The structural and dynamic engineering is based on German safety standard DIN 4112 for temporary structures. Amongst others, Finite Element Method and wind simulation tests are used to precisely predict the wheel's behavior. Wind and weight calculations are carried out according to DIN 1055 and DIN 4112 and upgraded to local conditions if required.

The giant wheel is completely designed, calculated and manufactured according to German DIN standards and each wheel is individually surveyed and approved component by component and as an entire structure by the German TÜV organization. Upon request, standards can be adapted to meet with local standards.

The wheel structure is executed as a fixed wheel, type SV, and comes with foundation plates, used for a foundation that will hold the wheel. The mobile wheel, type SP, carries its own fully integrated floor and ballast system. The wheel is delivered in containers and set up with the use of one or more cranes, depending the type. Buildup takes between one and two weeks under normal conditions. The fixed version will need additional time to construct wheel deck attributes like loading ramp and ticketing booths. An SP type mobile wheel is delivered as complete as possible with features such as ticket boxes, entrance and will be ready for operation.

 

Supporting masts

The base of the construction consists of eight (8) supporting masts, manufactured in welded round steel tubing. The mobile wheel will be supplied with its own integral floor plan with foundation and water ballast tanks. The masts form a double A-frame which will cradle the main axle. The main axle and masts are connected by fast and sure double secured pin connections. The main axle surround is fitted with a number of slip rings controlling the power supply to the individual gondolas and lighting system. The outer axle is fitted with a slip ring to ensure good lightning conductivity to the ground.


Coating system

Masts, spokes, ring sections and main axle are sand blasted SA 2.5, after which an epoxy primer, epoxy intermediate and polyurethane topcoat follow. The coating will carry a warranty certificate from the paint supplier. The Gondolas will have an extra hard topcoat, specially designed for extreme weather conditions. The expected frequency of painting is every 5 to 10 years provided frequent maintenance is carried out.
