— in 7.6.2.6, the tolerances on the geometry of the chapeau de gendarme drum grooves have been
changed to comply with 7.2.3.1;
— in 9.3, the conditions for verifying the load on one of the wheels of a chassis of a funicular railway
have been clarified, so that they are not limited solely to braking with the on-board brake;
— in 10.1 a), determination of the triggering threshold for the on-board brake in the event of failure of
a haulage rope is clarified;
— in 11.2.1.1, a requirement was added regarding the material used for the glazing of the cabins,
which shall not be dangerous in the event of breakage;
— in 11.4.1.2, a clarification regarding chairs has been added for the transport of persons with
reduced mobility with their specific equipment;
— in 12.1.3, a paragraph has been added regarding accessibility for wheelchair passengers in order to
be consistent with 11.2.1.4;
— in Annex ZA, the table has been supplemented.

6.2.3 Wind action (F )
w
Wind actions on the carriers shall be expressed as overall forces. Account shall be taken of exceptional
wind actions in particularly exposed locations.
EN 12930 defines the wind action in the form of a force:
F = q ⋅⋅c A (1)
w f ref
where
q = q c (Z )c ;
ref e e d
q is the wind pressure;
C is the force coefficient;
f
A is the reference surface for C
ref f.
a) In the absence of any verification, the wind pressure q shall be taken as 0,25 kN/m for wind
actions during operation and 1,20 kN/m contrary to the requirements of EN 12930 for wind
actions when not in operation.
b) In the absence of any verification of the values from wind tunnel tests or numerical simulations, the
following coefficients shall be used:
1) Cabins:
i) sharp edged C = 1,2;
f
ii) with rounded edges C = 0,8.
f
A cabin shall be considered to have rounded edges if the r/l ratio is greater than 0,25 (see Figure 2).

2) For uncovered chairs where the passenger sits facing the direction of travel, where n is the
number of persons per chair, irrespective of the wind direction:
i) empty chair cA = 0,2 + 0,1n [m ];
f ref
ii) occupied chair cA = 0,4 + 0,2n [m ];
f ref
3) For covered chairs, the force coefficients shall be determined with the hood open and closed
under the effect of wind hitting the vehicle at angles of 0°, 90°, and 180° to the direction of
travel, both under operating conditions and when not in service.
Particular account shall be taken of surfaces exposed to the wind of chairs’ additional equipment, if
fitted, (e.g. equipment protecting against the cold, transport equipment, etc.).

6.2.4 Gripping force (FF
Force caused by the spring systems of a fixed or detachable grip.
6.2.5 Opening and closing force (O)
Force caused by the opening and closing of a detachable grip.
6.2.6 Reaction force when entering the station (R)
Dynamic force caused by the guides on a carrier of a unidirectional aerial ropeway with detachable
grips when entering the station.
6.2.7 Reaction force when passing round a sheave (U)
Dynamic force on a carrier of a fixed grip continuous movement aerial ropeway when passing round a
sheave.
6.2.8 Force due to haulage rope support (F )
s
Force caused by a support of a haulage rope in a bicable installation or a funicular railway.
For the haulage rope fixings to carriers of bicable reversible aerial ropeways, account shall be taken of
the force transverse to the rope axis at the fixing entry point.
6.2.9 Damping moment (M )
Y
Moment caused by damping of longitudinal swaying.
In the absence of any verifications, for bicable aerial ropeways, the following values shall be used:
a) with sway damper acting at the joint axis: M = ± 100 N.m per person
Y
b) without sway damper acting at the joint axis: M = ± 25 N.m per person
Y
6.2.10 Torsional moment (M )
Z
Moment around a vertical axis due to forces acting in the horizontal plane.
For bicable aerial ropeways, the following values shall be used:
M = ± 50 N.m per person
Z
6.2.11 Force due to impact on guides (H )
Y2
Dynamic force due to the impact of a carrier of a reversible aerial ropeway on guides.
An impact at the most unfavourable point for the cabin shall be considered, with a value: HY2 = 200 N
per person.
6.2.12 Force due to impacts resulting from the action of the carrier truck brake (H )
X2
Dynamic force caused by the impacts that may occur between the cabin and the line elements (for
example, a rope or shoe) on application of the carrier truck brake following a failure of the haulage rope.
This force shall be determined by means of a proven method.
6.2.13 Force due to the action of the on-board brake (Q )
F
Dynamic force caused on the carrier by the action of the on-board brake following a failure of the
haulage rope
