EN 13223, EN 13243, EN 13796-2, EN13796-3. 5.2 Safety principles 5.2.1 General The safety principles set out in EN 12929-1 apply. In addition, the following hazard scenarios and safety requirements relative to the scope of this European Standard shall be taken into account. 5.2.2 Hazard scenarios
The following events may lead to hazardous situations that may be avoided or limited by the safety requirements of this European Standard: a) overloading of the carrier; b) exceeding the limits of use permitted by the manufacturer; c) damage caused by ageing, corrosion, wear, fatigue or deformation; d) hooking up and impact (carrier with carrier, carrier with people, carriers with ropes, stations, line structures and external objects); e) derailment and deropement when carrier passes; f) derailment or instability of the carrier; g) failure of the haulage rope or carrying hauling rope where a grip is attached; h) failure of the attachment or detachment of a grip; i) inadequate resistance to slipping and pull-off of a rope grip; j) faulty door operation (unexpected opening, slamming shut); k) inadequate protection against passengers and any element
falling out of the carrier; l) inadequate positioning and difficult access for the maintenance and evacuation personnel; m) fire. 5.2.3 Safety measures The safety measures to be taken to eliminate the hazard scenarios listed in 5.2.2 are the following: a)
checking of the load or limiting the area available to each passenger and systematically
informing the passengers of the maximum authorized load;
b) establishment of an operating manual defining the limits of use;

e) design to allow unrestricted passage of the grips past the rope-catchers; f) requirements relating to the guiding and stability of the carriers; g) adequate design of the grip to limit the risks of fatigue failure of the haulage rope or carrying hauling rope; h) monitoring the attachment and detachment of the carriers, catching a carrier not properly attached to the rope,
i) monitoring during operation of the gripping force, or of a value representative of this force, of detachable grips j) design of fixed grips to facilitate their systematic displacement without upsetting the adjustment of the spring force; k) periodic checks during operation; l) limiting the effect of an impermissible reduction in the gripping force of the grip; m) monitoring the closing and locking of the doors prior to departure of the carrier; monitoring of the position and speed of the carriers prior to unlocking and opening of the doors, limiting the closing force of the doors, fitting the edges of the doors with soft material; n) use of an efficient safety bar on chairlifts, minimum height of backrests and sides, selection of non-slip materials; o)
use of handholds and anchorage points for PPE against falls from a height; p)
use of positions and access allowing personnel to carry out maintenance and evacuation operations; q) selection of suitable materials to limit the risks of fire. 6 Basic requirements 6.1 Technical documents The following technical documents shall be supplied: 6.1.1 List of safety components A list of all the safety components deemed necessary through a safety analysis shall be drawn up. 6.1.2 Drawings and parts lists 6.1.2.1 General arrangement drawings of the carriers with indications of the main dimensions. 6.1.2.2 Detail drawings with lists of parts and indications of the materials in accordance with 6.4 for:  all the safety components

(1) and
of a wind pressure q = qref Ce (Ze) cd [kN/m2]
(2) In the absence of any verification, the wind pressure q shall be taken as 0,25 kN/m2 for wind actions during operation and 1,2 kN/m2 contrary to the requirements of EN 12930 for wind actions when not in operation. b) In the absence of any verification from wind tunnel tests or numerical simulations, the following coefficients shall be used: 1) For cabins:  sharp edged cf = 1,6  with rounded edges
cf = 1,6 – 2 lr
Key r
is the radius of the edge [m] l
is the cabin length [m]
Figure 2 — Geometrical data of the cabins 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: 
empty chair
cf Aref = 0,2
+ 0,1n [m2]  occupied chair
cf Aref = 0,4 + 0,2 n [m2] 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°, 45°, 90°, 135° and 180° to the direction of travel, both under operating conditions and when not in service.

MY = ± 100 N.m per person; b) without sway damper acting at the joint axis:
MY = ± 25 N.m per person. 6.2.10 Torsional moment (MZ) Moment around a vertical axis due to forces acting in the horizontal plane. For bicable aerial ropeways, the following values shall be used:
MZ = ± 50 N.m per person 6.2.11 Force due to impact on guides (HY2) 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.

