1. Position and Preconditions for Implementation of Operation Tests

1.1 Responsible Party

1.2 Preconditions (must be satisfied before test startup)

1. Foundation acceptance is qualified; anchor bolts and anchorages are fully tightened; ground bearing capacity for mobile equipment is confirmed acceptable.
2. Steel structures are installed in position; final tightening of high‑strength bolts and non‑destructive testing of key welds are finished with complete documentation.
3. Mechanical transmission parts including bearings, chains and gears are assembled and lubricated; hydraulic / pneumatic pipelines are assembled without leakage; safety valves and overflow valves are calibrated.
4. Electrical system wiring, earthing, lightning protection, sensors, limit switches, interlocks and emergency‑stop circuits are completed.
5. Passenger‑carrying devices, safety belts, safety lap bars, latches and restraining devices are fully assembled and commissioned; safety clearances are rechecked.
6. Safety guard fences, platforms and emergency rescue devices are in place; the site is cleared; the test area is isolated with warning measures and emergency personnel on standby.
7. Design drawings, calculation documents, operation‑maintenance manuals and load parameters are clear; specifications for standard counterweights are defined.

Operation tests shall not be carried out with existing defects. In case of abnormalities during testing, stop the machine for troubleshooting immediately. The full set of working‑condition tests shall be restarted only after faults are eliminated.

2. Core Test Working Conditions: No‑load, Half‑load, Full‑load and Eccentric‑load

Load simulation: Standard counterweights shall be adopted; 75 kg is commonly used for single‑passenger simulated load. Both minimum and maximum passenger‑load conditions shall be covered to assess passenger‑carrying devices and restraining devices.

2.1 No‑load Operation Test

1. Smooth start‑up, direction change and braking without creeping or jamming;
2. No abnormal vibration, impact or abnormal noise in transmission system; normal temperature rise of motors, reducers and bearings;
3. No leakage in hydraulic and pneumatic systems; pressure parameters conform to design requirements;
4. Accurate and reliable action of limit positions, travel switches, interlocks, emergency stops and various protective devices;
5. No interference in running tracks of passenger‑carrying devices; safety clearances comply with drawings;
6. Normal control‑system signals, logic and alarm functions.

2.2 Half‑load Operation Test

2.3 Full‑load Operation Test

1. No permanent deformation shall occur on steel structures, frames, lifting points and connecting bolts;
2. Smooth start‑up and braking without abnormal impact or jitter; temperature rise and pressure of motors and hydraulic systems within allowable ranges;
3. Braking distance and deceleration comply with design requirements;
4. Normal locking and interlocking functions of passenger‑carrying devices and restraining devices (safety belts, safety lap bars);
5. Reliable activation of limit, overspeed and overload‑protection devices.

2.4 Eccentric‑load Operation Test (high‑risk key working condition)

Examples: Full‑load on cabins of one side while light‑load on the other side; some cabins fully loaded and others unloaded.

Eccentric load is a key inducement for many amusement‑ride failures. Complete records of this working condition must be submitted for supervision‑inspection.

3. Special Supporting Tests (conducted together with operation tests)

3.1 Special Test for Passenger‑carrying System

1. Perform tests respectively with three types of simulated loads: minimum‑weight passenger, standard 75 kg load and maximum‑weight passenger; no less than 3 cycles for each working condition.
2. Inspect the status of rigid / flexible structures of passenger‑carrying devices; idle travel and closed position of safety lap bars; latching, unlocking and interlock feedback of latches; external locking‑status indicators; reliable connection between restraining devices and steel‑structure frames.
3. For flexible passenger‑carrying devices (safety harnesses, webbing slings): Focus on checking intact webbing, no slippage of connecting parts and no abnormal deformation under load.

3.2 Special Test for Safety‑protection Devices

3.3 Additional Tests for Special‑category Equipment

1. Gyro‑type and self‑control‑aircraft‑type rides: Repeated boom lifting tests to check jitter, impact and limit effectiveness during lifting;
2. Slide‑track rides: Braking performance and running tracks of carriages;
3. Bungee and zip‑line rides: Special tests for flexible passenger‑carrying devices, slings, hanging points and recovery systems;
4. Ferris‑wheel and sightseeing‑vehicle rides: Key assessment for cabin suspensions, hanging points, rotary driving and band‑brake performance under eccentric‑load conditions.

4. Acceptance Criteria for Qualified Tests

1. Complete mechanical motion sequences; smooth start‑up, speed change, direction change and braking
