The FM4-LO contact wire measuring device is specially designed for static point measurement of contact wires. The laser beam of the FM4-LO determines the position of the catenary in relation to the track center as well as from the top of the rail.
This enables you to measure quickly and easily the:
- Contact wire height and stagger (zig-zag)
- Messenger wire height and stagger
- Bridge and tunnel heights, height of crossing power lines
- With accessories: Distance between pole leading edge and track center (FM4-LO Edge Configuration)
Applications
- 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
Funktionsumfang
Das Messgerät kann in Kombination mit der Messschiene Fahrdrahtlagen auf Spurweiten im Bereich von 750 – 1676 mm messen. Die Messungen können schnell und bei jedem Wetter durchgeführt werden.
Designed for construction site 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
Optional accessories
- LED lighting device for measurements in the dark
- Laser glasses for better visibility of the laser point
- Carrying bags and power adapter for more comfort
- Measuring bars for worldwide track gauges from 750 – 1676 mm
- Edge configuration for distance measurement from the pole leading edge to the track center
