Condition monitoring is a crucial task for electromechanical system reliability and quality enhancement, which allows early electrical and mechanical faults detection, leading to a predictive maintenance. The aim of this paper is to analyze the feasibility of a virtual sensing approach to perform a health diagnosis in the context of elevators. The virtual sensing approach will make use of an electromechanical model of the elevator and some measurements available in order to obtain several other physics (virtual sensors). A lab-scale elevator test bench will be used to test the methodology, obtaining several indicators and analyzing its evolution in time.
HILA – A NEW COMPACT MRL HYDRAULIC ELEVATOR FOR HIGH-RISE
Kjell Johansson, Magnus Landberg, Pär Lindman, Sweden | firstname.lastname@example.org
In general, hydraulic elevators, limited to low speed, are only suitable for low-rise buildings. The Hydraulic Infinite Linear Actuator (HILA) is a new kind of hydraulic cylinder technology that has the potential to eliminate these limitations. The technology allows for very long strokes and high speeds, which opens up for hydraulic elevators in high-rise buildings. The HILA cylinder is very compact and resource efficient. It allows 10 times higher hydraulic pressure than today’s hydraulic elevators. In this paper the focus is on Life Cycle Assessment. HILA technology turns out to be superior to conventional electric and hydraulic elevators but also to electric linear motor driven elevators.
STATIC, CYCLIC, AND ACOUSTIC EXPERIMENTAL INVESTIGATIONS OF JORDAHL ACOUSTIC ISOLATION
Florian Julier, Germany | email@example.com
The resulting operational noise of elevators can be an acoustical impairment to the usability of rooms in the vicinity of the elevator shaft. Currently the best technological efforts to acoustically insulate elevator components are not able to prevent significant transmission of noise and vibration to the elevator shaft walls. The JORDAHL Acoustic Isolation product is designed to decouple this transmission chain, and so prevent the vibro-acoustic transmissions reaching the elevator wall and building structure. Static, cyclic, and acoustic experimental investigations have been carried on different prototypes of JORDAHL Acoustic Isolation and have been accompanied by diverse optimization processes. The most important scientific and practical results of the investigations, will be summarized and discussed
MRLS A PRACTICAL ALTERNATIVE TO MRS?
TAK Mathews Chartered Engineer, Qualified Elevator Consultant, India | firstname.lastname@example.org
At the turn of this century, the proliferation of MRLs was one of the paradigm shifts to impact the elevator industry. Initially the MRL was introduced as a green alternative to the hydraulic elevators. It was pitched as a solution where height restrictions made machine room on top arrangements impossible. It was a solution confined to low rise buildings.
However, over the last decade, the MRL elevator is being pitched as a total replacement to the MR elevator with many suppliers refusing to provide a MR alternative even for high rise buildings.
This paper will critically examine the practicality of MRL elevators replacing MR elevators.
INNOVATIVE DRUM ELEVATORS: MINIMAL DRUM DIMENSIONS – SMALL ROPES
Prof. Dr.-Ing. Wolfram Vogel, Germany | email@example.com
Publicly certified expert for Elevator-, Rope- and Lifting Technologies“
In the past, drum elevators at first were the conveyor to make high-rise buildings possible. With increasing travel heights and upcoming safety devices – such as emergency breaks – the drum elevator lost its importance more and more. In these days the drum elevator again is an important alternative from the point of view of urban development, light weight and energy efficiency coupled with architectural future targets in the field of digitalization. The great advantage of drum elevators is based on the full utilization of shaft space. A combination of small diameter ratios drum to rope D/d with all safety-related items according to the rules of the standards and the lift directive allows an innovative elevator for a variety of applications. The paper presents new possibilities and chances coming with a statistically verified D/d=20 and a minimal safety factor in single layer drum elevator application followed by a completely new and patented spooling strategy. We report on the intensive research and development of this new products.
THE FIRST INTERNATIONAL ELEVATOR SAFETY STANDARDS
Dr. Lee E. Gray Senior Associate Dean, USA | firstname.lastname@example.org
This paper examines the creation and content of the first international elevator safety standards: Safety in the Construction of Lifts, published in 1939 by the International Labour Office. The proposed standards drew from materials gathered from eleven countries: Australia, Belgium, Finland, France, Germany, Great Britain, Italy, the Netherlands, Sweden, the Union of South Africa, and the United States. This important work, with its detailed text, extensive bibliography, and 98 illustrations, provides unique insights into early elevator codes and regulations. It also represents the first attempt to synthesize this diverse set of materials into a uniform set of international standards.
INCREASING RELIABILITY AND PRECISION OF EM ELEVATOR BRAKE MONITORING SENSORS
WARNER ELECTRIC EUROPE, Germany
Eric.Volant@altramotion.com | Bernd.Wimmer@altramotion.com | Cedric.Gomez@altramotion.com |email@example.com
The use of failsafe electromagnetic elevator brakes is defined in international and national guidelines, directives and norms. Microswitches or proximity sensors are commonly used for brake monitoring. According to the main elevator manufacturers, microswitches have a failure rate of 30-40% during the lifetime of the brake, proximity switches are close to 5-10%. The function of these switches & sensors is limited under the influence of environment and aging factors. Most common reasons are contact deterioration or hysteresis fluctuations within production batches and temperature influence. Using the contactless technology of integrated sensors will increase significantly the reliability of Electromagnetic fail safe brakes

