The Eiffel Tower, an iconic symbol of Paris, France, receives millions of visitors every year. One of the main attractions of the tower is its hydraulic lifts, which transport visitors to the different levels of the tower. The speed of these lifts is a fascinating aspect of the Eiffel Tower, and this article will explore the technical aspects of the hydraulic lifts and how they operate.
The Hydraulic Lifts of the Eiffel Tower
The hydraulic lifts of the Eiffel Tower were installed during the tower’s construction in 1889. These lifts were a major feat of engineering at the time, as they were among the first hydraulic lifts to be constructed. The hydraulic lifts were designed by French engineer Edoux Contamin, who was also responsible for the tower’s structural design.
Historical Overview of the Eiffel Tower
The Eiffel Tower was built as the entrance arch to the 1889 World’s Fair, which celebrated the 100th anniversary of the French Revolution. The tower was named after its designer, Gustave Eiffel, a French engineer who also designed the Statue of Liberty’s metal skeleton. The tower’s construction took two years and two months and involved the work of around 300 steel workers.
Evolution of the Hydraulic Lifts
The hydraulic lifts of the Eiffel Tower have undergone several changes since their installation in 1889. In 1899, the original hydraulic system was replaced by a new system, which increased the lifts’ speed and capacity. In 1983, the original hydraulic lifts were replaced by new lifts, which were faster and more efficient.
Technical Features of the Hydraulic Lifts
The hydraulic lifts of the Eiffel Tower are powered by a hydraulic system, which uses water pressure to lift the lifts up and down the tower. The hydraulic system consists of a pump, a hydraulic cylinder, and a tank. The tank stores the hydraulic fluid, which is pumped into the cylinder to lift the lifts.
The Role of the Hydraulic System
The hydraulic system plays a crucial role in the operation of the Eiffel Tower’s lifts. The system provides the necessary force to lift the lifts up and down the tower. The hydraulic system also controls the speed of the lifts, ensuring that they move smoothly and safely.
How Fast Do the Hydraulic Lifts Move?
The hydraulic lifts of the Eiffel Tower move at a speed of about 2 meters per second. This equates to about 7.2 kilometers per hour or 4.5 miles per hour. The lifts take about 1 minute and 30 seconds to reach the top of the tower from the ground floor.
Speed Comparison: Hydraulic Lifts vs. Stairs
The hydraulic lifts of the Eiffel Tower are much faster than the stairs, which would take hours to climb to the top. Climbing the stairs of the Eiffel Tower is not recommended for visitors, as it is a strenuous activity that can be dangerous.
Safety Measures in Place
The Eiffel Tower’s hydraulic lifts are equipped with several safety features. The lifts have an automatic braking system, which stops the lifts in case of an emergency. The lifts are also equipped with a backup power system, which ensures that they can continue to operate in case of a power outage.
Maintenance and Upgrades
The hydraulic lifts of the Eiffel Tower require regular maintenance to ensure their safe operation. The lifts are inspected and serviced on a regular basis by a team of technicians. The lifts are also upgraded from time to time to improve their speed and efficiency.
Conclusion
The hydraulic lifts of the Eiffel Tower are an important part of its history and architecture. The lifts are a testament to the ingenuity and creativity of French engineers of the time. Today, the lifts continue to transport millions of visitors to the top of the tower every year, providing a unique and unforgettable experience.
