AS 19202.1:2021 – Summer toboggan runs Part 1: Safety requirements and test methods (ISO 19202-1:2017(ED.1.0)MOD).
5.2 Toboggan
5.2.1 General
The passenger compartment shall be designed in such a way that the user is properly seated and kept on the toboggan e.g. hackrests, armrests). Handles, seat with lateral reinforcement and footrests shall also be provided on the toboggan.
It shall be ensured that the users can safely operate the toboggan as it is intended.
The toboggan shall be designed in such a way that users cannot reach hazardous parts when conducting themselves as intended.
The toboggan shall be designed in such a way that no unexpected forces occur as a result of changes in transverse gradients, curves, crests or depressions and as a result of wear.
It shall be ensured that the toboggan is decelerated if the user is not using the toboggan control elements. II this cannot be realized for all operating conditions, at least one user-independent brake shall be provided in the entrance and/or exit zone.
A backrest shall be provided for uphill passengers facing in driving direction if inclines exceed 35 %.
5.2.2 Toboggan for rail-guided summer toboggan runs
The system shall he designed to prevent derailment of the toboggans.
An emergency running device shall ensure a safe-guided toboggan all the time.
Restraint systems arc mandatory for each user and shall be verified (e.g. by calculation, tests and certificates).
Restraint systems shall be designed In such a way that the devices cannot open at purely or unintentionally.
The restraint system shall be designed In such a way that crushing or trapping of body parts Is not possible.
The toboggan shall be provided with a shock-absorbing device, which shall be effective at any part of the downhill track. The design basis for shock-absorbing devices and restraint system shall be the maximum speed. An analysis of the loads expected to act on the users is mandatory.
The restraint system shall be able to withstand such loads.
Passing over or under the shock-absorbing devices in a collision shall be prevented by the system’s design devices.
5.2.3 Toboggan for tub-guided summer toboggan runs
Thb-guided toboggans may be used without restraint system because the tohoggans are not force- guided and the user can overturn with the toboggan.
The toboggan shall be provided with a shock-absorbing device, which shall be effective at any part of the downhill track. Shock absorbing may also be ensured by the toboggan design and/or selecting appropriate material for the toboggan. The shock-absorbing device shall be designed for maximum speed. An analysis of the loads expected to act on the users is mandatory.
Running over of toboggans shall be prevented.
The accelerations occurring from the toboggan’s swinging movement shall also be calculated for toboggan, tub and substructure.
The layout of the track shall be such that a user can safely travel along the track at an adequate speed.
5.3.4 Visibility down the track and braking distances
5.3.4.1 RaIl-guided runs
a) The visibility down the track shall be chosen as a function of the braking distance plus a reaction time of about I s, but shall be at least 20 m,
b) At top speed, the braking distance resulting from a “dry emergency braking situation shall be no more than 10 in.
c) At top speed, the braking distance resulting from a wet” emergency braking situation shall be no more than 20 m.
In exceptional cases such as In tunnels and on hilltops, signs requesting the user to brake or to drive slowly shall be used to indicate a reduced range of vision.
5.3.4.2 Tub-guIded runs
a) The visibility down the track shall be chosen as a function of the braking distance plus a reaction time of 1 s. but shall be at least 25 in.
b) At top speed, the braking distance resulting from a “dry emergency braking situation shall be no more than 15 m.
c) At top speed, the braking distance resulting from a wet” emergency braking situation shall be no more than 40 rn
For runs which can also be operated In wet” conditions, the range of vision should beat least 50 in. In exceptional cases such as in tunnels and on hilltops, signs requesting the user to brake or to drive slowly shall be used to Indicate a reduced range of vision.
5.4 Entrance and exit area
S.4.1 General
These areas shall he designed such that the operation .and the entry and exit of the user can be achieved in a safe and smooth manner.
The station area prohibited for the users shall be secured against unauthorized access. Harriers, stairs, etc., shall be designed in compliance with national regulations.
Walkways shall be even and slip-resistant.
