CTM-QC / Tower & guy wire

Handheld Quick-Clamp Cable Tension Meters

Check stationary, tensioned guy wires without removing a cable end. Specify rope construction and the actual working load before selecting a quick-clamp meter.

Handheld lever conceptual measurement arrangement — Measurement concept only. Released product photos, drawings and configuration data are supplied with an agreed offer.

START WITH YOUR ROPE

Cable diameter × tension capacity

Planning envelopes across each family. A single model does not cover every diameter and load combination. Confirm the exact rope profile, range and calibrated accuracy in your quotation.

Model family	Supported cable diameter	Tension capacity envelope	Accuracy	Operation mode
CTM-QC	3–28 mm / 0.118–1.102 in	10–100 kN / 2,248–22,481 lbf / 1,020–10,197 kgf	Target ±1.5–2% FS; subject to rope-specific validation	Handheld lever

MEASUREMENT WORKFLOW

Handheld lever: define the installation first

Select the verified rope profile, fit all contact points to a stationary cable, engage the lever as instructed, then record stabilized readings. Follow the instrument manual for repeat positions and clearance.

A diameter match alone does not establish calibration. Strand construction, coating and stiffness can change the indication.

Before specifying CTM-QC

Will one calibration cover all rope sizes?

No. Different diameters and constructions require appropriate profiles and contact geometry. Provide the complete cable list and request a calibration scope for each combination.

How do we confirm the quoted accuracy?

Agree the range, error definition, reference instrument, rope condition, load points and acceptance limits. A planning target is not a calibration certificate.

Can you review a replacement instrument?

Send the current model, rope profiles, loads, accessories and required data outputs. CTM is independent of the brands mentioned on this site.

GET THE CONFIGURATION RIGHT

Send the rope size. Define the load.

We will review cable construction, measurement range, access and output requirements with your RFQ.
