Yes, you read that right. I assert we will need to miniaturize our products’ burden on buildings while having bigger experiences and faster delivery times which requires stronger materials. 

Remember Ironman’s super-cool digital screens inside his ocean-side lair? Well today, thyssenkrupp announced that our service technicians will use HoloLens technology in its elevator service operations worldwide.

There is no getting around it. If your building is two stories or hundreds of feet, you are going to need an elevator. You have to meet the American Disabilities Act codes but what you don’t need is a complicated elevator system to travel just a few feet.

The term “smart city” can be open to interpretation. Here are a few prerequisites established a few years ago.  A smart city uses technologies to be more intelligent and efficient when using resources.

thyssenkrupp is currently putting the finishing touches on the installation of 30 elevators and 2 escalators that will serve 52 floors at River Point, a new office tower located on a prime piece of property overlooking the Chicago River.

Have you ever noticed that your hydraulic elevator is sluggish in cold weather? The problem is likely because the hydraulic oil that operates the elevator needs to be kept warm, ideally at a temperature range between 100 -130 degrees Fahrenheit. When the elevator doesn’t run, the hydraulic oil cools down and becomes thick and gummy which can cause rough starts, bumpy rides, leveling problems and put unnecessary  strain on the equipment.     

Hydraulic elevators are raised by forcing pressurized fluid through a valve into a steel cylinder located above or below ground. The pressure forces a piston to rise, lifting the elevator platform and car. The outside temperature or machine room temperature is directly related to hydraulic oil temperature. Changes in oil viscosity are more apparent when the outdoor temperature or machine room is cold. When not in use, the oil within the tank will try to reach equilibrium between its temperature and that of its surrounding environment.

Tank heaters are installed inside the oil tanks of hydraulic elevators to heat and thin the oil to prevent rough starts and variations in smooth operation. Tank heaters keep the hydraulic oil in your elevator at a consistently warm temperature with a built-in, fixed thermostat. This thermostat controls the oil temperature so that it never falls below its optimal functioning level of at or around 100 degrees. If the thermostat of the oil dips down below 90 degrees, the thermostat closes and the tank heater begins to operate. The tank heater will continue heating the oil until it gets to 110 degrees. At 110 degrees, the thermostat will open and the tank heater will stop heating the oil.

Ambient temperatures are just one of the building conditions that can affect elevator performance. To see a list of other factors, see a list from the National Elevator Industry, Inc.
