About the author

Ramón Uriepero

Industrial engineer · Lift, industrial electrical and refrigeration technician · Hallwil AG (Switzerland)

More than 30 years of technical work on three continents, over 15 of them on lifts. His work on lifts and electrical installations began long before his engineering studies: from an experienced mentor he learned to take measurements on installations, find faults systematically and spot failures before they happen.

Since then he has worked in refineries, on oil tankers, in hotels and in factories. In Spain he looked after portfolios of more than 120 lifts, with 24/7 on-call duty and passenger rescue. In refrigeration and air conditioning he worked as a self-employed technician and in a fishing fleet, and he was a trainer in industrial instrumentation.

Industrial engineering degree, recognised in Spain as “Ingeniero Técnico Industrial”, mechanical specialisation (RD 967/2014)
Spanish professional certificate as a lift technician (IMAQ0110)
Training in photovoltaics, PLCs, robotics and variable frequency drives
