YieldPoint’s d-Cable technology provides engineers, technicians, consultants and contractors with a digital instrumented 7-strand cable for geotechnical monitoring. This instrument tracks how the load develops its own length of 7-wire stand cable bolt over time. It allows a reliable assessment of the Factor of Safety against cable rupture. The instrument is applicable to cable bolts, ground anchors, tendons, and tie-backs used in all types of mining and civil projects. It has the potential to help predict the risk of catastrophic structural failure: in fact d-Cable data can enhance many aspects of engineering design, installation quality control, long-term operation assessment, and rehabilitation.

The d-Cable is indistinguishable from a regular cable and deployment simply involves replacing a regular cable with its instrumented equivalent. During cementing/grouting no special procedures need to be followed. The readout head of the d-Cable has the same diameter as the 7-wire strand itself, and therefore grips and a jack can be applied over the readout head if the cable is to be plated. If no face-plate is required the readout head can simply be recessed into the collar of the hole.
