Hydraulic Renovation for Eiffel Tower
The Eiffel Tower was originally constructed with five hydraulic systems for each of the elevators installed. This construction took place more than 100 years ago and it is said that the principal mechanics are still set in place.
In order to conform to the current century, the elevators were upgraded. Replacement parts and upgrades were performed with the intention of being more energy efficient, or modern.
Also, to keep the thousands of daily passengers moving up and down the tower, mechanics working on the project thought the hydraulics could be updated and improved.
The remodel was completed by one of the most trusted manufacturers in the hydraulic industries, Bosch Rexroth.
According to Hydraulic and Pneumatic News, the new system is designed to complement the original design configuration with “two lift cylinders and three pressure-storage cylinders (accumulators). However, unlike the original system, valves do not control the ascent and descent motions.”
There is now a controlled variable in speed both for ascent and descent.
What that means is that 25% more energy is conserved when carrying up to 1,000 passengers per hour to the top.
