3.1.3 Electrical toboggan run
Electrical toboggan run refers to a facility, through which, a manned toboggan does not
completely rely on gravity during the sliding process on a fixed track and uses electric
power as the power for sliding.
3.2 Average Inclination of Summer Toboggan Run
Average inclination of summer toboggan run refers to the ratio of the overall height
difference of the summer toboggan run to the horizontal projection of the total extended
length of the summer toboggan run.
3.3 Accessory of Summer Toboggan Run
Accessory of summer toboggan run refers to other facilities required for summer
toboggan sports in addition to the main structure of the summer toboggan run.
NOTE: it includes: toboggan for summer toboggan run, lifting system, label, marking,
reflector, safety net, supporting structure, lighting equipment, power distribution
equipment and electrical control system, etc.
3.4 Summer Toboggan Sports
Summer toboggan sports refer to the movement of a toboggan controlled by the
passengers to slide from the upwards to the downwards along the summer toboggan
run.
3.5 Toboggan for Summer Toboggan Run
Toboggan for summer toboggan run refers to a manned device which has a braking
device and uses summer toboggan run for sliding.
3.6 Lift Rail
Lift rail refers to a rail erected between the bottom station area and the top station area
and sends toboggan to the top station area.
3.7 Downhill Rail
Downhill rail refers to a rail erected between the top station area and the bottom station
area and used to support a manned toboggan to slide from the top station area to the
bottom station area.
3.8 Lift for Summer Toboggan Run
Lift for summer toboggan run refers to a system which sends a toboggan along the lift
rail from the bottom station area to the top station area. It is composed of lift rail and
5.1.4 The route of summer toboggan run should be close to the original ground, avoid
a large area of exploitations or fills and reduce the influence on vegetation and the
original landform.
5.1.5 The route of summer toboggan run shall avoid crossing roads and canyons, etc.
When it is impossible to avoid, reliable safety facilities shall be set up.
5.1.6 The layout of the station area shall make it easy for the gathering and dispersing
of personnel.
5.1.7 The downhill rail should be erected in a mode of connecting straight roads,
transitions and curves in accordance with the terrain.
5.1.8 The design of summer toboggan run shall specify the design service life of the
whole machine and its main components. The service life of the whole machine shall
be not less than 35,000 h.
5.1.9 The maximum load of a single-passenger toboggan for summer toboggan run
shall be calculated as 1,000 N. The maximum load of a multi-passenger toboggan with
above 2 passengers (including 2 passengers) shall be calculated as 750 N  the
number of passengers.
5.1.10 In addition to stress calculation for important shafts and important welds of
summer toboggan run, the calculation of fatigue strength shall also be performed, and
both shall satisfy the corresponding safety factors. For important shafts that are difficult
to be disassembled, they shall be designed for infinite life.
5.1.11 When medium carbon steel (such as: 45 Steel and 40Cr Steel) are used, the
important shaft materials shall be quenched and tempered.
5.1.12 Under normal operating conditions, the cumulative operating life of the various
types of wearing parts shall be not lower than 6 months. Under normal operating
conditions, the cumulative operating life of important stressed parts (such as: important
pins and traction wire ropes) shall be not lower than 12 months.
5.1.13 Under normal operating conditions, the maximum allowable deformation of the
track and supporting structure of summer toboggan run shall be 1/300.
5.1.14 When the chute and track are made of stainless steel, the thickness of the
material of the main stressed parts shall be not less than 2 mm; when carbon steel is
used, anti-corrosion treatment shall be conducted. The thickness of the opening
section of the main stressed parts shall be not less than 5 mm; the thickness of the
closed section shall be not less than 3 mm. When glass fiber reinforced plastic is used,
the thickness of the material of the main stressed parts sha...
