Krab LPS: Track Geometry, OCS, and Clearance Inspections
Looking for a way to measure full track geometry and perform track clearance and OCS inspections simultaneously? If the answer is yes, then the KZV Krab LPS is the perfect solution for you.
The Krab LPS provides full track geometry including gauge, cross level, twist, horizontal alignment (short and long) as well as Surface/Top (short and long) and is also equipped with a camera and lidar system for scanning of the overhead electrification system and the right-of-way.
The camera system is designed to provide high quality track images day or night and the lidar system captures a detailed 3D point cloud of the entire track environment as the unit is pushed along the track.
Office analysis software is included for geometry reporting as well as fully automated detection and mapping of platform distances to top of rail as well as OCS Height and Stagger. Track clearance inspections can also be automatically performed using custom rolling stock dimensions.

The Support that You Need
If you’re considering purchasing a geometry trolley from a generalist railway supplier with tens, hundreds, or thousands of unrelated SKUs you might want to think twice.
A track geometry trolley is a specialized piece of equipment that requires configuration of the appropriate signal filters for your network, implementation of your geometry limits, configuration of geometry graphs for reporting, and training of your staff in both field acquisiton and office data processing.
Make sure that your supplier takes the time to show you that they have the necessary expertise to configure and use the included software and that they include a full training program that covers both field acquisition and detailed analysis of geometry data in the office.
As actual users of KZV equipment, PrecisionTrack staff are well familiar with both field operation and office data processing and have the first-hand experience and expertise required to properly configure KZV trolley field software (KrabDroid, KrabOnBoard, KrabCamera) and KZV office software applications (Krab 11).
