The new market surveillance law – where have the elevators gone?
Gerhard Quanz
Kassel Regional Council
 
The EU's "New Legislative Framework," the so-called New Legislative Framework (NLF for short), set a lot of things in motion again in the middle of last year. In addition to the new Market Surveillance Act, the Product Safety Act still exists, and the European Market Surveillance Regulation and the Act on Installations Requiring Supervision are also new. Mr. Quanz will now attempt to shed light on the thicket of regulations and show us where the elevators have "gone."
Modern elevator drives part 2
Ludwig Semmler
Ziehl-Abegg SE
 
Modern elevator drives are synonymous with gearless drives. Investments have been made in this drive technology over the past 20 years. New drives are always directly connected to new suspension devices. These new suspension devices require both the drive manufacturer and the installation company to carefully review the type examination certificates as well as the applicable installation and operating instructions. If these instructions are correctly implemented, alternative suspension devices can be used successfully.

Smoke extraction and ventilation of elevators
Dipl.-Ing. Jan König
Ing4Lifts – Engineering office (VDI)
 
Higher demands on the energy efficiency of buildings and the resulting increasing airtightness of buildings mean that the issue of ventilation of elevator cars and smoke extraction from elevator shafts requires a new examination.
The specifications for elevator systems are partially specified in national regulations. Particular emphasis is placed on the ventilation of elevator cars and shafts. Potential CO2 concentrations are also considered in this context. Furthermore, smoke extraction from elevator systems is examined. The guideline offers assistance and solutions for the resulting issues.
This guideline closes a gap in previously missing specifications, especially for the ventilation of elevator systems. It provides all important information, instructions, and recommendations for the correct design of the necessary smoke extraction and ventilation of elevator shafts and cars in order to meet the protective objective of safe use of elevators. The guideline is aimed at manufacturers, planners, and operators of

Combating the shortage of skilled workers – compact training to become an elevator fitter
Dipl.-Ing. Volker Lenzner
VFA-Interlift eV
 
The shortage of skilled workers has been felt in all sectors of the economy for years, and in the elevator industry, the situation is even more pronounced: as a small industry, it receives little attention. VFA – interlift, representing the medium-sized elevator manufacturers, assembly companies, and component manufacturers, has therefore made it its mission for almost 15 years to offer continuing education for career changers. This presentation will report on current developments and future plans.

Legal requirements for building law lifts (lifts that are not used as work equipment)
Dipl.-Ing. Maynhard Schwarz
Fire Inspector
European-wide safety standards for elevators are implemented uniformly in Germany through the Product Safety Act and the Industrial Safety Ordinance. Elevator systems that serve neither commercial nor industrial purposes, and in whose danger zone no workers are employed, are not subject to these regulations. These purely "building law elevators" must be subject to requirements in the building law of the respective federal state. However, the scope of the state building code is often limited to the structural part of elevators. In some federal states, requirements for the mechanical part are not regulated at all. The authority responsible for monitoring is usually the building authority. There are very different requirements between commercial elevator systems and elevator systems subject to building law.
Different country regulations result in individual technical requirements!

Measurement and assessment of mechanical vibrations in elevator systems and their transmission
Roland Wendt
IDS Innomic
 
Demonstration of possibilities for ensuring compliance with limit values according to relevant standards and guidelines (VDI 2566, DIN 4109) with reference to the standards DIN 4150-2 and VDI 2038 by measuring mechanical vibrations of the individual components of the elevator and its coupling to building components.
Gearless elevator machines with alternative support means
Ludwig Semmler
Ziehl-Abegg
 
New suspension systems are being developed primarily to achieve advantages in the size and cost of the drives. This opens up new possibilities for the use of more compact drives.
Since the advent of machine-room-less elevators, many important development steps have hinged on suspension elements. Until now, these suspension elements in the medium-sized elevator industry have always been ropes. The term "suspension element" arose because belts were now being used instead of ropes.
One focus of developments over the past 20 years has been increasingly smaller drives, made possible by more "flexible" support elements. The second focus has been short shaft heads and shaft pits. These two topics are driving most innovations in our sector.

