Levelling system for rail technology

摘要

The system has an electronic hose scale (5) comprising sensors (B1-B4) for detecting height difference between measuring points that are connected with one another. An evaluation unit detects and evaluates sensor data, and a height-adjustable actuator is attached to each measuring point. An electronic controller controls the actuators in such a manner that the actuators move the measuring points upward and downward till all the measuring points lie in a horizontal plane. The evaluation unit has a data memory for storing the sensor data, and the sensors are connected to a coupling surface. Independent claims are also included for the following: (1) a method for leveling a coach body (2) a method for measuring a rail.
