Assessment of brake problems snow clearing vehicle

Customer: ZAUGG AG EGGIWIL, Switzerland

Project tasks

  • Independent assessment of the braking performance of the snow removal vehicle ZRR10000M Trafikverket

Our approach

The task included research of existing standards and operational regulations, the investigation of the implication in case of a lining change as well as consultations with brake suppliers / operators. Based on these technical and operational data, experiences and general conditions, PROSE prepared an independent investigation and assessment of the mentioned brake problems under severe winter conditions including recommendations for action.

Customer benefit

The assessment is used for submission to the vehicle operator. With the various solutions and recommended actions adapted to the vehicle, reliable operation of the vehicle can be achieved. Thus, the customer can fulfill the obligations towards the operator. Furthermore, the report serves as a basis for the approval with corresponding argumentations, which makes it easier for the customer to appear before the registration office and the end customer.

 

Verification of clearance between infrastructure gauge and infrastructure

Customer: Stadtwerke München GmbH (SWM), Germany

Project tasks

  • Support of the SWM project management in the technical evaluation of the results of the infrastructure survey
  • Interpretation of the results with regard to the requirements resulting from §18 of the BOStrab (German regulation on the construction and operation of tramways)
  • Recommendation of the measures to be taken
  • Preparation of the final report of the initial survey for the individual metro lines for submission to the technical supervisory authority

Our Approach

​With laser surveying, the existing installations are recorded with a precision that was previously impossible. PROSE supports the SWM project management in the technical evaluation of the results of the infrastructure survey. This includes the interpretation about the requirements resulting from §18 of the BOStrab as well as the measures to be taken. In addition, PROSE prepares the final report of the initial survey for the individual metro lines for submission to the technical supervisory authority.

Customer benefit

PROSE has experts with many years of expertise regarding the interaction of infrastructure and vehicle and especially regarding the clearance of the light area. This enables PROSE to advise clients on the interpretation of the applicable guidelines in case of ambiguous facts. PROSE was able to prove to SWM that several objects, which were initially classified as violating the clearance, do not pose a threat regarding the clearance. Thus, the customer could avoid a cost-intensive dismantling of these objects.

Assessment of the safety against derailment of a historic fleet running on “bicycle safe” track

Customer: Basler Verkehrs-Betriebe (BVB), Switzerland

Project tasks

  • Recording of vehicle data of the historical fleet
  • Clustering of the vehicles
  • Measurement of the “velogleis” system on site
  • Evaluation of the relevant parameters and classification regarding the applicability

Our Approach

By means of an objective computational method, PROSE evaluates the usability of the vehicles. The investigation of the derailment safety of the historical vehicles is performed regarding the track-related system parameters at the according location. Since such vehicle-technical data are only available to a limited extent for historic vehicles, the running gear design of the vehicles is additionally examined on site in the maintenance pit. For the evaluation regarding the usability, the wheel contact force is analyzed among other topics and the vehicle groups are evaluated according to their use (yes, no, under certain conditions) and documented in a report.

Customer benefit

PROSE’s expertise provides the customer with a statement about the usability of their historic vehicles over the installed track system “velogleis”.
