Non-destructive Testing of Funfair Rides

Ensuring the safety and reliability of funfair rides is paramount for operators and visitors alike. We have numerous guides on funfair safety at We Are Tricycle, but an important component of safety checking is Non-Destructive Testing, or NDT. This plays a crucial role in maintaining the integrity of funfair rides and attractions without causing damage to the equipment.

NDT encompasses a variety of techniques used to evaluate the properties of a material, component, or system without causing harm. In this article, we'll explore the basics of NDT and how it applies to the upkeep of fairground rides.

• Visual Inspections: The most basic yet vital NDT method involves inspecting rides visually for any signs of damage, such as cracks, corrosion, or wear and tear. Inspectors may use tools like magnifying glasses or cameras to aid their examination, ensuring rides like rollercoasters maintain their structural integrity.
• Dye Penetrant Inspection (DPI): The DPI method is especially useful for finding surface-level defects in non-porous materials. DPI involves applying a dye to the fairground ride's surface, wiping away the excess, and then applying a developer to draw out the dye from any cracks, making them visible. This is also great for maintaining the aesthetic and functional aspects of your favourite attractions.
• Magnetic Particle Inspection (MPI): MPI is used to detect surface and near-surface discontinuities in magnetic materials. This involves magnetising the part you are inspecting. Magnetic particles are then applied, which congregate at defects and which can be seen under ultraviolet light. This technique is critical for the safety checks of funfair rides with metallic components.
• Eddy Current Testing: Used for inspecting conductive materials, this method detects flaws through electromagnetic induction. Changes in eddy current flow are measured, helping to identify potential issues in the electrical systems or metal parts of rides.
• Radiography: X-rays or gamma rays create detailed images of a ride's internal structure, revealing hidden cracks, voids, or inclusions. This is invaluable for comprehensive inspections, ensuring that even the internal components of complex thrill rides are safe for thrill-seekers.
• Ultrasonic Testing (UT): UT uses high-frequency sound waves to detect internal flaws in materials. The sound waves reflect off discontinuities within the material, and these reflections are analysed to determine the presence and size of internal defects. UT is essential for assessing the condition of critical structural components in fairground rides.

Non-destructive testing is essential for the ongoing safety and maintenance of funfair rides. Whether it's the high-speed excitement of Ferris wheels or the nostalgic charm of carousels, NDT helps keep the magic of funfairs alive and well. By incorporating NDT into regular maintenance schedules, funfair operators can provide a safe environment for families and thrill-seekers to enjoy their favourite attractions without worry.
