When the handles are arranged on the side of the toboggan, the control handles shall be symmetrically arranged. The handles shall be easy and reliable to operate; pull backward for braking and push forward for acceleration; there shall also be clear signs of operation.

b) For toboggan runs without spacing control, when a toboggan is parked on the track, it is naturally in the braking state, and the toboggan shall not automatically slide downwards on any descending toboggan run except the leap section.

c) For toboggan runs without spacing control, after the toboggan stops in any section of the downhill rail, the toboggan can start to slide down by itself when the braking device is fully released.

d) The braking distance of the toboggan shall not exceed 8 m in any section of the non-leap section of the downhill rail, or, for summer toboggan runs with automatic distance control of the toboggan, the rear toboggan shall be able to automatically decelerate to not higher than the speed of the front toboggan.

5.3.3 The front and rear wheels of the toboggan shall be able to simultaneously contact the chute or the track. For sliding-block toboggan runs, the front block and wheels shall be able to simultaneously contact the track.

5.3.4 The panel of the toboggan should be made of materials with a certain degree of elasticity, such as: rubber and plastics, etc. When other non-elastic materials are used, the front and rear of the toboggan shall be equipped with an elastic buffer device.

5.3.5 The toboggan of pipeway summer toboggan run shall be equipped with safety belts or other effective restraint devices. The safety belts or other effective restraint devices cannot be opened by passengers on their own in non-station areas. The steady wheel of the monorail sliding-block shall have an adjustment mechanism for wear and replenishment.

5.3.6 Pipeway summer toboggan runs shall be equipped with protective devices to prevent the toboggan from derailing or turning over.

Along the summer toboggan run, select a position where the distance from the toboggan seat to the upper obstacles is the smallest; use a tape measure to measure its length. The measurement shall be conducted for no less than 3 times; the average value shall be taken.
