cableways
For hanging type cableways the grip shall be constructed to ensure that the user can easily release their hold at all times. If the grip is an enclosed loop, it shall not be made from flexible material that could tighten around the user’s arm or hand thus preventing the user from releasing their grip quickly. Enclosed loops shall conform to the entrapment requirements in EN 1176-1:2008, 4.2.7.
The cable height of seating type cableways, C1, shall be 2 100 mm minimum, when measured as shown in Figure 2, except that it may be reduced to 1 800 mm minimum if the moving parts of the traveller are en-closed, are not accessible by the user and there is no possibility of finger entrapment.The cable height of hanging type cableways, C2, shall be 300 mm minimum, when measured as shown in Fi-gure 2.
The falling space and impact area shall be free from obstacles that could cause injury and shall be as shown in Figure 4 and Figure 5. In addition to the requirements given in EN 1176-1, the falling space and impact area shall be provided to a distance of at least 2000 mm to each side of the cableway and to a distance of at least 2000 mm beyond the end of the swinging position, (max 45, end stop compressed) of the grip or seat. The impact area may reduce in width symmetrically from the end of travel to a minimum overall width of 2 000 mm (see Figure 4). The impact attenuating surface within the impact area shall at least conform to the minimum values for a critical fall height of 1 000 mm. For fall heights greater than 1 000 mm, the attenuating properties of the impact area shall be increased proportionately.
NOTE An example of the falling space is given in Figure 6.
Where starting platforms, together with their access ramps, are constructed of materials that yield, including timber and metal, they may be provided without an impact attenuating surface up to a maximum free height of fall of 1 000 mm.AS 4685.4 pdf free.
