AS 19202.1:2021 pdf free download – Summer toboggan runs Part 1: Safety requirements and test methods.
This document specifies the safety requirements for planning of track, design and calculation. manufacturing, erection, testing and commissioning of summer toboggan runs and their components according to C1ause. Those are sports facilities with an inclined guided downhill track, on which the user passes a difference in height by users dependent speed control, to a limited velocity and descending by gravity. Its basic approach is the consciousness that the sledding usually implies for the users a remaining risk, which is comparable with sports activities, e.g. bicycle riding, alpine skiing. rope courses, because
a) active independent actions without supervision are necessary on tracks in order to control descents (distance control and braking), and
b) posture and balance to ensure the balance between centrifugal and gravitational force are required. This document is applicable to summer toboggan runs and major modification to summer toboggan runs and toboggans manufactured after the effective date of publication.

6.2.6 VibratIons occurring In directly passable components
Due to the effect of vibrations in directly passable components such as rails, all resulting internal forces shall be multiplied by a vibration coefficient of = 1,2. If trials, drive tests. etc., reveal lower vibration coefficients, a lower coefficient of 2 = 1.0 to 1.2 may be assumed. Calculation without a vibration coefficient is permitted for:
a) supports or suspensions of directly passable components;
b) soilpressure
c) deformations;
d) stability and safety against sliding.
In certain systems, additional structural measures may be necessary to reduce or dampen inadmissible vibrations (e.g. resonances).
6.3 Strength verification by calculation
6.3.1 General
The limit states resulting from the various actions shall be calculated for the load cases and load combinations stated in 6.2. Proof shall be provided that no limit state is exceeded.
Proof is to be provided that the design value for Internal forces or torques does not exceed the design resistance of the respective component and that ultimate limit states and serviceability limit states are also not exceeded.
The limit states of deformation and stability ol the summer toboggan run shall be determined and verified as maximum deformation can be the most important dimensioning criterion. A positive Influence resulting from the finite element method, second order theory, may be taken Into account.
All verifications shall be provided for the least favourable load case. The permanent, variable and accidental actions, as well as dynamic forces, shall always be assumed to occur In the position and magnitude resulting in the least favourable limit states for the structural and mechanical parts to be analysed.
6.3.2 Toboggan calculation
Toboggans shall he designed considering the self-weight, imposed load and the forces resulting from movement.
