The RTM can be used in applications where accurate measurement in preloaded wire ropes is required. Such applications can be stay ropes, suspension ropes, catenary ropes, etc. The RTM is applied direct to the rope and the measured tension value is presented digitally.

RANGE OF APPLICATION

The RTM (Rope Tension Meter) was designed to swiftly and accurately measure the tension in fixed or stationary ropes or cables, i.e., guy wires for masts and/or towers or other guyed constructions.

The RTM will also be very useful in determining the tension in overhead suspension ropes for railways catenarys.

The RTM can be used to measure tension forces up to 44000 lb. (20 metric tons) and for wire rope with a diameter of up to 1-33/64″ (38 mm).

Thanks to the use of microprocessor technology the RTM can be calibrated on up to 10 different wire rope dimensions/types. The digital readout display will clearly show the tension of the wire rope selected. No calibration tables are required.

FUNCTION

The RTM is very simple and handy to use. Simply hold and “clip” it to the rope to be tested and use the large hand screw to deflect the rope to a fixed angle.

The resultant force will then affect the load cell and measure the tension in the wire rope. The resultant signal is then digitally processed and displayed in a graduation selected and preprogrammed.

The RTM can be graduated in kN, klbs, or in tons.

Safety

The RTM is a delicate testing instrument for swift, handy and accurate testing of pretensioned stationary ropes.

Thanks to the design of the instrument it can temporarily be overloaded up to 100% of its nominal capacity without affecting the accuracy of the instrument.

Thanks to tempered outer rope supports and centre clamping jaw will give the instrument a long service life for accurate measurements.

The RTM is delivered in a robust and light weight transport case (760 x 400 x 170 mm) for easy handling and protection of instrument.
