The KRAB Slight system is the latest step of Krab evolution. It was designed with focus on low weight and easy manipulation. The measurement speed is limited to 15 km/h. Thanks to its low weight the trolley can be easily removed from the track by single person. Measuring computer provides enough capacity to store recorded data (min.2000 km). Measuring trolley can be designed for measuring of multiple track gauges in a range of 760 mm to 1676 mm.

RECORDED VALUES:

BASIC TECHNICAL INFO:

Trolley weight: 32 kg basic version

Trolley battery operation time: 20 h

Range of working temperature: -5÷55 °C

Measuring step: 0,25 m standard (adjustable)

This classic measuring trolley has been present on a railway market for many years. Its robust construction and average weight of 67 kg makes it perfect for hand-pushed measuring as well as for occasional coupling with a railway vehicle.

Krab 84.09 SA is conceptually similar to Krab 84.09 but it is modified for coupling with a railway vehicle. It also contains derailment prevention and derailment protection systems. The wheels of Krab 84.09 SA have larger diameter, which together with a total weight of about 120 kg, ensures greater in-track stability.

GEKON is a measuring equipment designed for contactless corrugation measuring of both vignol and grooved rails. GEKON can be used for evaluation of railhead surface microgeometry evaluation.

GEKON allows to measure continuosly or per sections. Measurement results can be compared with EN 13231-3 standard.
GEKON is composed of manually driven trolley and measuring computer, which serves as a data-logger and it can also evaluate the measured data. Trolley is light and compact. It can be removed from the track and returned back within seconds. Measurement can be done on an operated track.

Double Gekon is a measuring equipment designed for contactless corrugation measuring of both vignol and grooved rails. GEKON can be used for evaluation of railhead surface microgeometry evaluation.

Double Gekon allows to measure continuosly or per sections. Measurement results can be compared with EN 13231-3 standard.

Double Gekon is composed of manually driven trolley and measuring computer, which serves as a data-logger and it can also evaluate the measured data. Trolley is light and compact. It can be removed from the track and returned back within seconds. Measurement can be done on an operated track.

LPS scanner is designed for checking the clearance around the measured track. It can be used to check the tunnel tube, platforms, vegetation around the track, catenary poles or any other object placed along the track. Based on Krab trolley, the system is capable to measure a complete track geometry.

LPS is equipped with camera, which is synchronized with kilometric position. This camera helps to determine the measurement during the evaluation.

LPS trolley is designed for manual operation. Standard measuring speed is walking speed (4 kph). Scanner resolution at this speed is 2 x 2 cm with cross sections made every 4 cm. When the measurement is finished, data can be evaluated directly on the trolley computer Alternatively, the data can be transferred to office PC with evaluation software.

TURTLE is a measuring trolley designed to pulled behind a railway vehicule.
TURTLE is specially designed for tramway tracks. It can measure both vignol and grooved rail tracks.
It measures selected parameters of track geometry and wear profile of both rails. Pictures of the track are automatically taken by camera in predefined interval and can be viewed together with the rail profiles and track geometry data.

The Krab NCI is the newest product of our Krab family.
It was designed with a focus on low weight and easy operation using non-contact technology.
This concept enables the measurement of track geometry as well as rail profiles.
The principle of measuring with the chord is kept and enhanced by coordination with the inertial sensors.

VAL track recording trolley

RWT Trolley is a special designed diagnostics device of the so-called VAL tracks, the special designed track
to guide the vehicles having rubber wheels.
The trolley is equipped by numbers of contact and non-contact
electronics sensors to measure the wide amount of critical geometry dimensions of the track structures.

• Rail Roughness Measurement
• Evaluation of Noise Propagation
• Environment Problem of The Railway

TROLLEY DESIGN
SALAMANDER consists of a measuring unit driven by electric engine and external control computer for Androids OS (Smartphone, tablet or notebook). Both parts are linked by WIFI wireless or Ethernet cable. The Device can be pushed manually as well as self-propelled driven by engine depending on selected work strategy. The laser sensors with the necessary drive and electronic units transfers the acquired data to a computer.
