Innovation in difficult times -

with unexpected actuality

In times of the current corona pandemic, we perceive our environment more consciously and more and more potential dangers to our health become apparent. This increased awareness will continue to accompany us after Corona. According to a recent publication in the Journal of Hospital Infection, corona viruses on metal and glass surfaces, for example, can survive for up to 9 days. This also applies to buttons in elevators. A single highly frequented elevator, e.g. in hospitals, department stores, train stations, etc., can transport several 10,000 people during these 9 days. According to the study, other pathogens even survive for more than 28 days.

More hygienic operation of lifts

One of our innovations is currently experiencing undreamt-of topicality. LiftBoy - a solution for elevator operation via smartphone that was actually developed to improve comfort and promote accessibility. The elevator call and floor selection can be made manually via the app or fully automatically. The smartphone can remain in your pocket. The elevator automatically detects when a user with an installed app approaches the elevator, calls the elevator and automatically selects the destination floor. The system consists of hardware components that are integrated into the landing operating and car operating panels and a corresponding app (for iOS and Android). The solution can be used in new installations as well as in modernization projects. Due to its control independence, the LiftBoy can be easily retrofitted and thus create the possibility of contactless elevator operation in many places.

Improve accessibility

In addition to the advantage of more hygienic operation, the system also benefits handicapped users. Many lifts are not yet equipped with an additional handrail or desk panel so that wheelchair users can reach all buttons without assistance. Visually impaired people also often find it difficult to operate elevators. They also benefit from operation via smartphone and can regain a little more independence in everyday life.

LiftBoy - App-based elevator call & floor selection

The LiftBoy app allows elevators to be controlled via the smartphone. For lift systems that are equipped or upgraded with the LiftBoy GIM node (car operating panel or landing operating panel), lift calls and floor selections can be made conveniently via the smartphone.

In addition to the manual mode, an automatic mode is also available, which can be adapted to personal habits by means of many setting options. In residential or office buildings, for example, regularly used floors and lifts can be preset so that you are automatically called to the detected floor or automatically select the preset floor when you enter the elevator. This not only shortens unpleasant waiting times, but also improves barrier-free use.