Miniaturized drives for drum elevators – More than just a niche
Prof. Dr. Wolfram Vogel
Expert for elevators, rope and lifting technology, Chamber of Commerce and Industry Stuttgart    
 
Dipl.-Ing. Klaus Sautter
The drum elevator has never lost its importance for vertical passenger and freight transport, particularly in the retrofitting of existing buildings and where high shaft utilization is required. For the first time, the standard limits for the drum-to-rope diameter ratio D/d≥40 for drum elevators were reduced to D/d=530 with great safety awareness in CA20 (SLC/TÜV Süd). The lower travel height due to the shorter rope length stored on the drum is now more than compensated for by a rope winding strategy new to the elevator.

Please use elevators in case of fire!
Dipl.-Ing. Maynhard Schwarz, Fire Inspector
Schwarz Engineering Office

Elevators are essential for barrier-free access. Today, they are generally unusable in the event of a fire. In the future, accessibility can no longer be planned as a one-way street in the event of a fire. Safety elevators, rescue elevators, and evacuation elevators are the new barrier-free escape routes in buildings. Being able to rescue oneself is the best fire protection for everyone. The two-tiered fire protection system for people in need of assistance is in blatant contradiction to the German constitution: No one may be discriminated against because of their disability.
The biggest barrier is the old mental principle: don't use elevators in the event of a fire. This approach needs to be rethought.
Which options and requirements will soon become universally applicable in the near future? What contribution does elevator technology have to make to this? Practical examples from practice.
Urbanization requires mobility – Effective transport concepts for passenger transport
Karl-Otto Schöllkopf
thyssenkrupp Elevators

Ecological, economic and infrastructural influences are accelerating the unmistakable trend towards urbanization not only from a global perspective, but will also lead to a concentration of living space in Europe, and not least in Germany, and thus to a realignment in the planning of major cities and important economic centers.
On the other hand, it is well known that further spatial expansion is subject to ecological and infrastructural limits. Therefore, the only option remaining is development into the third dimension. The height of buildings and facilities for living and working, education, leisure activities, and medical care will have to continue to grow. This will enable us to pave over less land and preserve important green spaces for local recreation and, above all, for local amenities for people around cities.
This trend is accompanied by the need to ensure the mobility of the people living in this concentration with new visionary approaches.
As new buildings are built ever higher, this has direct consequences for the vertical transport facilities in such buildings.
Innovation in elevator technology with multi-cabin solutions and the latest development of the first ropeless elevator system specifically for tall and very tall buildings, which is even capable of horizontal travel, can ensure that buildings can be planned much more efficiently with increased transport capacity and reduced floor space.
In addition, these new technologies make it possible to overcome previous system limitations implied by technological and external influences.
CONTI ® POLYROPE – An alternative support system is developing
Dipl.-Ing. FH Jan-Henning Quaß
ContiTech Drive Systems GmbH
 
For over 100 years, rope technology from elevator construction was virtually unmatched until the late 1990s, when the Otis Elevator Company, in collaboration with ContiTech Antriebssysteme GmbH, developed the new, space-saving flat belt technology for elevator construction. At the end of the 2000s, ContiTech took the next step, combining the advantages of rope and belt technology and developing the alternative POLYROPE suspension system. Since its release, the POLYROPE has been continuously developed to meet diverse customer requirements. The positive guidance of the POLYROPE on the drive pulley prevents run-off and frictional wear, unlike flat belt drives on crowned pulleys. Furthermore, the direct engagement of the ropes with the pulley improves the traction behavior of the system.
The introduction of the POLYROPE DP (with back profile) enables very narrow widths with the smallest pulley diameters thanks to its extended positive guidance on the deflection pulleys.
The increasing demands on fire protection (especially in the USA) were taken into account with the development of a fire-retardant version, the POLYROPE FR.
The next development step is the combination of the POLYROPE and the POLYROPE DP. The result will be a robust, positively guided system that will completely close the gap between rope and belt technology.

Vandalism – Standard EN81-1 “Class 2”
Klaus Trumpa
Schaefer GmbH

Increased vandalism is increasingly being observed in the field, which leads to increased downtime of systems and thus to increased maintenance at shorter intervals.
The presentation is based on the current version of DIN EN 81-71 "Protective measures against deliberate destruction" and examines the requirements of the various lift categories 0 – 2 with regard to the perceived situation in the field. The focus is on the direct interfaces between the lift and the lift user.

