4.1 Basic requirements

4.1.1 The design documentation for an amusement ride overhead shall include at least the design specification, design calculations, operating and maintenance instructions and design drawings, risk assessment report, design verification test plan, nameplate, list of major load-bearing components and important welds, etc. The above information shall be retained at least until the amusement facility to which the design documents relate is scrapped.

4.1.2 The list of main load-bearing components and important welds is to be determined by methods such as Failure Mode and Effects Analysis (FMEA) or Fault Tree Analysis (FTA).

4.1.3 During the design phase of an amusement ride overhead, a risk assessment shall be conducted in accordance with GB/T 34371.Risk assessments shall also be conducted for products requiring modification or those intended to continue in use beyond their service life. This risk assessment shall consider the load-bearing structure and components, electrical control system and components, equipment operating environment, obstacles around the equipment, human factors, unexpected factors, and

4.3.1 Vehicles (cabins) shall have signs indicating the vehicle number, passenger capacity, and prohibition of overloading in prominent locations.

4.3.2 The seats shall be securely fixed to the passenger structure. The strength of the seats and their fixing structures shall be checked.

4.3.3 Non-enclosed vehicles (cabins) shall be equipped with passenger restraint devices that cannot be released by passengers themselves.

4.3.4 Horizontal push-type flying cinema rides with an operation height of 2 m or above and a risk of falling personnel shall at least meet the following requirements.

a) When only seat belts are used. the seat belts shall not be opened by the passenger on their own; the seat belts shall be able to tighten automatically; the seat belt locking shall be interlocked with the start; the seat belt locking shall be redundant; and handrails shall be provided for passengers to grasp.

b) When only passenger restraint devices other than seat belts are used. the passenger restraint device shall not be opened by the passenger; the locking position shall be adjustable; the locking shall be interlocked with the start; the locking shall be redundant; and handrails shall be provided for passengers to grasp.

c) When there is a risk of a passenger falling from the front of the seat. An effective barrier structure shall be provided in front of the passenger seat. When a crotch webbing is used to prevent a passenger from falling from the front of the seat, the webbing shall meet the load-bearing capacity and width requirements of the seat belt.

4.3.5 When operating at a height of 1 m or above and there is a risk of falling, closed cabin doors shall be equipped with two locking devices or a single locking device with a safety lock that cannot be opened by passengers from the inside. The opening force that the door can withstand in the locked state shall be no less than 1 kN.

4.3.6 When a vehicle (cockpit) uses automatic doors, the automatic doors shall have anti-pinch measures and emergency opening functions.

4.3.7 Enclosed vehicles (cabins) shall be equipped with ventilation holes and fire extinguishing devices. Window breaker hammers shall be provided. Appropriate signs shall be displayed.

4.3.8 An emergency call button shall be installed in enclosed vehicles (cabins). Triggering the button allows passengers to contact staff. Video surveillance shall be installed in cabins with 4 or more passengers. The video surveillance shall cover all passengers. Video footage shall be retained for at least 10 d.

4.4 Drive and transmission system

4.4.1 When the transmission system fails, the amusement ride overhead shall be in a safe state.

4.4.2 During the start-up and operation of the amusement ride overhead, there shall be no noticeable slippage, and the transmission mechanism shall operate normally. During operation, the entire vehicle must not experience abnormal vibration, impact, heat generation, noise, or jamming.

4.4.3 The drive and transmission systems of bicycle overhead railway type shall at least meet the following requirements.

a) Footrests must be securely installed and comply with the relevant provisions of QB/T 1886.

b) For sprocket and chain drives, a chain guard must be provided, covering at least the top and sides of the chain.

c) For vehicles with both electric and foot-operated drive modes, these shall not interfere with each other. A passenger-operable switch must be provided.

4.4.4 The drive and transmission system of an amusement ride overhead using a rack- driven system shall at least meet the following requirements.

a) Vertical rack-and-pinion meshing drive bogies shall be equipped with a rack-and- pinion height adjustment device or structure to ensure normal rack-and-pinion meshing after wheel wear;

b) When a rack-type vehicle is operating in the transitional phase between rack-type drive and wheel-rail friction drive at the design speed, a gear insertion device shall be installed;

c) For vehicles with both wheel-rail friction drive and rack-rail drive, they shall have an automatic switching interlocking protection function for both rack-rail drive and wheel-rail friction drive modes.

4.4.5 The hydraulic and pneumatic systems shall be able to operate normally within the allowable operating temperature range of the amusement ride overhead.

4.4.6 The hydraulic or pneumatic system used for the operation of safety protection devices shall be equipped with a device to monitor the working status of the system to facilitate observation by operators.

4.4.7 When the pressure of the hydraulic or pneumatic system used for the operation of the safety protection device exceeds the normal operating range, the corresponding safety protection function shall be triggered.

4.4.8 The drive and transmission systems of amusement rides overhead powered by internal combustion engines shall at least meet the following requirements.

4.5 Electrical and control systems

4.5.1 The design and installation of the electrical system shall comply with the relevant provisions of GB/T 5226.1.
