The Future of Elevator Maintenance Starts Now

Predictive maintenance for control elements

SMART ELEVATOR

What is PredMa?
 

PredMa (short for Predictive Maintenance) is SCHAEFER’s smart system for real-time monitoring and predictive maintenance of elevator pushbuttons. It helps you plan service operations ahead of time — rather than reacting when it’s too late.

Why PredMa? 
Because unplanned breakdowns are costly — and stressful.
 

Imagine this…

An elevator goes out of service.
An elderly resident or wheelchair user is stranded — no access to their apartment, no way to leave the building. Stress and frustration build up.

A technician is dispatched — but can only diagnose the issue.
The right part is missing.

A second trip is needed.
More time. More cost. More downtime.

  • Initial inspection
  • Ordering the spare part
  • Second trip for replacement
  • Inactive elevator during the process
  • Double the cost — and unhappy tenants

With PredMa, this can all be avoided.
You’ll know in advance when a pushbutton is nearing end-of-life — and can replace it during scheduled maintenance.

How PredMa Works – The System at a Glance
 

The PredMa system is made up of four key components:

SCHAEFER IQ Pushbuttons

  • Patented intelligent pushbutton technology
  • Capture analog & digital sensor data
  • Redundant contact design for safety

DIM-IQ Modules

  • Aggregate and filter sensor data
  • Collect usage and call data from cabin and floors

Gateway (optional)

  • Enables cloud connectivity
  • Ideal where LAN or GSM/UMTS/LTE access is unavailable from other devices

SCHAEFER Cloud

  • Analyzes raw data into condition scores (traffic light model)
  • Push notifications upon critical values
  • API access for dashboards, IT systems, maintenance platforms
  • Auto-replenishment and planning support

Your Advantage: Maintenance with Foresight
 

Without PredMa:

  • Rigid inspection cycles
  • Blind spots between service intervals
  • High risk of unexpected breakdowns

With PredMa:

  • Early detection of wear and degradation
  • Use planned maintenance more efficiently
  • Up to 90% fewer emergency call-outs
  • Lower costs — better uptime — satisfied users

A Game Changer for Maintenance Companies
 

With skilled labor in short supply, efficiency is everything.

PredMa helps you deploy your technicians more effectively:

  • Technicians arrive prepared
  • Parts are already on board
  • No unnecessary inspection visits
  • More jobs completed with the same staff

Thanks to open API interfaces, SCHAEFER Cloud integrates seamlessly with your existing tools (ERP, field service, CRM, Lift-Link, etc.).
