1. General The measuring devices of the R-series (= models RA | RCA | RCS | RCFF) are analogue instruments for the checking of vignole and grooved rails on railway and tram systems. The measuring devices are modular in design, and can be custom-configured. In order to ensure correct application, please be sure to comply with the nominal track gauges specified in chapter 6 (Technical data) as well as the permissible measuring ranges.
2. Commissioning 2.1 Device description The measuring device consists of a solid anodised aluminium tube. In the separable variant (→ Options) the measuring device can be separated asymmetrically.

2.2 Preparations The measuring devices of the R-series are state-of-the-art units, guaranteeing a high degree of reliability. However, that reliability can only be attained in practice if all the necessary measures are taken. It falls within the duty of care of the company operating the measuring device to ensure that those measures are taken, and to monitor their implementation.
Calibrating the spirit level The spirit level must be checked and adjusted as necessary prior to use. Preliminary remarks The permissible tolerance for cant measurements is ± 1 mm. The cant measurement fine adjuster mechanism is optimised for clockwise operation. Procedure On a section of track with a maximum cant of 20 mm, position the measuring device and measure the cant (= 1...
3. Operation | Measurement When measuring, both measuring bolts of the broad contact must be contacting on the rail head in order to avoid measurement inaccuracies resulting from angle errors. 3.1 Measuring track gauge (RA | RCA | RCS | RCFF) Position the measuring device on the track at the measuring point.
3.2 Measuring flangeway clearance (RA | RCA) Position the measuring device on the track at the measuring point. Push the sliding bolt towards the track construction (e.g. check rail or wing rail) until the measuring bolt makes contact. Read off the measured value.
3.4 Measuring back-to-back distance (RA | RCA) Position the measuring device on the track at the measuring point. Fix it in place such that the measuring bolt of the flangeway slider makes contact on the inside (i.e. on the check rail)! With the fine adjuster, turn the measuring bolt of the narrow contact towards the wing rail as far as it will go and read off the measured value.

3.5 Cant (RCA | RCS | RCFF) Position the measuring device on the track at the measuring point. Turn the air bubble in the spirit level to the zero setting using the cant pivot handle. Read off the measured value. Figure 6: Measuring cant Optimum cant measurement accuracy is assured when the measured value is approached on the readout scale from left to right (= i.e.
4.2 Option -P (blade inspection adapter) Detach the blade inspection adapter from the retaining bolt and slot it onto the measuring bolt. For the test conditions refer to the relevant inspection standards. Figure 11 Figure 12 4.3 Option -H (crossing tip inclination) Position the measuring device on the crossing.
4.5 Option -R20 (flangeway 20 mm) This option enables the measurement of grooved rails with flangeway clearances of ≥ 20 mm. 4.6 Option -W (changeable probes) Changeable bolts can be used to adapt the measuring device variably to country-specific standards and/or different rail types (e.g.
5. EC Declaration of Conformity as per Annex II A of the Machinery Directive (98/37/EC) The manufacturer: Vogel & Plötscher GmbH + Co. KG Geldermannstrasse 4 79206 Breisach hereby declares that the measuring devices described here of the type RA | RCA | RCS | RCFF comply with the following applicable requirements: 98/37/EC, Annex I...
7. Care and maintenance 7.1 Care After every use the measuring device must be cleaned, dried and stored in a dry room. 7.2 Maintenance The measuring device must be inspected and calibrated at regular intervals (usually every 12 months) at the manufacturer's facility or by a qualified and authorised body. 7.3 Contact details If you have any questions or problems relating to the measuring device, please contact your local Vogel &...
