Early Warning Devices

Smart & Effective Strata Monitoring

RockTale

RockTale is an advanced early warning device designed to detect roof instability in underground mines. Featuring dual LED indicators (blue & red), reflective pistons, and audible alerts, it provides real-time monitoring of strata movement as small as 3mm.

Dustproof, waterproof, and intrinsically safe, RockTale is easy to install, fail-safe, and eliminates human error. Customizable in length and built for all mining conditions, it ensures 24/7 dependable monitoring to enhance mine safety.

Strata Displacement Monitor

RockTale20

RockTale20 is a new-generation rock monitoring device — bigger, brighter, more visible, and equipped with added RF capabilities. A green light indicates successful commissioning and an actively monitoring device. Once inserted, RockTale20 monitors the roof strata 24/7, providing continuous oversight and safety.

In the event of separation in the strata, the anchors trigger a flashing blue or red light. Simultaneously, a radio frequency signal is generated, delivering real-time information to the control room or a smart device. This revolutionary device serves as an excellent early warning system, generating crucial data and saving lives.

Strata Displacement Monitor

RockSpy

RockSpy is a simple and effective early warning system for monitoring strata displacement. Anchored in competent rock, it provides a two-stage visual alert of movement. 

First trigger (blue piston) activates with 1-3mm displacement, while the second trigger (red piston) engages with further movement (up to 20mm). This allows for quick, easy identification of potential roof or hanging wall separation, enhancing mine safety.

Blastproof

RockSpy Eco

RockSpy Eco delivers the same innovative monitoring capabilities as RockSpy, with the added benefit of being blast-proof. Designed for areas closer to blasting zones, it withstands harsh mining conditions while maintaining high visibility and accuracy.

With its rugged construction and two-trigger system, RockSpy Eco provides clear early warnings of strata movement. It offers easy installation, durability, and a low-cost solution for increasing safety coverage in high-risk areas.
