The cyclical movement of the structures of the rides generates a “fatigue” that accumulates over time and can lead to a breakdown of the weakest part. The weakest part of a welded component is always the weld.

The breakage of a mechanical component often involves a risk for passengers and operators and should be prevented. Periodic inspection of welds is the most commonly used means of checking and preventing this type of problem.

Let’s look at the different types of controls suggested based on our experience.


Depending on the type and age of the ride, the quality of the construction process carried out by the manufacturer, we recommend planning an inspection of the welds most sensitive to fatigue.

Taking into account the indications contained in the use and maintenance manual and the recommendations of your technician, it is possible to inspect different parts of the carousel each time in order to make sure that the structures are still fully efficient.

Although this practice is not yet fully in use in certain countries, in many European countries it is considered as a fully accepted and repeated activity every year in the biggest attractions.

If you plan to sell your ride then it is time to perform a thorough check of the welds and shafts/pins of your ride.

This check will facilitate the sale of your carousel and reduce your liability if problems arise a few months after the sale.

All complete reconditioning operations are always considered extraordinary maintenance and must be performed with care.

A 100% weld inspection is recommended when the ride parts are disassembled. This activity takes place very quickly if performed when the pieces are sandblasted. We also suggest checking all the shafts and pins, especially the roller coaster carriages. At the end of the activities we will deliver you a complete report useful especially if you are planning to sell the ride.

Axels and pins of your ride are important components, especially when they are connected to the passenger unit or when they allow the ride to be safely dismantled.

Many operators tend to underestimate the possible breakdown of these components due to the fact that they are closed or hidden from view. However, these are also important components that must be controlled, especially if they are roller coaster axles or when these shafts connect the passenger unit.

Many operators are not interested in selling and changing their attraction, which is then used for many years. Many therefore wonder if it is really possible that a component of the ride could present cracks and break. They wonder how it is possible for a welded piece to break.

Based on our experience we can say that it is absolutely probable that a mechanical component of a ride begins to present weld cracks and finally that it can break. Breakage occurs due to fatigue due to the number of operating cycles over years and years of use.

The right question is when a break can occur. There is no mathematical answer. We can say that a mechanical component will have a longer life when it has been designed and built well, when the welders who performed the weldings were good and careful and if the manufacturer proceeded to perform quality checks. Only in the last 10/15 years the most careful manufacturers carry out a production cycle with a good quality process, with more careful controls. All rides built over 15/20 years have absolutely a medium/low quality process.


There is an international regulation that establishes the minimum requirements that a technician must have to perform these checks. Technicians with specific experience of rides help you to identify the most sensitive and important points.

The technician must provide the operator with a complete report including images showing that the activity was actually carried out and with what methodology was used.


Before performing a repair, it is necessary to understand the causes of the failure. The repair procedure can also be very complex when the defective component is important for passenger safety. When necessary, it is therefore necessary to carry out a repair project, check the execution and carry out a check when the repair is complete.


Thanks to a long technical and commercial experience, FABBRI RIDES is able to follow you in all these phases identifying problems in time and proposing the appropriate solutions.