Structure-borne noise in the elevator
Ulrich Nees
Elevator systems + consulting
Structure-borne sound in elevator construction
The elevator as a transmitter of structure-borne sound is increasingly coming into focus when the sound pressure level is exceeded in rooms requiring protection. A large number
Sound events generated by an elevator system are transmitted through the shaft wall into the building. The term "sound" expresses the fact that the primary focus is on audible frequencies in the range of 16 Hz to 16 kHz. Elevator systems with a machine room rarely experience problems with structure-borne sound entering the building or rooms requiring protection.
Overview of topics: Introduction, measurement concept, rough surface structure-borne sound source, radiation of structure-borne sound by elevator components, structure-borne sound sources, measurements and measurement methods.
Type-tested elevator systems also as individual solutions
Volker Lenzner
LiftEquip GmbH Elevator Components
 
In order to be able to place type-tested elevator systems with free components on the market with little effort, LiftEquip has the systems tested with the required variants and supplements the type tests.
Type-tested elevator systems dominate large parts of the market due to their technically optimized solution and the associated economic advantages.
At LiftEquip, we utilize these advantages by removing the mechanical components from existing systems and offering our customers the opportunity to offer an open system with components such as a control system and other electrical components that are freely available on the market. 
This is the easiest way for the installation company to find a legally compliant solution for MRL systems on the market. Based on the electrical interface description and the documentation of the type-tested basic system, the customer can complete the elevator and then place it on the market through individual acceptance.
However, LiftEquip aims to offer its customers even better service to facilitate the use of these systems. To this end, we have the new system tested by TÜV Süd, based on the initial certification of the elevator system, including additional control systems and electrical components, as a complete system. The customer can then market the certified system with its own type-examination certificate.
I would like to use a few examples to report on the implementation and experiences in the market.
The Internet of Things and Services / Industry 4.0 | Significance for the elevator industry
Prof. Dr. Wolfram Vogel
 
The Internet of Things, Industry 4.0, is on everyone's lips. The Hannover Messe 2017 is once again highlighting this technological trend as groundbreaking. Policymakers are supporting, or rather, pushing all topics related to digitalization into society, industry, and the private sphere, including learning platforms in schools. This article provides an overview of the framework conditions for digitalization, describes the policymakers' intentions, and the opportunities for small and medium-sized enterprises (SMEs), which are so important to our society. Further interesting presentations from various speakers will follow at the Schwelm Symposium 2017, offering examples of current technological implementations.

3D sensors, a revolution for elevators
Christian Erik Thoeny
CEDES GmbH
 
The decades-old technology of light barriers and light curtains is being replaced by the disruptive future technology of TOF (time of flight). On the one hand, the three-dimensional sensors are becoming intelligent and can cover a completely different dimension of functionality. Systems or even multiple sensors can be replaced with a single sensor. On the other hand, installation efficiency increases by a quantum leap. For example, the sensors, which are several times smaller (half the size of a cigarette pack), can be integrated in the factory and no longer need to be assembled on site. An entire logistics component is eliminated, the advantage is enormous.

WEARwatcher – Results and findings of permanent wear monitoring
Martin Hauk, Henning GmbH & Co. KG
 
Last year, the concept of a condition monitoring system for elevators was presented at the Schwelm Symposium. It allows the implementation of a predictive maintenance strategy using just a few sensors. Unlike other industries, the elevator industry has so far used virtually no sensors to monitor the components of an elevator system.
Reducing the sensor technology to vibration, acceleration, and load sensors enables data analysis directly at the elevator system. Henning's many years of expertise in acceleration and load measurement systems have been incorporated directly into the evaluation algorithms. For example, this makes it possible to draw conclusions about the condition of the drive or gearbox by analyzing the vibration data.
The concept, presented in 2015, has now been implemented as the WEARwatcher product. This monitors the measured physical parameters of the elevator in real time. This enables the system to detect long-term trends as well as sudden changes. Comparison and diagnostic algorithms draw on a large amount of collected data and can thus provide maintenance recommendations.
This presentation shows the structure and design of the system and explains initial results.