The characteristic values shall be verified. 6.2.13 Force due to the action of the on-board brake (QF) Dynamic force caused on the carrier by the action of the on-board brake following a failure of the haulage rope. This force shall be determined by means of a recognized calculation method. 6.2.14 Longitudinal force due to the passengers (HX1) Dynamic force exerted in the direction of travel by the passengers on the outside and intermediate carrier walls, the doors, the seats or the rails. For carriers with a capacity of more than 40 persons, this force HX1 shall be determined on the basis of the useful load of the carrier or of the compartment taking into account the maximum deceleration due to the action of one or other of the brakes.
This value shall not be less than 5000 N/m For carriers with a lower capacity, this value may be reduced by the following formula: HX1 = 5000 – 100x(40-n) [N/m] (3) where n is the number of standing passengers transported in each compartment of the carrier. This force is applied 1,10 m above the floor in the absence of a rail.
If there is a rail, reference shall be made to 11.2.1.2 and 12.1.2. 6.2.15 Transverse force due to the passengers (HY1) Dynamic force exerted by the passengers on the carrier walls, doors, seats and rails transverse to the direction of travel. For carriers with a capacity of more than 40 persons, the value to be used shall be:
HY1 = 2500 N/m For carriers with a lower capacity, this value may be reduced using the following formula: HY1 = 2500 – 30x(40-n)
[N/m] (4) where n is the number of standing passengers transported in each compartment of the carrier. This force is applied 1,10 m above the floor in the absence of a rail.
If there is a rail, reference shall be made to 11.2.1.2 and 12.1.2. 6.2.16 Snow and frost actions Snow and frost actions shall be determined in accordance with EN 12930. a) snow and frost actions may produce the following effects on the carriers:

be given in the operating manual. 6.2.17 Force due to impact against buffers (AX)
The forces due to the impact of a carrier against the buffers in a station during normal operation shall comply with the specifications of EN 13223. 6.2.18 Action caused by the gradient of the ropes (FN) The effect of the gradient of the ropes on the grips during operation shall be taken into account. 6.2.19 Force transverse to the track (FY) The force transverse to the funicular railway track shall take account of the following influences:  transverse acceleration;  forces resulting from the rope guides;  wind action. With regard to transverse acceleration during operation, particularly when entering and leaving the passing loop, and in curves, a minimum value of 0,10 g shall be taken into account.
Lower values may be allowed if they are verified by measurement or calculation. The values of the forces due to the rope guides (horizontal deviation of the rope due to the rollers at the points and at bends) shall be calculated on the basis of the most unfavourable factors determined geometrically. The dynamic changes in the rope tension during operation (starting, braking .) shall be considered according to the maximum allowable values. Wind actions shall be determined in accordance with 6.2.3. The force FY determined takes into account the swaying forces. 6.3 Verifications 6.3.1 General 6.3.1.1 Verifications by calculation shall be provided to meet the minimum requirements regarding:  static safety;  fatigue strength for components subject to fatigue;  lateral deviation due to wind during operation. 6.3.1.2 Verification shall be carried out using recognized methods and taking into account the material and the surface, thickness and shape of the components. 6.3.1.3 For components that fail mainly because of stability problems (buckling, canting), the safety factors shall be verified by specific calculations.

Static verifications 6.3.2.1 General 6.3.2.1.1 As a general rule, static verifications shall be carried out with the equivalent VON MISES stresses relative to the elastic limit of the material Re or the plastic limit Rp0.2. For aluminium alloys, if the elastic limit is greater than 0,72 Rm, a reduced yield point of 0,72 Rm (Rm = tensile strength) shall be taken into account. 6.3.2.1.2 The stability verifications shall indicate at least the same safety factors as when verifying the static safety. 6.3.2.1.3 The following tables give combinations of actions corresponding to the most current load cases that shall be examined. The safety factors in them shall be met.
They may be reduced by 20 % with a minimum of 1 if the calculations are done by finite element surface or volume modelling. If other load cases are to be examined, as a general rule these safety factors are taken as being equal to:  3 in frequent cases;  2 for cases taking account of the wind;  1,6 in rare cases;  1,2 in exceptional cases. For all the load cases, the most favourable positions of the carrier (for example, maximum and minimum gradients of the track) shall be examined.
