Description
The EN-HE group of CERN operates more than 350 overhead travelling cranes, requiring a regular maintenance defined by CERN Safety Rules (GSI-M-1).An analysis made in 2020 concluded that important savings on preventive maintenance could be done by changing the actual strategy based on a fixed periodicity to a strategy based on the usage of each crane. To be able to implement such change, the usage of each crane has to be known and remotely communicated on a daily basis. This prerequisite is being fulfilled thanks to an economic solution based on IoT devices connected to each crane and relying on new LoRa network in surface and the LTE (GSM) network in underground locations.
This presentation focuses on the initial context including the financial stakes, the deployed solution based on IoT devices, the challenges and the results obtained.
