Ever wished that elevator would travel just that little bit faster so you wouldn’t be late for your meeting? Or maybe the sales in the store on the third level were running out and you needed the elevator to hurry up? Well Mitsubishi have just announced elevators that will be capable of traveling faster than 1,000 metres per minute, or 60 kilometres per hour.

The new technology announced on Friday will also come with “enhanced efficiency, comfort and safety.”

According to the press release from Mitsubishi Electric, these new technologies will be incorporated into the world’s fastest elevators including those developed for the 632-metre high Shanhai Tower currently under construction in Shanhai, China.

Mitsubishi provided a full list of advancements which I’ll paste in below, but one really has to ask the serious question: how fast is too fast for an elevator to travel? Because, personally speaking, I can see myself being more than happy to take the stairs if these death-boxes elevators get too fast.

 

1. Drive and Controllability

- The traction motor incorporates a permanent magnetic motor for energy-efficient, low-noise, low-vibration operation.
- A single motor has two grouped three-phase winding coils and parallel drive systems controlled by separate control panels. Each motor has a built-in converter to regenerate electricity, lowering power consumption by more than 30 percent.
- Brakes composed of two units with a hydraulic driven clamp-type disk brake achieve stable braking.
2. Safety

- Safety gears, which activate the brakes by grasping the guide rails in emergencies if cables become transected, comprise two stages to manage increased kinetic energy due to ultra-high speeds.
- Fine ceramic is used for the safety gear shoe to realize high resistance to heat, abrasion and shock. Braking is extra-stable even if high frictional heat is generated when the safety gear is activated.
- The hydraulic oil buffer (shock absorber) at the bottom of the elevator shaft has an advanced plunger comprising three stages for exceptional shock absorption within a shortened frame.
- Newly developed governor monitors elevator speed stably even with heavy loads placed by ropes traveling at high speeds over long distances.
3. Super high-rise cable mechanics

- A steel core with a wider diameter provides high intensity, allowing traveling cables to be lightened by using lightweight sheath material and operated by a highly efficient electric power carrier system.
- Mitsubishi Electric’s new “sfleX-rope” comprising bundles of high-intensity steel wire strands, each covered with plastic, offers higher intensity than conventional rope for safe operation despite the greater weight of longer ropes. Each wire has a higher density and wider cross-sectional area than conventional rope, which helps to reduce rope stretching caused when passengers step onto the elevator.
4. Ride comfort

- A new active roller guide, which reduces vibration from the guide rails and wind, enhances passenger comfort even at ultra-high speeds.
- The inside of the car is extra-quiet thanks to a streamlined aerodynamic car cover and a high sound insulation cage.
- Air pressure control helps to minimize rapid changes in atmospheric pressure for reduced ear discomfort.
