Heavy‑Lifting & Cranes:

The Backbone of Industry

Don’t let the invisible stop the unstoppable.

Container terminals, steelworks, and offshore platforms operate on a simple rule: downtime is not an option. In these high-stakes environments, cranes lift hundreds of tonnes around the clock, placing immense stress on their wire ropes.

Salt spray, abrasive sheaves, and sudden shock loads create a dangerous enemy: internal fatigue. While the rope may look perfect on the outside, hidden cracks can develop deep within the core. RopeWatcher brings ISO 4309 compliance into the real world, giving you the power to see inside the rope. We help you prevent catastrophic failures, protect your heavy assets, and ensure that your operations never stop unexpectedly.

ISO 4309:2017 – The Standard for Internal Integrity

The global code “Care and Maintenance of Steel Wire Ropes” is clear: assessing the external surface is no longer enough. The standard explicitly requires the evaluation of the internal state of the rope to identify hidden deterioration.

For this critical task, Magnetic-Inductive Testing (MRT) is the only admitted method capable of providing a non-destructive, reliable assessment of the core. RopeWatcher ensures you meet this requirement fully, using the precise technology mandated by the standard to determine discard criteria with absolute certainty.

AMC Instruments — the state of the art for crane‑rope MRT

AMC has translated these normative requirements into field‑proven technology that is now trusted by dozens of lifting companies worldwide—from port‑crane service providers in Northern Europe to offshore operators in the Middle East.

Dual‑signal diagnostics (LF + LMA)

Every scan delivers both the Localized Fault trace, which pinpoints individual wire breaks, and the Loss of Metallic Area trend, which quantifies corrosion and wear—exactly the parameters referenced in ISO 4309.

Certified sensitivity

Our sensor heads meet the accuracy and magnetisation benchmarks laid down in EN 12927, proving a signal‑to‑noise ratio > 2 during type‑approval testing.

Built for harsh environments

Sealed electronics (IP 66), stainless‑steel frames and an operating window of –20 °C to +50 °C ensure long‑term reliability on ship decks, jack‑ups and dusty mill bays.

Battery autonomy & quick deployment

Internal power supplies keep the system running for a full shift; the clamp‑on head is fitted in minutes without altering reeving or taking the crane out of service.

Combining full regulatory compliance, advanced dual signal diagnostics and mountain proof robustness, AMC solutions have become the global reference for ropeway operators who demand continuous, accurate and regulation ready control of their ropes.

What this means for your operation

Normative alignment

inspections fulfil ISO 4309’s requirement to detect internal damage, satisfying auditors and insurers.

Reduced downtime and cost

a single pass of the hook block provides a comprehensive health check, minimising production stops and extending rope life.

Objective, traceable data

trend curves show exactly how fast a defect is growing, so rope changes are scheduled just‑in‑time, not months too early.

Global support network

AMC’s training partners can certify your technicians to ISO 9712 and help interpret LF/LMA traces wherever your cranes operate.

In short, AMC’s MRT solutions deliver the speed, sensitivity and regulatory compliance that heavy‑lifting operations demand—making them the reference point for wire‑rope integrity in the modern crane industry.
