GGT GMEINDER GETRIEBETECHNIK GmbH and Stimio join forces for a predictive maintenance solution for railway gearboxes

GGT GMEINDER GETRIEBETECHNIK GmbH and Stimio join forces for a predictive maintenance solution for gearboxes in railway applications.

Mosbach (GER), Nantes (FRA), November, 24, 2022 – GGT GMEINDER GETRIEBETECHNIK GmbH, specializing in development, designing, manufacturing and maintaining of wheel set gearboxes for rail-bound vehicles and Stimio, specializing in IoT monitoring and predictive maintenance solutions to industry, have joined forces to enable prognostic maintenance of railway gearboxes.

GGT GMEINDER GETRIEBETECHNIK GmbH has recently developed an innovative oil-condition sensor that monitors all critical operating data from the gearbox. The GGT-GearSaver® sensor can monitor metal abrasion, temperature, oil quality, relative humidity, oil level – and thus help determine the time until the next oil change. With this new sensor, the service life and operating costs of gearboxes can be optimized. GGT-GearSaver® can be mounted in nearly any gearbox from any manufacturer.

GMEINDER team called upon Stimio’s digitalization expertise to add connectivity to the GGT-GearSaver® sensor, thus allowing collected data to be sent to the cloud in a secure and reliable manner. Stimio’s Railnet, a railway-certified IoT gateway, already greatly deployed within Stimio’s historical customer SNCF, is used to collect and transmit data from up to 8 GGT-GearSaver® sensors. Gathered data will be processed by GGT’s experts and made available to its customers via Oxygen, Stimio’s Cloud Platform, giving them insights, maintenance recommendations and action prescriptions.


“We are pleased to have GGT as a customer. This partnership once again demonstrates the modularity of our solution. As leaders in the digitalization of railways, increasing efficiency and availability, reducing maintenance and operating costs are key factors that we take very seriously and that motivate us on a daily basis,” says David Dorval, CEO of Stimio.


Dr. Wolfgang Fischer, CEO of GGT GMEINDER GETRIEBETECHNIK GmbH, “We found with Stimio the perfect partner to integrate our GGT-GearSaver® system. By combining our sensor technology with Stimio’s hardware and digital expertise, we bring value to our customers and help them to lower the total cost of ownership for railway gearboxes.“
