installed as part of the contract with Øresundtog. Automatic measurement of the profile of the wheels should reveal wear and damage at an early stage. The data collected is used to optimise maintenance, extend the life of the wheels, and to prevent worsening damage affecting operation.
In sum, these activities will help to reduce time spent in the workshops, while maintaining safety and high quality in the overall delivery of train sets.
Lifetime of old equipment
Trains have a long service life; in many cases they remain in operation for
over 40 years. This can make it hard
to procure spare parts, as parts go out of production before the trains have reached the end of their service lives. One way in which Mantena is meeting this challenge is the use of 3D scanning, so as to be able to produce its own replacement parts and repair damaged components.
This technology allows us to keep trains in operation for longer, as an affordable and efficient solution for customers. Mantena has partners in additive manufacturing and 3D printing, both to create new parts and to overhaul and repair existing parts.
By adopting new technology, Mantena sees great opportunities to reuse more of the materials used in overhaul work and so also reduce waste.
3D scanning for documentation
Visual inspection and mapping of damage and repairs can be a very complex and time-consuming job with conventional measurement methods. It is also difficult to assess and document deviations in geometric tolerances with manual measurements. 3D scanning allows us to do this job more accurately and efficiently.
By comparing scan and reference geometry in an application, a digital targeted deviation report can be generated. We define acceptance criteria ourselves on the basis of requirements from the manufacturer, train owner or customer. Having this expertise within the company allows any
discrepancies to be detected at earlier times in the repair process. This results in efficient processes, cost-saving solutions and better quality.
New internal operating models
Mantena follows the Operational Excellence Programme (OEP) in its day- to-day work, which creates a common understanding and enables us to develop and implement a flow-oriented and self-improving business process. Operational Excellence is intended to support the whole organisation with knowledge and a common language to provide for an optimal flow throughout the value chain. Mantena has chosen to collaborate with the researcher Niklas Modig, who has extensive experience of change management.
In 2020, Group management and the main elected representatives went through the first part of the programme, the Foundation Course. The Foundation Course was given for all employees
in 2021, and the Transformation Programme will be run in several parts of the Group in 2022.
New business models
Mantena’s services are based on long experience of maintenance combined with a great capacity for innovation.
A strong focus on new technologies, combined with a willingness to pick up knowledge and experience from other industries such as aerospace and defence, should provide a basis for new business models and services for our customers and partners.
Mantena will meet customer needs through partnerships where all products and services are delivered efficiently.
OPTIMISATION WILL ALLOW BOTH MANTENA AND ITS CUSTOMERS TO DEVOTE LESS RESOURCES TO THE WORK OF MAINTAINING THE TRAINS.
