Cableways shall conform to EN 1176-1 unless otherwise specified in this part of EN 1176.
4.2 Framework and fixing points for the cable
Framework and fixing points for the cable shall be designed to withstand the computed loads (static and dynamic) transmitted by the cable, in accordance with EN 1176-1.
There shall be an adjusting device so that the correct sag can be maintained for the life of the cable.
4.3 Calculation of forces acting on the cable of a cableway
The cable shall be designed so that it can withstand the forces acting upon it according to EN 1176-1:20 17, Annex A.
4.4 Stops
When tested in accordance with Annex A, the stop at the terminus shall progressively slow down the traveller until it stops and the suspension element shall not swing through an angle of more than 45°, as shown in Figure 4.
NOTE This test includes an allowance for starting speed.
4.5 Traveller
The traveller shall be constructed so that it cannot slip out of place and the sides are closed to prevent any access by the user to moving parts from the side.
Openings for the cable may allow the 8 mm finger rod (see EN 1176-1:20 17, Figure D.10) to pass through but the rod shall not get squeezed between any moving parts when it is inserted by the length of 70 mm.
There shall be only one traveller on the same cable.
The traveller and suspension element shall be designed such that it does not cause damage to the cable during use.
4.6 Suspension assembly
For seating type cableways rigid suspension elements shall not be used.
If a flexible suspension element is used it shall be designed to prevent risk of strangulation.
If a pulling device for the traveller is provided it shall be designed to prevent risk of strangulation.
