8. INSPECTION PROCESS

An inspection shall be carried out in the following order:

External inspection:

8.1.1. Inspect the structure:

- Inspect the foundation, supports and their connection.

- Inspect the joints connecting the parts in the system by specialized tools.

- Use nondestructive testing methods (penetration testing, ultrasound, or radiography) to inspect important welding joints such as those of the rail, the support, main bearing structure.

8.1.2. Inspection of the propelling system:

- Maximum linear velocity at the cabin: 45km/h for roller coasters for adults and 16km/h for roller coasters for children.

- Inspect parameters of the propelling system with specialized equipment.

- Inspect insulation resistance of the engine at various voltage levels:

- Inspect the transmission parts of the propelling system, which generates necessary potential energy.

- Inspect the brake systems.

8.1.3. Inspection of cars:

- Inspection of labels in each car, maximum capacity and load.

- Structure of the cars.

- Wheels.

- Riders’ seats.

- Inspect the restraints and seat belts.

- Inspection of the safety mechanism that prevent the axles from breaking, which may results in derailment.

- Inspect the main and spare connections between the cars.

8.1.4 Inspect the station and electrical systems, including:

- The handrails and signs.

- Inspect the roof.

- Inspect the control room

- Inspect the parking floor and access from parking lot to the cars

- Inspect the power supply layout

- Inspect the earthing system: ≤ 4.0 Ω

- Inspect the control circuits.

- Inspect the lighting equipment.

- Inspection of lightning protection system: ≤10 Ω.

- Inspect the compliance with applicable regulations on fire protection.

8.1.5. Inspect the safety systems:

- Inspect the safety lock in the cars.

- Inspect the seatbelts.

- Inspect the alarm system and signalling system.

The result is considered satisfactory if no damage or defect is found, all parts are working as designed and the requirements in section 8.1 are met.

 No-load testing:

- Inspection of insulation resistance of the ride.

- No-load testing shall be run only when external inspection is done and the result is satisfactory.

- Run the ride 3 rounds without load, and then check its parameters and features.

The inspection result is satisfactory if the parameters are corrects, and all functions work as designed without signs of errors.

8.3 Overload testing:

- Test at 110% of normal load.

- Load norm of a car equals its testing load multiplied by capacity.

- Based on distribution of cars, load them to create random imbalance of the train in all 4 directions (front, rear, left, right). Each time imbalance is created, run the ride 3 rounds to evaluate its operation. Pay attention to the parts bearing heavier load.

The inspection result is considered satisfactory if the ride operates stably without signs of errors or damage affecting its safety and cars stop at to correct position.

 Inspection of rescue function:

- Run the ride at 100% of at the positions that are most difficult for the rescue staff. Inspect the removal of the safety parts to take riders back to the station safely.

- Inspect the backup power generator and batteries that are used for removal of safety parts if they are available.
