The Overhead line position measuring device FM4-LO is specially developed for the manual measurement of contact wire height and contact wire position (horizontal - and optional vertical - position of the wires in relation to the middle of track).
It measures quickly and comprehensively by using:
- laser,
- target optics (crosshair / optical lot) for quick targeting of the wire
- and measuring bar scale.
Applications of the overhead line equipment
- Project planning and construction of overhead line systems
- Regulatory and maintenance tasks on catenary and contact lines
- Calibration and control and of continuous, dynamic geometry measurement methods
- Optimized for flexible and mobile use in light and long-distance rail
Applications
- Quick and easy application to measure the catenary wire position
- position determination of the catenary, the static rest position of the contact wire electric railways
- statically-punctual measurement of the contact wire height above top of the rail catenary stagger measurement (zig-zag run) in relation to the track center
- further vertical distance measurements (suspension cable, bridge height, crossing power lines)
- use for erection of catenaries, assembly of and maintenance work on overhead contact lines
Designed for building sites environments
- target optics with crosshairs for quickly catenary detection in daylight and including bright sunshine
- non-contact laser distance measurement of catenary height, visible red laser spot on the target surface
- single or continuous measurements as useful search function and for differentiation of the distances
- automatic display illumination, LED back lit for target optic, stagger scale illumination
- special protection against dust and water for use at almost any weather conditions
- minimal staffing expenses for logistics and measurements
- without affecting traction power supply through contactless measurements and insulated track contact
- contactless measurement (optic, laser); therewith no interruption of the current supply during the measurements in the corresponding track section necessary
Flexibly to combine
- partable (2-parts) measuring bar with carrying bag for easy and protected transport in the car
- measuring bars for other track gauges or universal for several track gauges from 750 mm to 1676 mm
- measuring bars with imperial units (ft, in), changeover of units in the measuring instrument
- measuring device for track elevation
- catenary lighting device for night or tunnel work
- charger for rechargeable batteries
- laser visibility glasses
