Hauteur de la tour de chute: Ce que vous pouvez construire sur votre site

Every vertical amusement ride project reaches the same early question: quoi hauteur de la tour de chute will the site support? The answer is not simply the tallest model that fits inside the property boundary. Height affects planning approval, structural loads, conception des fondations, exposition au vent, levage, fret, inspection and the emergency plan.

DINIS builds three rotating tower models and the 63 je suis en chute libre. Their marketed names and engineering heights are not always identical. Le 15 m tower has a 16.9 m structure et un 12.5 m hauteur de travail; le 35 m model has a 32.4 m structure et un 28.5 m hauteur de travail. Both figures must appear in the project discussion because the planning authority, structural engineer and operator use different measurements.

Hauteur de la tour de chute: structure height vs operating height

Structure height is the physical equipment dimension used for site planning and approval. Operating height is the highest position used by the ride cycle. Do not use the model number as either measurement.

The working height should be confirmed on the approved general arrangement drawing. Ask whether the authority measures the structure, lightning rod, antenna or any rooftop beacon, and confirm the exact reference height used in the permit application.

Why the model name and engineering height differ

Model names are commercial labels. Le 15 m, 25 m, 35 m et 63 m names help buyers compare the range, but the technical package contains the actual structure and operating figures. Le 35 m model is a clear example: it is marketed as 35 m, has a 32.4 m equipment height and reaches 28.5 m during operation.

Use the engineering drawing for foundations, clearances, crane planning and approvals. Using the model label without checking the detail can either overstate the site requirement or, more dangerously, understate the foundation and lifting scope.

Start with the maximum permitted height

Before choosing a ride, obtain the maximum structure height allowed on the exact plot. The limit may come from zoning, airport or flight-path restrictions, heritage sightlines, local amusement-device rules, building height limits or the property owner’s requirements.

If the approved limit is 18 m, le 15 m model may fit and the 25 m model does not. Si la limite est 30 m, le 35 m model is outside the structure limit even though its commercial name is often treated as the same number. Establish the permitted height in writing before ordering the foundation design.

Height approval: the five practical stages

1. Pre-application review

   Envoyer l'intrigue, permitted use, maximum height, nearby buildings, roads, flight paths and any local amusement-device requirements to the relevant authorities.

2. Model and site-envelope selection

   Match the structure and operating heights to the site, then add the queue, entry and exit, maintenance access, emergency route and lifting area.

3. Technical documentation

   Prepare the general arrangement, foundation loads, anchor positions, electrical data, manuals and inspection documents required for local review.

4. Foundation and installation approval

   The local structural engineer designs the foundation from the final loads. Civil work, position de la grue, power connection and assembly are then completed against approved drawings.

5. Testing and operating handover

   Complete no-load and loaded tests, verify emergency functions and hand over inspection records, manuals, spare list and operator training before the ride opens.

Requirements vary by country and city. The list above is a project checklist, not a substitute for the local approval process or the authority’s written requirements.

What changes between 15 m et 63 m

Foundation and structural loads

The foundation must be designed for the selected model, soil conditions, groundwater, local wind requirements and the manufacturer’s anchor layout. UN 63 m free fall has a completely different structural and geotechnical package from a 15 m tour tournante; a generic concrete slab is not a foundation design.

Wind exposure and operating rules

Height and open site exposure increase the importance of wind monitoring, shutdown criteria, storm preparation and post-storm inspection. Use the operating limits in the approved manual and the site-specific risk assessment rather than assuming one wind limit applies to every country or installation.

Lightning and electrical protection

Confirm lightning protection, earthing and the location of the control system. The installed power range runs from 40 kW on the 15 m tower to 520 kW on the 63 je suis en chute libre, so the transformer, cable route, switchgear and control room must follow the selected model.

Fret, lifting and installation

Taller structures are split into more transportable sections. Le 15 m model is listed with two 40HQ containers at about 11.5 t; le 35 m model is listed with three 40HQ containers at about 22.6 t. Confirm the final packing list and lifting plan with the quotation because cabin, thème, enclosure and destination can change logistics.

Emergency planning and maintenance access

Define the rescue route, operator position, access for maintenance and emergency services, and the procedure for a stopped ride at height. These items belong in the site drawing before construction starts, not in a conversation after the equipment arrives.

Indoor drop tower clearance

The compact tower can be considered for a covered site, but the finished building clear height must exceed the full structure height and leave room for installation, entretien, éclairage, roof structure and any protection system. Do not compare the 12.5 m operating height with the ceiling height and assume the 16.9 m structure will fit.

• Finished floor-to-lowest-obstruction height after beams, ducts, lighting and sprinklers.
• Floor loading and the route used to move the heaviest sections into the building.
• Opening sizes, crane or forklift access and temporary protection for the finished floor.
• Queue, entry, exit, operator position and emergency evacuation away from the ride envelope.
• Electrical room, isolator, cable route and protection against water or accidental contact.

Outdoor drop tower site envelope

The equipment footprint is only one part of the plot. The approved layout should also show the safety boundary, clôture, file d'attente, portes, operator station, maintenance access, foundation projection, drainage, crane position and delivery route.

For roadside or city-centre sites, add sightlines from neighbouring properties, noise, lighting spill, traffic and emergency access. For park sites, coordinate the height with the master plan, surrounding attractions, landscaping and any future expansion.

Documents to prepare before the order

Can a drop tower be extended later?

Extending the height of an installed tower is not a normal field modification. The structure, hydraulic system, conduire, fondation, manufacturer’s approved design, inspection file and planning approval may all change. Moving an existing ride to another site can be evaluated, but a taller new ride should normally be planned and purchased as a complete model.
