LiftBoy®
Barrier-free lift operation via smartphone
Contactless. Hygienic. Accessible to all.
SMART ELEVATOR
With LiftBoy®, you can control elevators hygienically and intuitively via an app—particularly helpful for people with mobility or visual impairments. Can be retrofitted to almost any elevator.
Who is LiftBoy relevant for?
LiftBoy is aimed at:
- Elevator manufacturers and modernizers looking for retrofittable, control-independent systems
- Building operators & property managers who want to increase comfort and accessibility
- Representatives of public authorities who need to implement legal accessibility requirements
- Disability associations & interest groups looking for concrete solutions for greater participation
What is LiftBoy?
LiftBoy is a system for barrier-free and contactless elevator operation via smartphone. It consists of:
- a user-friendly app, optimized for screen readers, voice control, and smartwatches
- and Bluetooth modules (LiftBoy GIM) that are connected directly to the buttons in the elevator—without interfering with the elevator control system
This allows the elevator to be conveniently operated via the app—without physical buttons and without an internet connection.
