Ultrasonic Hand Equipment MT 95

MT 95 ultrasonic hand equipment is used to inspect tracks for hidden faults. The equipment is primarily used to inspect critical spots such as welds, switch points and rail joints. Hidden faults in the rail, reported by other, high speed, measurement systems, can be evaluated precisely with the MT 95 in order to take all necessary correction measures. The hand inspection equipment is also used for quality inspection of all rail welds.

The MT 95 has a digital memory oscilloscope, which transfers results to a computer. The data and error messages are evaluated, stored and printed on site. Corresponding error documentation is produced on the computer also if the data are loaded for external processing and storage.

Georadar

Georadar allows swift, inexpensive and precise inspection of a rail's foundations. Contrary to expensive point drilling, a complete image of the ground structure up to five metres deep is obtained, with depths up to 20 metres possible. Measurements, accurate to a centimetre, of the strength of the ballast bed, PSS, FSS, pollution, ballast bags, silt, and water in the foundation layer are possible. Georadar is the ideal means for quality inspection after construction, soil sanitation and so on. The flexible, compact Georadar hand measurement system is used for special inspection on short route sections, switches and stations. The portable, on-rail platform is pulled manually and can be lifted off the rail in the shortest possible time.

Inspections on longer route sections is undertaken at up to 40 kph on the EM-SAT inspection vehicle (see picture) or SKL installed system.

Rail and switch equipment SGMT5

The Rail and switch equipment SGMT5 is a mobile instrument for the measurement, recording, and presentation of the rail geometry and switch parameters. Items measured are gauge, superelevation, twist, the switch and the distance covered. The operator sets markers on the graphics at those locations showing exceptional values. The data are shown both in graphics and as stored digitally. The integrated computer makes automatic measurement programmes such as the complete implementation of point investigations according to Ril 821.2005 norms of the DB AG possible. The data are naturally available for further processing and archiving. The software includes the automatic generation of a switch investigation sheet according to the Ril 821.2005 norms. The SGMT5 is accepted by DB AG as measurement method for formal approval.

SPG 2 handheld ultrasonic measuring device

The SPG 2 is an advanced tool for mechanized ultrasonic testing because of the combined use of one vertical probe and two angled probes. All sensitivity adjustment and the defect allocation of the probes are done in real time by the control box. Therefore it is possible to check the rail for lengthwise and crosswise defects simultaneously in one work step.

Experiences in practical field testing have led to further improvements in the design of the SPG 2. Improved probe holders guarantee constant contact to the rail.

Reading the screen is easier now with tilt- and height-adjustable instrument holder. The SPG 2 used at Eurailscout has been approved for testing at DB AG.

Eddy current measuring instrument

The track network is exposed to very high loads because of the present-day rail traffic. Defects close to the surface in the running edge of rails can arise via the wheel-rail contact, especially in curved locations. These cracks, which are called head checks, can significantly increase the risk of a rail break when they grow.

The testing of the rails with an eddy current aids in the detection and evaluation of defects close to the surface. Other inhomogeneities such as grooves, ghost lines and skid spots are likewise found. It is therefore possible to follow the development of damage in the surface area early on, as well as to make plans for the remedy of the damage in an optimal fashion and to check the success of these plans.