Alessandro Cremaschi: email@example.com | Emanuele Eusebio: firstname.lastname@example.org
This is IoT technology applied to glass mirrors in the lift (or lifting platform) cars (patent pending), transforming common mirrors into interactive touch-screen videos (managed remotely via internet). Unlike traditional cabin video screens, our “magic mirror” has many different purposes:
-Touch-screen video display
– Digital signage and communication
– Enhanced emergency service (through an additional micro camera)
– Maintenance/servicing support (direct video/audio connection between HQ and maintenance personnel on site). The system is extremely light and thin, with no impact on cabin weight and space, rendering traditional video screens unnecessary.
SAFETY IN 2028, PREDICTING THE SAFETY LEVEL OF FUTURE STANDARDS
Tijmen Molema, Liftinstituut, The Nederland
email@example.com | firstname.lastname@example.org | email@example.com | John.vanVliet@liftinstituutholding.com
Standards evolve all the time: there are major differences between the first EN81-1 and the newest EN81-20. Most changes are initialized by “major events”: faults are discovered/ new visions are created, major accidents happen, or new technologies disrupt the industry. Other industries can be a precursor for the lift industries. If we analyse the changes of the standard from the history up to today and find their causes, it allows us to make a prediction for the changes in the future. Where are the upcoming challenges for the lift industry?

firstname.lastname@example.org | email@example.com | firstname.lastname@example.org
In this research, we have studied automated feature extraction techniques to calculate new features from raw sensor data provided by elevator data recording system. Another data called as maintenance data is used to find time periods for creating class variables. Calculated features attached with class variables are classified using machine learning approaches. Time periods start from fault reported by customer and end when maintenance is finished and reported. This research is useful in fault detection and identification for elevator system using machine learning approach. We have used accuracy, sensitivity and specificity as evaluation parameters for this research.
DIAGNOSTIC DEVICE FOR STEEL CORDS IN ESCALATOR HANDRAIL
Norimi Kodaira, Toshiaki Matsumoto, Japan
email@example.com | firstname.lastname@example.org | email@example.com
We provide escalator maintenance service to keep the condition of escalators optimal.
The handrails that passengers grip when they get on/off the escalators are important parts for passenger’s safety.
However, in rare cases, reinforcing steel cords in the handrails break and come out of the handrails because of their aged deterioration, and passengers might get injured. But we cannot inspect the codes directly, because they are embedded in the handrails. So we have developed a new diagnostic device to inspect the codes indirectly using the leakage magnetic flux flaw detection method and reduced the related defects by 50% or more.

We have developed a camera-based door sensor for elevators that detects people approaching to an elevator to prevent the collision between a passenger and the closing door. The new sensor has two advantages over conventional photo electronic sensors: wider detection area and precise motion detection. It can detect the difference between a person approaching the elevator cab and passing over the door at entrance area.
We have implemented the algorithm on an embedded system and run it in real time.

Elevators are indispensable in modern society as a vertical access infrastructure. As skyscraper buildings increase, the seismic design has been focused as essentials of superior reliabilities. The elevators were often suspended their services due to sway of buildings caused by earthquakes or heavy wind.
Toshiba Elevator and Building Systems Corporation successfully realized the advanced seismic performance capable of detecting seismic behavior instantaneously precisely and forwarding the data to a controller on a real-time basis. The controller simultaneously analyzes the data and sends the best command to the system. The applied function made it possible to avoid the frequent service suspension and to improve availability rate.
This paper presents a brief summary of the seismic design features.

