1. What is the TYJJ-2 OHL Railway Laser Height And Stagger Gauge?
The TYJJ-2 is an intelligent, all-in-one overhead line (OHL) measuring instrument that combines laser ranging, grating angular measurement, track gauge sensing and horizontal measurement modules to capture height, stagger and related OHL parameters for electrified railways.
2. Which measurement parameters does the TYJJ-2 provide and what are their ranges/accuracies?
Key specifications: Cable height 3000–15000 mm, ±3 mm; Cable stagger ±3000 mm, ±4 mm; Cross center ±3 mm; Elevation difference at 500 mm ±4 mm; Track gauge 1410–1470 mm, ±0.5 mm; Super-elevation (horizontal) ±200 mm, ±0.5 mm. Additional parameters such as red line, mast gauge, elevation differences, overlap section and distances between lines have typical accuracies of ±4 mm; mast span up to 35000 mm, ±5 mm.
3. How is the TYJJ-2 physically configured for field measurement?
The system is an all-in-one machine where the measuring host mounts to a horizontal measuring frame (a horizontal bar placed between the rails). The host performs laser ranging and vertical angle measurement while the frame supports the host and measures track gauge and horizontal tilt among other tasks.
4. What core technologies are used in the TYJJ-2?
The TYJJ-2 integrates laser non-cooperative target ranging, grating angular measurement, a two-dimensional coordinate measuring approach and sensor information fusion to produce accurate OHL parameter measurements.
5. Can the TYJJ-2 integrate with digital railway management platforms?
Yes. The system is designed to provide digital measurement outputs suitable for creating and populating OHL parameter databases and digital management platforms. Data export and integration options can be provided or customized to match customer systems.
6. Is the TYJJ-2 suitable for standard gauge track?
Yes. The track gauge measurement range of 1410–1470 mm covers the standard gauge (1435 mm). For other gauges or special requirements, contact the manufacturer for customization options.
7. How portable and field-ready is the instrument?
The TYJJ-2 is designed for on-track field use with a robust measuring frame and host. It is intended for installation between rails and for routine field measurement tasks. Specific weight, dimensions and power options vary by configuration—refer to the product datasheet or contact sales for details.
8. What power and operating conditions are required?
Power and environmental specifications depend on the chosen configuration. The system is engineered for outdoor railway use; exact operating temperature ranges, power supply (battery or mains) and ingress protection ratings are provided in the detailed datasheet or upon request.
9. How is the unit calibrated and how often should it be calibrated?
The TYJJ-2 supports factory calibration and field verification procedures. Periodic calibration is recommended according to operating intensity and local regulations—typically annual or semi-annual for heavy use. The manufacturer provides calibration services and guidance to maintain traceability to standards.
10. What maintenance and care does the TYJJ-2 require?
Basic maintenance includes keeping optical windows and laser apertures clean, checking mechanical connections of the measuring frame, protecting electronics from moisture and shock, and performing routine calibration checks. Detailed maintenance schedules are provided in the user manual.
11. What safety precautions are required when using the TYJJ-2?
The instrument uses laser ranging and must be operated according to laser safety guidelines. Operators should wear required PPE, avoid pointing the laser at people, and follow railway operational safety procedures (lookouts, permits, and traffic protection) when working on or near tracks.
12. What data formats and reporting options are available?
The TYJJ-2 produces digital measurement data suitable for reporting and database use. Common export formats and custom reporting templates can be provided to match client requirements. Contact the vendor to confirm supported formats (e.g., CSV, Excel, or integration interfaces) for your deployment.
13. How fast are measurements and what is the survey throughput?
Point measurement times are rapid (suitable for field surveying), but total survey throughput depends on the number of measurement points, site conditions and operator workflow. For planning purposes, the vendor can provide sample cycle times and typical survey productivity estimates.
14. What accessories and components are included or available?
A typical package includes the measuring host, measuring frame (horizontal bar), field software and basic accessories (transport case, mounting hardware). Optional accessories, power solutions, spare parts and software integration packages are available—consult sales for configurable kits.
15. What support, training and warranty are provided?
The manufacturer provides technical support, user training, on-site commissioning (optional) and after-sales service. Warranty terms vary by region and configuration—ask your sales representative for specific warranty length and service options.