The new elevator regulations 2016
Gerhard Quanz, Regional Council of Kassel
 
The Lifts Directive 95/16/EC has been significantly amended in several respects. Furthermore, it had to be aligned with Decision 768/2008/EC, which provides a uniform basis for the revision or recasting of sectoral legislation. This was achieved with Directive 2014/33/EU. Mr. Quanz from the Kassel Regional Council will report on the results of this at the national level for us in Germany in his presentation.
Innovative modernization concepts for elevator car doors!
Dipl. Ing. Thomas Lernet, Wittur GmbH
 
With this multifunctional driver system, the world's largest component manufacturer has achieved a quantum leap in elevator door modernization. The Vario-Coupler is suitable for combination with virtually all shaft doors with a locking mechanism integrated into the door mechanism. Thanks to its ingenious design, it can be used both as an expanding coupler and as a closing coupler. The position of the driver angles is just as variably adjustable as the functional dimension for locking and unlocking the shaft door. Naturally, the Vario-Coupler is equipped with a mechanical car door locking system in accordance with EN 81-20/50, whereby Wittur has remained true to its long-standing, proven design principle. As with all other car door locking systems, no additional attachments are required on the shaft doors.
Elevator use in case of fire
Dirk Preißl, State Capital of Düsseldorf
Fire brigade, rescue service and civil protection
Office 37/61 – preventive fire protection and hazard prevention
 
When using elevators in the event of a fire, in addition to the classic "fire service elevator" newly regulated in 2015, the "continued operation" of normal systems is increasingly being considered and used, as long as there is no danger to their operation. Whether the "evacuation elevator," currently being standardized, will truly provide a solution for barrier-free escape routes seems questionable.

Requirements for modern information systems for elevators
Jörg Hellmich, ELFIN GmbH
 
LED displays were previously used as an information system in elevators, sometimes supported by a voice announcement.
Today, a modern elevator is expected to have a TFT screen that provides voice announcements, displays elevator information, can also display multimedia data, and is easy to set up.
The following presentation will present the current possibilities of modern information systems and the requirements that arise from them.
Interactions between accelerations and acoustic effects
Ulrich Nees, Elevator Systems + Consulting
 
The cause of airborne and structure-borne noise in rooms requiring protection can be traced back to the interactions between the driving quality, the generated frequencies, and the sound insulation level of the shaft. Measurement technology can determine cause and effect, and appropriate measures can be implemented.
Problems with microswitches on lift brake release monitoring systems in the area of lift maintenance
Alexander Hutler, Christian Mayr GmbH & Co. KG
 
A release monitor prevents impermissible operating conditions on the elevator drive, such as driving against an engaged brake, and is therefore an indispensable element.
Mayr Antriebstechnik, as an alternative to the standard release monitoring with microswitches, also offers an innovative, contactless and therefore wear-free system with proximity sensor for elevator brakes
Modernization – why consulting is so important
Dipl.-Ing. Volker Lenzner, Technical Director,
LiftEquip GmbH Elevator Components
 
An existing elevator system is subject to various guidelines and standards that are subject to constant change.
These changes make it necessary to make different adjustments based on the safety assessment and the current plant usage.
the systems are to be brought into line with the state of the art.
The constant regulatory changes and discussions between the parties involved in the process are difficult for operators and/or employers to understand. In order to fulfill their obligations and commission appropriate modernizations, operators rely on information and sound advice.
In this lecture I will shed light on this area of tension.
A critical look at the new Industrial Safety Ordinance

The new technological revolution in elevator shaft ventilation.
Daniel Breitenbach, BlueKit Factory GmbH
 
Ventilation and smoke extraction in increasingly airtight buildings, even with closed elevator shafts!
 
Under the influence of the BetrSichVer 2015 and EN 81-20, it has become clear that elevator operators, in their responsibility as employers, can no longer be expected to assume theoretical smoke extraction or ventilation to the top elevator level without conducting a risk assessment when the elevator shaft is closed to the outside. Real-time tests, most recently conducted in Munich with the cooperation of DEKRA and RTL-Explosiv Weekend, have clearly shown that the lack of thermal energy in the elevator shaft can become a real threat to life under such conditions.