Lars Hesselgren Director Research, UK | LHesselgren@plparchitecture.com
The advent of digitally controlled transportation systems will usher in a revolution in how we live in cities. Ultra-high rise buildings will put far greater demands on intelligent vertical transportation systems, and will also open up much greater opportunities for vertical living. PLP/Architecture SkyPod system is an illustration of what can be achieved and also point towards the complete integration of all urban transport systems, such as PLP/Architecture CarTube.
Since presenting at Elevcon 2014 in Paris further development of the SkyPod system has taken place and it presents a radical look at the future of vertical transportation.
ELEVATOR PLANNING FOR SUPER TALL TOWERS IN ASIAN CONTEXT
K. Rajah Venkatraman, Managing Director, Fortune Consultants, India | email@example.com
Super tall towers elevator planning is a challenging exercise by itself. This is further challenged in the Asian context due to various additional factors. The various design stages are being explained in the elevator planning for super towers and the additional considerations in Asian context. The traffic analysis, the circulation models, the regulation considerations, the supply aspects, the capability considerations all these are discussed in detail with case study review. The emphasise that in super tall towers elevators are to be viewed with greater significance and backbone importance is being elaborated with pragmatic design complexities in real time scenario. This also bears additional weightage due to the fact many more super tall towers are being envisaged in the Asian locations .
SUSPENSION MEANS – EQUALING LOADS TO EXTEND THEIR SERVICE LIVE
Tim Ebeling, Henning GmbH & Co. KG, Germany | Ebeling@Henning-GmbH.de
In recent years, increasing problems have been identified with excessive wear of the suspension means on lifts, particularly on MRL systems. The causes are numerous, but the load distribution within the rope set is of great importance. According to Prof. Feyrer’s well-known studies at the University of Stuttgart, the life of the entire rope set can be reduced by up to 40%, if one rope only deviates by 15% from average value of all the rope loads in the set. By utilizing a long known physical principle, a device for permanent installation has been developed with which the rope loads can be compensated optimally without external energy supply (even during the lift’s travel) in both new and existing facilities. The lecture will deal with the operating principle, the chosen design and the results at selected standard as well as high-rise elevators.
ELEVATOR MODERNIZATION – WHY IT IS RECOMMENDED TO REPLACE THE GEARLESS DC MOTOR
Risto Kontturi, Finland | firstname.lastname@example.org
Eero Keskinen, Finland | email@example.com
DC motor technology is outdated. When modernizing old gearless elevators having a DC motor it is recommended to replace them with latest technology. DC motors have not been used in new elevator installations anymore for the last 15–20 years. There starts to be limited support available from manufacturers and small repair providers. PWM-based DC drives place high stress on the existing motor windings insulation and increase the risk of bearing failure. Typically traction sheave is also worn out and requires machining or complete replacement. Modern safety codes require two independent brake systems, monitored separately, which might mean costly changes to the existing motor or hoisting system.
ADDED VALUE OF ANCHORS FOLLOWING AN APPROVAL STANDARD
Dr. Michael Merz/ Elevator Application Solutions, Principality of Lichtenstein
Guide rails and doors are fastened to concrete typically using stud anchors. Except for price and marking there is no obvious difference in appearance between a stud anchor following an approval standard and a non-approved anchor.
An increasing cost competitive environment challenges engineers to give reasons for the specification of approved anchors.
This paper evaluates the value added of modern anchoring approval standards involving the design, manufacturing, capacity testing of the anchor itself plus the design of the anchoring application in compression or tension zone of the base material and under seismic conditions.
FURTHER STUDY ON TOTAL POWER FACTOR OF A LIFT SYSTEM
W L Chan, Hong Kong Polytechnic University and IAEE (HK-China Branch) and Albert So, IAEE and U of Northampton, China & UK
The electrical parameter “Total Power Factor” (TPF in short) is extremely important in checking how good a power supply is supplying its load. This term has been used for more than a century with some changes in the method of evaluation in the sixties when power electronic drives started to become popular. For a standard 1-phase or 3-phase-4-wire or 3-phase-balanced system, the existing definition of TPF is perfect. However, most lift systems are operating on a 3-phase-3-wire power supply while the 3-phase voltages and currents are not 100% balanced based on our site measuring experience. In other words, all existing definitions of TPF do not apply to a lift system. A new definition of TPF mainly for lift systems was proposed and further study on this definition was recently carried out. This article serves to provide a summary on works done by us on this issue, hoping that the problem has ultimately been solved.
BENCHMARKING <J/KG-M> BY SIMULATIONS
Albert So, IAEE and U of Northampton, China & UK | firstname.lastname@example.org
Energy efficiency of lift systems is of major concern due to the global demand for sustainable development. At present, there are international and national standards on energy efficiency of lift systems but the availability of one parameter that can master both motor drive efficiency and traffic control is limited. Thirteen years ago, the concept of <J/kg-m> with a unit J/kgm was proposed by the author. It was included in the Technical Guide of the Building Energy Code of Hong Kong SAR. However, due to some technical and commercial difficulties, the number of systems with this parameter equipped is limited. It is therefore difficult to provide a solid figure of it for the purpose of benchmarking. In this article, results of different types of simulations, including different drive types, different traffic patterns, and different supervisory control methodologies, are reported. It can be shown that an acceptable system can achieve 50 J/kgm or below, a good system 40 J/kgm or below and an excellent system 30 J/kgm or below.
HISTORIC CHANGE IN ELEVATOR DOOR SENSORS- LIGHT CURTAINS ARE SET TO BECOME HISTORY, REPLACED BY INTELLIGENT TOF TECHNOLOGY
Christian-Erik Thöny ,CEO CEDES-Group, Switzerland | email@example.com
The latest state-of-the-art “time of flight technology” (TOF) has reached maturity.
It enables an entirely new approach to monitoring and controlling elevator doors or other mechanically-moving elements. In a disruptive way, light curtains will be replaced by a sensor much, much smaller yet simultaneously adding a completely new intelligent dimension.
Today’s light curtain functionality will be comprehensively replaced across the entire door front, with benefits such as entrance area monitoring, accurate people counting, preventive maintenance, UCM prevention, etc.
Not only is this additional functionality a real breakthrough, the 40 times smaller sensors significantly improve logistics and contributes to major cost savings.
FULFILLING THE POTENTIAL OF DOUBLE-DECK DESTINATION CONTROL SYSTEM
Dr. Janne Sorsa, Finland | firstname.lastname@example.org
KONE Corporation, Keilasatama 3, 02150 Espoo Finland
Double-deck elevators with the destination control system are used in tall buildings to reduce the core space occupied by elevators. The lunch traffic performance of such a system still limits potential space savings, which is largely due to the immediate assignment of passenger calls to elevators and decks. To solve the challenge, two novel optimization methods for an elevator group control system are introduced. First, uncertain near-future passenger arrivals are modelled by scenarios, which then define the optimal elevator routes in a robust manner. Second, the re-optimization of the call assignments gives maximum flexibility for the control to react to new passenger arrivals.
THE COMEBACK OF THE HYDRAULIC LIFT
By Thomas Birnbaum (ELCA), Ferhat Celik (Blain), Belgium
Luc Rivet, Secretary General | E-mail: email@example.com
The hydraulic lift was considered the ideal solution for low buildings, up to 7 stops with relatively low traffic until the 1980’s. Then, the will to reduce the energy consumption during use became prominent and the share of hydraulic lifts dwindled to 24% of the residential market. A new study by ITA, the laboratory of the University of Saragossa (Spain) compares the LCA’s of both hydraulic and traction lifts. The result is stunning: hydraulic lifts have a lighter environmental footprint than traction lifts for low buildings up to 7 stops, in usage categories 1, 2 and partly 3 (50, 150 and 300 trips/day).

