4. Requirements relating to cables, drives and brakes and to mechanical and electrical installations
4.1.1. All measures shall be taken in line with the latest technological developments: to avoid cables or their attachments breaking, to cover their minimum and maximum stress values, to ensure that they are safely mounted on their supports and prevent derailment, to enable them to be monitored. 4.1.2. It is not possible to prevent all risk of cable derailment; measures shall be taken to ensure that cables can be retrieved and the cableway installations shut down without risk to persons in the event of derailment. The drive system of a cableway installation shall be of a suitable performance and capability, adapted to the various operating systems and modes. The cableway installation shall have a standby drive with an energy supply which is independent of that of the main drive system. A standby drive is not, however, necessary if the safety analysis shows that people can leave the vehicles and, in particular, towing devices easily, quickly and safely even if a standby drive is not available. 4.2.3.1. In an emergency, it shall be possible to shut down the cableway installation and/or the vehicles at any moment, under the most unfavourable conditions in terms of authorised load and pulley adhesion during operation. The stopping distance shall be as short as the security of the cableway installation dictates. 4.2.3.2. Deceleration values shall be within adequate limits fixed in such a way as to ensure both the safety of the persons and the satisfactory behaviour of the vehicles, cables and other parts of the cableway installation. 4.2.3.3. In all cableway installations there shall be two or more braking systems, each capable of bringing the cableway installation to a halt, and coordinated in such a way that they automatically replace the active system when its efficiency becomes inadequate. The cableway installation's last braking system shall act as close as possible to the traction cable. These provisions do not apply to drag lifts. 4.2.3.4. The cableway installation shall be fitted with an effective clamp and locking mechanism to guard against premature restarts. The control devices shall be designed and constructed so as to be safe and reliable, to withstand normal operating stresses and external factors such as humidity, extreme temperatures or electromagnetic interference and so as not to cause dangerous situations, even in the event of operational error. Suitable facilities shall be provided to enable operational staff to communicate with one another at all times and to inform passengers in case of emergency.
