GRP3000 Clearance Measurement System
GRP3000 integrates profiler into trolley which can be used to the clearance measurement of platform，bridge and overhead lines.
Profiler’s original point is the track center which is convenient for measuring the 2D coordinates of all the objects around the track. The measurement results can be exported in the form of graphs and reports, Profile data collection can be changed either with automatic profile measurement or manual object point targeting.
Application of GRP3000
● Maintenance measurement of operation lines
● Clearance measurement of rail line equipment and tunnel
● Rebuilding and design surveying of tunnel
● Measurement of slab track construction
● Measurement of urban railway system
