Delivery of four dummy bogies

Project tasks

  • Project management
  • Manufacture

Our Approach

PROSE was commissioned to develop and manufacture four customised dummy bogies for the depot. The main challenge was to design robust bogies suitable for use in the demanding conditions of a workshop environment. These bogies not only need to have a high load capacity but also have to offer flexible adaptability to different vehicle types and maintenance requirements of the depot. The manufacturing process required carefully selecting materials and technologies that ensure long-term durability and resistance to mechanical stresses and environmental influences. In addition, special attention was paid to ergonomics and user-friendliness to ensure the safety of depot employees and increase the efficiency of maintenance processes. The technical specifications were worked out in detail in close cooperation with the customer to ensure that the finished bogies are optimally adapted to the depot’s specific requirements and existing infrastructure.

PROSE tackled this task with a focused approach to quality and functionality. The four dummy-bogies were manufactured under strict quality control and using high-quality materials. Each bogie was carefully designed to meet the specific requirements of the depot, with particular attention paid to durability and ease of maintenance. The noise reduction target of >1dB set at the beginning of the project was successfully achieved with a theoretical analysis.

Customer benefit

​The provision of these four customised dummy-bogies offers the customer considerable advantages. Thanks to the improved reliability and robustness of the bogies, maintenance work can be carried out more efficiently and safely. This leads to a significant reduction in downtime and an increase in operational safety in the depot. The customised bogies, therefore, not only support daily routines but also help to improve the service life and performance of the vehicles maintained in the depot.

 

   

Gearbox investigation on vehicles

Project tasks

  • Project management
  • Create a feasibility study
  • Test proposals based on the preliminary study
  • Evaluation from tests
  • Recommendations

Our Approach

The feasibility study involved testing the sealing proposals recommended by PROSE on two different gearboxes of the vehicle. One gearbox was found to have a minor leakage, while the second gearbox showed similar levels of leakage as before, despite the use of a sealing compound and a regular O-seal. These tests helped to evaluate the effectiveness of the various proposed sealing methods and provided valuable data for the further development of the solutions.

Customer benefit

​Based on the results of the tests, PROSE can now make specific recommendations for further steps. PROSE, therefore, recommends that the next step is to test the X-seal and simultaneously apply two lines of sealant to the motor output shaft. This recommendation is based on the observed performance of the tested seal variants and aims to develop a more robust solution to prevent oil leakage. This strategic approach allows the customer to make targeted adjustments and improvements to resolve the problem in the long term and improve the operational reliability and service life of the gearbox.

Vehicle procurement – Manufacturing Supervision, Quality Control and Factory Tests

Customer: various customer

Project tasks

  • Acceptance of the welded car bodies / bogie frames
  • Paint inspection and acceptance
  • Intermediate acceptance of main electrical components
  • Intermediate acceptance of interior fittings
  • Factory acceptance/customer acceptance

Our Approach

By regular participation in the vehicle acceptance tests and constant coordination with the team of the vehicle manufacturer, PROSE checks the quality of the production. The customer is permanently kept up to date by the acceptance team regarding the progress of the production as well as possible complications or deadline postponements. He immediately receives the results of the production controls and acceptances and can follow up changes, modifications etc.

The dates for the acceptance of components, intermediate assembly stands and vehicles ready for delivery follow the production plan but are also handled operationally and flexibly in order to be able to react to specific occasions. In this way, control of the construction process is always ensured and there is the possibility of intervention in the event of difficulties such as quality slumps, scheduling, supply, or capacity problems.

Customer benefit

With manufacturing supervision, the manufacturer’s quality assurance process is checked and monitored in addition to the product quality, because every vehicle has gone through this process before it is presented for factory acceptance. Continuous construction supervision ensures consistent quality at a high level.
