3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
cableway
item of children’s playground equipment whereby children can travel on or along a cable under the force of gravity
Note I to entry: See Figure 1
3.2
hanging type cableway
cableway equipped with a suspension assembly which includes a grip for the user
3.3
seating type cableway

starting point
area in which the user can reach the grip or seat and set the equipment in motion
area of travel
area in which the user can travel freely
3.6
terminus
area furthest away from the starting point that the user can reach by travelling across the area of travel
3.7
(raveller
moving part that, by influence of gravity, moves the user along the cable
Note I to entry: See FIgure 1.
A.l Principle
When using cableways. different speeds have an effect at the end of the travelling distance, Ic. the stop at the terminus. High speeds cause the user to swing outwards at the terminus, as illustrated in Figure 4. To test the effectiveness of the impact attenuation and the outward swing, the seat or grip is loaded with a mass of 69,5 kg (see EN 1176-1:21)17, Annex A) and set in motion from the starting point to the terminus. The seat or grip is monitored to ascertain whether the traveller stops in an impact attenuating manner and the angle of swing Is recorded.
A.2 Apparatus
Mass of 69,5 kg.
A.3 Procedure
l.oad the seat or grip with the mass (A.2). Start the traveller in motion at the starting point by pulling the suspension element to an angle of 300 against the direction of travel and releasing.
Visually assess whether the traveller is progressively slowed down and stopped and measure and record the angle of swing.
