Ferris Wheel: History, Design, and Manufacturing Insights

Background

A ferris wheel is an amusement park ride featuring a large vertical wheel with evenly spaced passenger stations along its circumference. As the wheel rotates around a horizontal axle, riders experience gradual lift and descent. When a car reaches ground level, passengers disembark, new riders board, and the wheel continues its motion until all seats are occupied, after which it completes multiple revolutions.

History

The concept traces back to ancient irrigation wheels, repurposed for entertainment as early as 200 B.C. In 1620, traveler Peter Mundy described a “pleasure wheel” in Turkey, and by 1728, English hand‑turned wheels were known as “ups‑and‑downs.”

In the United States, Antonio Maguino erected one of the first amusement wheels in 1848 in Walton Spring, Georgia, sparking a wave of commercial production. Charles W.P. Dare of Brooklyn built wooden wheels of 20‑ and 30‑ft diameters in 1870, and the Conderman Brothers produced a 35‑ft metal wheel in the 1880s.

The pinnacle came in 1893 when engineer George W. Gale Ferris constructed a 250‑ft (76.2 m) wheel for the Chicago World’s Columbian Exposition. Modeled after a bicycle rim, the wheel measured 250 ft in diameter, housed 36 enclosed cars, and carried 1,440 passengers. Its 46.5‑ton structure drew over 1.4 million paying visitors in 19 weeks, cementing Ferris’s legacy.

American inventor William E. Sullivan, inspired by the Columbian wheel, designed a 45‑ft (13.7 m) transportable wheel in 1900, leading to the Eli Bridge Company in 1906. Today, most U.S. carnival ferris wheels are produced by this company.

Raw Materials

Steel dominates construction, forming chassis, towers, spokes, and cross‑members. Structural shapes include square tubing, round tubing, angles, channels, and wide‑flanged beams. Aluminum diamond tread plate lines walkways and the operator’s platform.

Seats and drive rims are aluminum, chosen for its resistance to abrasion from the rubber drive wheels. Seats use self‑skinning polyurethane foam for a smooth exterior and compressible interior. Nylon, phenolic plastic, copper, and carbon are employed in bushings, electrical components, and lighting systems.

Key components such as axles, brakes, tires, trailer wheels, electric motors, and lighting assemblies are often sourced from specialized suppliers.

Design

Transportable ferris wheels must meet highway dimensional limits: typically 8.5 ft (2.6 m) width, 13.5 ft (4.1 m) height, and 55 ft (16.8 m) length. The wheel folds to these dimensions for road travel while expanding to full size at the destination.

Safety engineering includes load calculations for horizontal and vertical forces, interlocks preventing rotation during loading, and operator safeguards to avoid accidental activation.

The Manufacturing Process

The following steps outline the construction of a typical 60‑ft (18.3 m) transportable ferris wheel with 48 riders.

Building the Chassis

• Cut chassis components to length with a saw or torch, weld them, and attach vertical support posts to the forward section.
• Sandblast the chassis to remove weld spatter and scale.
• Apply a rust‑inhibiting primer, then finish coats of paint.

Installing the Towers

• Mount two wheel‑support towers on the chassis, hinging at the lower ends and resting on the support posts.
• Install hydraulic cylinders midway along each tower to raise them into operation.
• Attach lateral support arms for side‑to‑side stability, locking them with pins when fully extended.
• Route hydraulic and electrical lines, and install the operator control station.

Installing the Spokes

• Lay sixteen pairs of spokes on the factory floor, add cross‑members and drive‑rim sections, and stack them with V‑shaped lighting booms.
• Lift the stack onto the trailer, attach the top pair to the hubs, and unfold the spokes into vertical position.
• Secure spokes to hubs, bolt drive‑rim sections, and connect electrical cables to lighting booms.
• Install mechanical support cables along the outer circumference and X‑pattern cables between spokes for stability.

Finishing the Wheel

• Fabricate, paint, and install entrance/exit stairs, walkways, safety fences, and trim.
• Mount seats—four fixed to the wheel, the remainder on the trailer and pinned after erection.

Safety Considerations

Safety is paramount. Regulations differ by jurisdiction, and the American Society for Testing and Materials (ASTM) is developing a comprehensive standard covering design, testing, manufacturing, and operation of all amusement rides. Manufacturers and operators actively participate in this process.

The Future

Ferris wheels, a staple of leisure for centuries, will likely continue to enchant riders. While high‑thrill attractions dominate parks, the gentle elevation and panoramic views offered by ferris wheels remain uniquely appealing.
