9 and to the figure 11.
6.1 - Ropes and steel cables.
The compatibility of the different models with ropes
and/or steel cables is showed in the table (Fig. 1).
Attention!
Never use the pul-
leys with sheaves in light alloy on metal cables.
Attention!
A rope with a too small
diameter may fit between the pulley and the side plate.
6.2 - Connectors.
To connect the device to the anchor point, use only connectors
equipped with a locking gate.
Attention!
Always insert the connector in the con-
necting holes of all the flanges (Fig. 4.4).
7) INSTRUCTIONS FOR USE.
The pulleys are devices used to reduce the friction when lifting or moving a load.
7.1 - Efficiency.
In the basic configuration the theoretical force (F) necessary to lift
a weight (P) is equal to the weight itself (Fig 5.1). In reality there are frictions that
reduce the efficiency of the pulley and increase the force necessary to actually lift
the weight (F = 1.1 ÷ 1.4 P). If a connector was used instead of the pulley, the
F value would be twice as much as P.
Attention!
Where otherwise specified, the
indicated F values are theoretical.
7.2 - Warnings.
The stress on the anchor point and on the other elements of the
system can increase considerably due to the dynamic movements of the load
during the manoeuvre: verify the overall resistance of the system.
8) USE FOR TENSIONED LINE/Tyrolean (NOT COVERED BY STANDARDS).
1) The anchor points of the working line must be separated from those of the
safety line (Fig. 9.1- 9.2). 2) Prepare an auto blocking device (ex. Rollnlock) on
the safety rope for the autonomous progression (Fig. 9.3). 3) Pay attention to the
stresses generated on the anchor points based on the angle that is created (Fig.
9.5). 4) Pay attention to the inclination of the rope and the consequent speed of
descent (Fig. 10).
9) USE IN COMPLIANCE WITH VG11.104 (DUETTO MODEL ONLY).
The Duetto model is suitable for use in rope courses, in accordance with
VG11.104.
9.1 - Compatibility.
The equipment is compatible with 12mm-diameter, galva-
nized steel wire ropes. The tests have been carried out on the following types of
wire rope: 7x19 wire rope; rotation-resistant wire rope 19x7.
Attention!
Do not
use the equipment on wire ropes with specifications different from those indicated.
9.2 - Installation.
While installing the equipment on the line only use EN 12275
connectors equipped with locking gates, EN 12277 harnesses, EN 566 slings or
lanyards for adventure park that comply with Regulation 2016/425 (Fig. 11.1-
11.2).
9.3 - Clearance distance
(Fig. 11.3). Clearance is the minimum distance below
the anchor point, which has to be ensured in order to prevent the user from com-
ing into contact with the structure, the ground or any obstacle in the event of a fall
from a height. The clearance distance (F) is given by the length of the equipment in
use (pulley - connector - lanyard = L) plus an additional distance of 2.2 m (B+C).
Attention!
Before and during each use it is essential to take into consideration the
value of the clearance, in order to guarantee at all times a minimum distance of
1 m between the user’s feet and the ground or any other obstacle in case of a
fall.
Attention!
Pay attention to the speed of descent (Fig. 10) in order to avoid
hitting any potential obstacle.
Attention!
While in use be careful not to entangle
hair, fingers or anything else on the device; the use of gloves is recommended.
