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 shall be not less than 8 mm. The main load-bearing rail of monorail summer toboggan run shall be made of metal materials. The rail width shall be not less than 150 mm; the material thickness shall be not less than 4 mm. (such as: uneven settlement, cracking and loosening, etc.) that would affect the normal operation of the amusement facility. 5.1.29 The structure design of summer toboggan run shall consider temperature stress caused by changes of the ambient temperature, and the corresponding temperature deformation shall be able to be released. 5.1.30 Chute summer toboggan run shall set up pinboards in the straight section, so as to offset the influence of thermal expansion and contraction on the overall supporting structure of the summer toboggan run. In addition, it shall also be ensured that under the condition of maximum shrinkage, there is no pull-off phenomenon at the lap joint. 5.1.31 Pipeway summer toboggan run shall set up expansion joints in straight sections and curves, so as to offset the influence of thermal expansion and contraction on the overall supporting structure of the summer toboggan run. In addition, there shall be a device to prevent the pipeways from being disconnected from each other after thermal expansion and contraction. 5.1.32 The supporting structure of the summer toboggan run shall effectively fix the summer toboggan run and prevent it from being deformed. The supporting structure shall comply with the following conditions: a) The supporting structure shall have sufficient rigidity and strength to satisfy the requirements of use; b) When ferrous metal materials are used for the supporting structure, anti- corrosion treatment shall be conducted; c) The supporting structure and the lower foundation shall be firmly fixed. 5.1.33 The supporting structure and the lower foundation shall be fixed by modes of pre-embedding, anchoring and bolt connection, etc. 5.1.34 When the height of the supporting structure is greater than 1 m, safety nets shall be installed on both sides of the summer toboggan run, and a walkway for maintenance and rescue shall be installed; or, when safety net is installed on one side, safety passage with guardrails shall be installed on the other side; or, safety passages with guardrails shall be installed on both sides of the summer toboggan run. When safety passage with guardrails is installed on one side, the passage shall be installed outside the arc section. Safety nets and guardrails shall comply with the stipula.......