Lifecycle-oriented maintenance concept with “strategic components”
Prof. Henning Balck, F. Meermann, Balck and Partners / IPS
Institute for Project Methodology and System Services
Results of a research project and practical implementation at an airport.
In order to extend the service life of existing elevator systems, component replacements are necessary.
If the “strategic components” can be identified, this can be done with high efficiency –
while simultaneously improving system performance. The quality of the components also determines the life cycle costs of the elevators. These can be calculated according to VDI guidelines and made comparable using life cycle benchmarks based on operator data (developed in a research project at Fraport). The authors report on an approach that makes elevator products and services assessable in context. However, its success depends on the client and operator being able to make decisions together.
Innovative drive system for home elevators
Frank Lülfing, Dual Lift GmbH
 
Innovative – Economical – Unique: DualLift presents its new and innovative drive system for platform lifts compliant with EN81-41. Chains instead of ropes and two drive motors form the heart of the UpMax Home, ensuring maximum safety with the greatest possible comfort. Eliminating the need for a shaft head/pit and machine room, the UpMax Home is ideally suited for passenger transport in private homes and public buildings, making it a cost-effective alternative to a stairlift.
VDMA calculation tool for A3 braking distance determination
Dr. Holger König, Emmerson Industrial
 
Since Amendment 3 to EN81-1, elevators are required to have a protective device to prevent unintentional movement of the car when the car door is open. Proving compliance with these limits is a challenging issue, as the assumed failure scenario of acceleration at maximum torque is risky and practically impossible to verify. Companies that assemble the protective device from commercially available components, in particular, require a practical verification procedure with a free choice of monitoring and braking devices. The Components Committee of the VDMA (German Engineering Federation) for Elevators and Escalators has formed a working group for this purpose, and the author reports on its results. EN81-20 and EN81-50 introduce further innovations, which will also be discussed in this presentation.
Operator responsibility and legal significance of recognized rules of technology
Dipl.-Phys. Thomas Wollstein, VDI Association of German Engineers
 
The operator of a property or facility acts as a guarantor to its users. However, the requirements this entails and how they can legally delegate responsibility are often unknown. The situation is complicated by so-called vague legal terms such as "state of the art," "recognized rules of technology," and the like. This presentation is a valiant attempt by a non-lawyer to make navigating this jungle easier by explaining the fundamental concepts.

APS – Absolute Positioning System from CEDES
Klaus-Michael Ziehm, Cedes GmbH Electronic Devices 
 
APS is an innovative, completely contactless and robust shaft information system. As a SIL 3-based and TÜV-certified safety system, it opens up new possibilities in elevator control design. With an appropriate elevator control system design, significant cost savings can be achieved by eliminating safety components compared to conventional shaft information systems currently available on the market. Furthermore, simple and flexible installation reduces installation and commissioning times. Changes in the shaft image that occur over time due to building compression can be automatically compensated for by the system.

Consideration of the overall economic and normative situation of the elevator system subject to monitoring
Actual energy consumption of elevators
Ludwig Semmler, Ziehl-Abegg AG

The energy efficiency of elevator systems and components has become an increasingly important focus for elevator companies and operators in recent years. VDI 4707 makes it possible to determine the actual energy consumption of elevator systems. The VDI 4707 label is often used in advertising.
“My” elevator has energy class A. This statement can be read alongside many relative numbers.
How should such statements be evaluated? How much money can one actually save? How sensible is energy recovery?

The all-rounder SL6 becomes a directly connected partner to the control system. All advantages at no extra cost that you can offer your customers. Displays and voice announcements work with the CANopen bus. The active elevator attendant LiftSafe monitors the entire system – added value for everyone.
Simple and economical wiring of floor control panels with LIN
Holger Klaus, Hans and Jos. Kronenberg GmbH

The wiring of elevator floor control panels varies greatly depending on the requirements and circumstances. Designs range from a single push button per floor and just two stops to complex group control systems with information displays, acoustic signaling, and access and priority control at each shaft door. Finding an optimal wiring standard in this area is a challenge. Common bus systems are usually over-suited for the simple signals of floor control panels. In addition, space is sometimes limited, as bus nodes and control elements must also fit into narrow door frames and wall boxes. A solution based on the Local Interconnect Network (LIN) is presented. The LIN bus is a proven serial single-wire bus used in the automotive sector. The UTLIN push button even combines the LIN bus node, call button, and travel indicator into a single compact module. The LIN bus solution is complemented by practical shaft wiring.
