In short: How large amusement rides are calculated, which standard applies in your market, how quality is controlled in manufacture, and how a custom layout is designed.
Large amusement rides are not bought the way small ones are. A 20 m trailer-mounted wheel can be ordered from a catalogue; a 60 m wheel, a coaster or an observation tower is a structure with a calculation behind it, a standard it is designed to, a set of inspection records that prove it was built as calculated, and a layout that had to fit a specific piece of ground.
This section sets out how each of those four steps is done here — the method, the documents produced, and the questions a buyer should ask of any supplier, including us. Nothing on these pages is a claim that a certificate covers the world; where a decision belongs to your local authority, it says so.
Load cases come from the governing standard: dead load, passenger live load, wind at the site’s basic wind speed, braking and emergency stop, plus the dynamic effects that appear once a structure is large enough for them to matter. The model is built in MIDAS, checked for stress and deflection against allowable limits, and iterated until member sizes are within target.
The output is a calculation report that sets out the assumptions, the load combinations and the results — a document your own engineer can review before manufacturing starts.
Three words get confused in almost every inquiry: a standard, a certification and CE marking. A standard (EN 13814, GB 8408, ASTM F2291) is a technical document. A certification is third-party verification, scoped to what was assessed. CE marking is a manufacturer’s declaration for the EU/EEA market, supported by a technical file.
Which one applies is decided by where the ride will be installed, not where it is built. The page below sets out the difference, the market-access route for each major destination, and what we do and do not claim.
Inspection at the end only tells you whether a defect was caught; it says nothing about whether the defect was created. Quality is held by seven documented control points, from drawing revision control and incoming material checks through welding, surface treatment, assembly and trial run, to pre-shipment and non-conformance closure.
Measurements are taken with 17 calibrated instruments, and every failed reading opens a written record that has to be closed before the item advances. The quality file travels with the ride.
Custom does not mean anything you want. It means finding the best ride mix inside five constraints: site, regulation, budget, throughput and maintenance capability. Four of those five have nothing to do with the ride model, which is why the model is chosen last, not first.
The page below gives the throughput calculation we run before recommending anything, the seven-step process with typical durations, the site data we need, and an honest list of what can and cannot be changed.
The order is not arbitrary. The destination decides the standard, the standard decides the load cases, the load cases decide the structure, the structure decides what has to be inspected, and the site and visitor profile decide what is worth building in the first place.
In practice that means the conversation starts with two questions — where is the ride going, and what does the site look like — long before a model is proposed. A supplier who quotes a model before asking those two questions has skipped the part that determines whether the project works.
With the site and the visitor profile, not the ride model. Send the plot dimensions, any height or clearance limit, the target daily visitors and the destination country; the ride mix follows from those. The custom design page lists exactly what is useful.
Usually all four, at different moments. Standards and compliance decides the design basis; structural analysis produces the calculation; quality assurance produces the records an inspector will ask for; custom design decides the layout and the mix.
Yes. The calculation report and the quality file are available for review by a third party appointed by you, and inspectors are welcome at the factory at any stage of production.
We provide the calculation report, drawings, material certificates, inspection records and the declaration of conformity. The approval itself is issued by the authority in your country, and the requirements differ by market — see which standard applies to your ride.
If you have a specific project in hand, send the site data and the destination country through the contact page and we will come back with the design basis and an indicative layout.