The safety of elevator equipment is an imperative throughout the world. Elevator Codes and Standards are the de-facto universal means of ensuring safety and have evolved simultaneously with public expectations. Major economic growth in the Asia-Pacific Area (APA) has led to unprecedented urban development with corresponding demand for elevator equipment. The changing global economic structure has led to greater participation in elevator standards development by APA experts in ISO activities. In response to global demand, a series of ISO Prescriptive Standards will soon be published and together with enhanced ISO Performance-Based Standards will provide state-of-the-art norms for standard and innovative products.

5 experienced elevator companies came together and established R&D, production and logistics center.
The ability to design non-standard project requests accurately and in a timely manner and transfer them to production is a process that requires too much technical personnel and time and is error-prone. This process has been solved by the company’s parametric design program. With the help of this program participating companies can design their own elevators as they want. In case of approval, GETA can prepare the requests of participating companies as complete, error free and immediate production orders.
This program will be introduced in the presentation.
PREDICTIVE MAINTENANCE – SMART SERVICES ENABLED BY ADVANCED ANALYTICS
Rami Aro, Global Segment Manager Elevators & Escalators, Switzerland
Weidmüller Group with HQ in Detmold (DE)
Words like Smart Elevator, Big Data, Predictive Maintenance etc. are currently inspiring many elevator and escalator manufacturers. Based on predictive maintenance, guaranteed machine uptime is projected to deliver added value to new systems in the future. But more and more companies are realising that the expansion of data-based services provide them with real business advantage and such future-proof business models are set to leverage long-term customer loyalty. The methods employed by Advanced Analytics help to achieve this. Machine learning and artificial intelligence techniques allow machine behaviours of an elevator or escalator to be better understood by the manufacturer thereby revealing structures and patterns and providing new insight into data relationships. But the path to go need to be a well organised process. Weidmüller shows how to describe the use case and to establish a proof of concept, while the project team run through the traditional stages of data capture, integration, preparation, analysis, implementation and finally evaluate the economic benefit.

Moderator: Luc Rivet, ELCA, Belgium | email@example.com
Luc Rivet, Secretary General
The lighter environmental impact of hydraulic lifts is now clear for a majority of lifts installed (residential and low buildings) thanks to the comparative LCA’s of the ITA study (Saragossa University – Spain). The work method and results of the ITA study will be analysed in the different phases of the life of the lift. The environmental performance of the newest types of both traction and hydraulic lifts are compared in terms of usage categories over a theoretical lifetime of 20 years, to determine the areas of best performance for each type. The environmental results of modernization are also envisaged.
