Rexroth Updates the Eiffel Tower

Enjoy foreign films? Here’s one that demonstrates once again that Rexroth is involved in motion control in all the coolest places.

The western pillar of the Eiffel Tower needed an update for its elevator. It was essential that the new technology fit the original and remain true to the original intent, but it was also essential to reduce energy usage and meet modern safety standards. Using a melange of original construction concept and modern engineering, Rexroth was able to recreate the elevator with a 25% reduction in energy use.

Gustave Eiffel built the tower in 1889, and it was the tallest building in the world for four decades. He wanted as many people as possible to be able to go up the tower and see the amazing view of Paris. The challenge? the elevators don’t go straight up and down. They have to adapt to the shape of the tower.

An indirect hydraulic mechanism was the solution, and it still is. Rexroth is the master of both hydraulic and electric motion control. The engineers working on the Eiffel Tower had the advantage over the original engineers of being able to use Rexroth’s SIMSTER simulation system. This allowed them to test a variety of concepts before settling on one option.

The modern engineering is invisible. The pumps are underground. The cabins of the elevator are unchanged. The pump room itself is functionally state of the art, but elements of the original pump room remain to keep the engineering room visually true to the original.

We specialize in Rexroth electric industrial motion control, from legacy parts of the 20th century to the newest IndraDrive components. We offer phone support, field support, and factory repair and reman. With every job we do, we strive to maintain the same integrity that makes Rexroth the top choice for motion control in the coolest places in the world.
