Asset management for extraction equipment in mining

Functions | Benefits | Range of Services | Sectors, Equipment


Excavators and crushers, shearer loaders and roadheaders: extraction equipment and connected conveyance lines and transport systems are exposed to extreme loads in mining. To operate these assets economically, you need reliable statements about the current condition of machinery.

zedas®asset provides this information. zedas®asset monitors your plants and generates diagnoses and forecasts about plant performance, load and wear and tear.  The system controls compliance with prescribed process parameters and analyses information according to economic indicators (KPI, LCC).  You can efficiently deploy your maintenance resources on this basis.

With zedas®asset you receive all the documents required for authority engineering, such as evidence on checking safety installations. The solution automatically determines technical parameters (KPI) for the optimum control of plant services and operations. Thanks to this you identify your machinery's and plant's capacity reserves and can make use of them for operations.

zedas®asset analyses historical plant data about plant operations and compiles forecasts from this.  As a result you can weigh up capex / opex alternatives, develop improvement potential for the operation of equipment and plants and work out efficient programmes to extend the plant lifecycle and increase its performance.

Function

With zedas®asset we monitor and document the whole lifecycle of plants and components and plan and manage maintenance and repairs depending on their load.

zedas®asset:

  • Records malfunctions, documents the causes of malfunctions and compiles a long-term analysis of the plant's operative behaviour
  • Controls and monitors the implementation of inspections and documents the components' degree of wear established when being changed
  • Compiles a malfunction and damage analysis from the operating history of maintenance carried out
  • Determines the plant and components load index using the long-term analysis of process data
  • Controls planning using the load and analysis of the plant's maintenance history and monitors and documents the implementation of future inspections, maintenance and repairs
  • Records the personnel and material costs of maintenance and repairs carried out


From the lifecycle history of the plants and components, zedas®asset determines:

  • KPI identifiers, which enable condition-based maintenance
  • Cost history of maintenance and repairs carried out on the assets
  • Forecast of costs for future (planned) maintenance work based on
    maintenance strategy and method chosen


zedas®asset ensures:

  • Data recording from any manufacturer's control and management systems without influencing the control technology (integration platform)
  • An assistance system to automatically instruct operator and maintenance personnel
  • The automatic checking of safety installations (e.g. limit switch) and corresponding evidence of check
  • Automated reporting and functional cockpits

Benefits for plant operations

  • Securing and improving conveyance performance:
    • Prevention of unplanned downtimes
    • Utilisation of capacity reserves
    • Optimisation of operation (operating point)
  • Reduction in costs:
    • Flexibility of maintenance according to operational requirements
    • Planning of maintenance measures depending on load
  • Shortening of planned plant outages:
    • use of preparation time in case of deterioration in condition
    • interdisciplinary bundling and coordinating of maintenance measures (mechanical, electrical, hydraulic)
  • Support of fast decision-making processes
  • Development and use of a basis of knowledge to improve plant operation
    and maintenance
  • Support of increased performance and extended lifecycle
