Elevators were installed around 1880. At the time, they used a gate for an inner door. Over time, they began installing automated doors on both sides. The modern electric traction elevator was invented in the early 1900s, and it remains the industry standard to this day. As elevator history evolved and expanded to include more advanced safety and efficiency features, vertical transportation was made safer and more convenient than ever before. Today’s elevators are safer than both escalators and stairs, making elevator transportation the safest way to travel to your destination.
