Measurement Systems

KRAB S-LIGHT

Lightweight and compact full track geometry trolley. Wide range of accessories. Both vignole and grooved rails. 32 kg, 15 km/h, 8-hour battery.

KRAB System Live Rail Test

The KRAB trolley during a live rail test, measuring track geometry and rail profiles in real field conditions.

Also for: KRAB U-LIGHT, KRAB Heavy (84-09SA)

Assembly and Operation of KRAB S-LIGHT

KRAB S-LIGHT on the track: a light trolley one person can lift clear of the rails, measuring track geometry from zero speed with no warm-up.

Assembly of Your KRAB System Training

Step by step from unpacking the components to a trolley ready to measure. Useful for a first-time user and as a refresher before a measurement run.

Also for: KRAB U-LIGHT, KRAB Heavy (84-09SA)

Switch Measurement with Our Trolleys Training

How to set up, run and evaluate a measurement inside a switch: geometry and rail profiles in complex switch areas, collected without disrupting traffic and processed into a maintenance report.

Also for: KRAB U-LIGHT, KRAB Heavy (84-09SA), KrabDroid 3.0

Measuring Through a Frog Training

The correct procedure for approaching and crossing a frog with a KRAB trolley, so that the measurement stays uninterrupted and the operator stays safe.

Also for: KRAB U-LIGHT, KRAB Heavy (84-09SA), KrabDroid 3.0

KRAB Heavy (84-09SA)

Heavy-duty trolley for track geometry and rail profile measurement, towed behind a railway vehicle at up to 25 km/h.

LPS - Laser Profile Scanner

Track clearance scanner with two rotating lasers — tunnels, platforms, overhead line equipment (OLE), vegetation, plus track geometry

LPS Scanner

The LPS laser scanner on a KRAB trolley, capturing high-resolution 3D profiles of tunnels, platforms, overhead wires and vegetation while measuring track geometry and rail profiles in the same pass.

Also for: LPS Evaluation Suite

SPIDER

SPIDER electronic wheel diameter measuring device for railway and tram vehicles — 1.3 kg, 0.003 mm precision, optional wireless Bluetooth readout

MMD

Measuring undercarriages built to order for a customer's rail vehicle — track geometry under load at ~40 km/h, proven on Czech measuring cars and a towed measuring wagon in Finland
