According to Mining News Pro - TPA is an intelligent, sensor-based solution for all machines required in the excavation process – from the bucketwheel excavator (BWE) and belt wagon to the tripper car. TPA automation system ensures transfer point alignment by following a set of steps:

-Measuring the position of each mobile machine involved in the excavation process by means of radar and GPS sensors
-Evaluating the current machine constellation
-Sending individual commands to different actuators when detecting deviation on the optimal transfer point position
-Stopping the material flow if the deviation exceeds a predefined value

The TPA user interface offers miners a real-time visualisation of a machine’s constellation and any transfer point misalignment. It also allows users to edit parameters and show diagnosis information, alarms and trend graphics.
