The long-chord track survey system for precise track works
Proven measuring principle – optimized for track works
- Long chord method
- Combined survey of inner track geometry and absolute position in one run
- Absolute track accuracy 1 mm
- Correction data in real-time
- Fully automatic control point measurement
- Best survey performance
- More than 80 % cost savings compared to traditional methods
Modular system design – optimized for toughest project conditions
- Flexible system operation: twin-trolley mode or tripod mode
- Modular system upgrading
- Safe digital data handling – from measurement to final transfer of correction data
- Easy handling, simple transportation
- Flexible measuring mode
- No geodetic skills required
- LED-lighting for secure work at night
Twin-trolley mode: High performance for long track sections
- 1st choice for measurements during track closures
- Measuring performance up to 2500 m/h
- Length of reference chord of up to 250 m
- Measuring system GRP 1000 consisting of precision sensors for gauge, superelevation and distance, prism column and ruggedized notebook
- Measuring system GRP TSC+ with precision sensors and tachymeter on automatic self-levelling tribrach
- Extendable to two independent single trolley systems (for alternate operation in tripod mode)
Tripod mode: Greatest flexibility under demanding project conditions
- Ideal for shorter track sections, e.g. turnouts, multi-track sections and projects with limited track access
- Length of reference chord of up to 400 m Measuring system GRP 1000
- Tachymeter on tripod (optional with automatic self-levelling tribrach)
- Flex-Stop-Function for immediate measurement interruption and track release
- Upgradable with second measuring trolley at any time
