The CERN EP department has recently launched a process in view of starting in 2020 an R&D programme on new Detector Technologies. Detector Mechanics is one of the main themes within which the specific and focused R&D activities are planned to be. The current target is to provide by November 2018 a report summarizing the R&D programme proposal. We will describe the on-going process of this R&D programme launch, which topics are being considered for the Detector Mechanics R&D and explain how parties, also from outside from CERN EP, may contribute. More information on the R&D initiative is available in https://ep-dep.web.cern.ch/rd-experimental-technologies and on the Detector Mechanics working group in https://espace.cern.ch/ep-rdet-wg4-mech.
