The current EN 81-1 Norm is going to be replaced by EN 81-20 / 50: 2014 on August 31st, 2017. This paper covers some topics to be considered in the implementation of the new standard. In addition, innovative approaches for alternative suspension system and safety devices can also be taken by means of risk analysis, according to the Lift Directive 2014/33 / EU: the introduction of mechatronic systems opens up entirely new ways to dispense with conventional speed limiters in the near future. To implement such systems, fails-safe electromechanical brakes must also be developed. This is part of a trend in the lift business to reduce the number of required components and integrate them to optimise the use of available shaft space. The challenges to master this technology in the context of a complete lifts, and how to cope with the increasing complexity for installation, testing and maintenance by developing complete 3D models for each project are also discussed in this article.
