From means of transport to digital system
The elevator has fundamentally changed in recent years. What was once primarily a mechanical-electrical means of transport is now a networked, data-generating, and partially self-optimizing system.
Part one provides a view of the details and intentions of this opportunity for change and improvement in periodic testing of traction elevators to ensure safe operation.
Intelligent load measurement for elevators – much more than just overload control
Thanks to intelligent sensors and integrated computing units with quite high performance, overload measurement is becoming an important tool for efficiency assessment and condition-based maintenance.
Socializing and specialist lectures atSchwelm Symposium
From May 19 to 20, 2025, representatives from the elevator industry met for the 21st time at the Schwelm Symposium. The approximately 120 participants were able to listen to 18 specialist presentations, visit the trade exhibition, and engage in discussions at the pre-event event and during the breaks. The date and a new venue for 2026 have already been confirmed.
Cybersecurity: Draft standards with massive consequences
The draft of Part 20 of the ISO 8102 series on cybersecurity for elevators and escalators (Electrical requirements for lifts, escalators and moving walks) was recently published. Tim Ebeling, Managing Director of the elevator measuring device manufacturer Henning, is the representative of VFA-Interlift on the "Digitalization and Cyber Security" committee of the European Lift Association (ELA). We asked him for his assessment of the draft.
Elevator 4.0 – Opportunity and threat for small and medium-sized businesses
The Internet of Things (IoT) isn't stopping at elevators either. The first predictive maintenance solutions are establishing themselves on the market, and numerous new entrants in the IoT industry are seeing this as a profitable field of activity. Therefore, service companies must now position themselves correctly.
In recent years, problems with excessive rope wear have been increasingly observed in elevators. The suspension elements sometimes have to be replaced after just a few years or even months. The causes are varied. In the following, some of the causes will be examined in more detail and measures will be presented that reduce wear and thus delay the discard date.
Innovative maintenance concepts and visions using elevators as an example (interview with T. Ebeling)
On behalf of the Federal Ministry for Economic Affairs
An interview by the Mittelstand 4.0 agency Processes with Tim Ebeling (Managing Director of Henning GmbH & Co. KG, elevator component manufacturer from Schwelm)
The digital transformation is already in full swing – especially in small and medium-sized businesses. This shows that reliable maintenance and life-extended and predictive maintenance measures based on new technologies are becoming key factors.

Ride quality measurements and monitoring of escalators and moving walks
Correct measurement instead of subjective feeling is the starting point for a correct diagnosis. This sentence was used in 2005 to ISO 18 was introduced for measuring the ride quality of elevators. The latest revision of this standard has now published Part 738, which deals with the objective ride quality measurement of escalators and moving walks. Vibration data from the load carriers and handrails are collected and evaluated together with sound pressure levels to provide a quantifiable representation of human perception during escalator use.
The donut load sensors were developed to accommodate the ever-shrinking installation space in elevators. The sensor is mounted in the rope suspension (dead center) together with the elastomer spring buffers or compression springs, making them suitable even for very small shaft heads. It doesn't matter whether the sensors are conventional steel ropes or belts.
Risk potential of safety gear – tests with test weights are not sufficiently conclusive!
The almost worldwide common practice of using the safety gear of elevators There is a clear justification for testing the weights used when placing the product on the market: During these tests, all components are subjected to a mechanical Stress tests are carried out to detect assembly errors and structural deficiencies. However, this test can determine the effectiveness of the safety gear in the worst case – the emergency stop from free fall with full load – only very limited or not prove. The same applies to any recurring Tests at the required time intervals. This thesis cannot be not only can it be demonstrated with numerous practical examples, but it is also easily understandable from a physical perspective.
