Rigging is an engineering process that uses ropes, chains, slings, hoists, and specialized hardware to lift, maneuver, hold, and position heavy structural loads across diverse industrial environments. In the lifting industry, rigging engineers and safety directors rely on precise load and tension measurements to validate lifting plans, maintain structural balance, and ensure absolute operational safety. Interface sensor technologies, including load cells, load shackles, tension load links, load pins, and wireless telemetry systems (WTS) products, provide the structural integrity and data accuracy required to continuously monitor heavy lifts from initial rig-up through final placement.
Across maritime docks, aerospace assembly bays, construction sites, and theatrical sets, this continuous physical telemetry establishes a reliable safety baseline, preventing equipment degradation and ensuring that heavy-duty rigging components operate well within their certified safe working load (SWL) limits.
Rigging Challenges
The rigging sector operates under zero-tolerance safety mandates, where unverified load weight or improper cable tension can compromise the entire lifting apparatus. Precision force measurement forms the foundation of the safety and operational data loop, converting dynamic pulling forces, suspended weight, and cable tension into immediate, actionable engineering metrics.
Because overloading, uneven weight distribution, or dynamic load spikes can cause catastrophic hardware failure, unexpected rigging collapses, or severe personnel injuries, real-time force measurement is essential. Integrating high-accuracy sensors directly into lifting lines, crane blocks, and mooring points enables rigging engineers to create real-time load maps, set automated overload shut-off limits, and monitor structural strain during complex tandem lifts.
Interface Rigging Solutions
Executing complex rigging requires rugged force sensors that endure outdoor conditions, vibrations, and severe weather. As industries adopt larger modules and automated lifts, precise tension and weight monitoring at key points is crucial. Interface offers cable and wireless Crosby™ Load Shackles, tension links, custom load pins, and LowProfile Load Cells designed to measure tension, compression, and center-of-gravity without adding weight or changing rigging geometry.

Overcoming Cable Management and High-Risk Lifting Challenges
Heavy rigging’s main challenge is maintaining sensor calibration and data transmission in high-risk environments with severe conditions such as wind, saltwater spray, and mechanical shock. Using physical cables on long crane booms or in complex rigging creates hazards such as snagging, wear, and signal loss. To capture these forces safely, low-latency, high-bandwidth wireless systems are needed to provide real-time data on peak loads, tension drops, and sway forces.
Furthermore, loads often don’t distribute force evenly, so sensors must withstand off-axis loads without distortion or drift. Rigging configurations vary, so versatile, quick-connect sensors for standard clevises and shackles are essential. Interface provides rugged, weatherproof load shackles, wireless strain transmitters, and handheld displays that isolate tension, reduce cable clutter, and ensure continuous data during lifts.

Safety in Rigging Operations
Without high-accuracy measurement solutions, heavy rigging relies on static estimates that don’t account for wind, binding, or uneven weight. If engineers can’t verify loads or cable tension during operations, systems risk overloads, tipping, or failure. Accurate force data offers real-time insights for balancing loads, confirming structural integrity, and complying with regulations.
Interface provides rugged sensor tech with high resolution for safe, compliant rigging. Our load shackles, pins, and tension links, known worldwide for low deflection, shock resistance, and wireless reliability, ensure critical load data is instantly available across maritime, construction, aerospace, energy, industrial, and entertainment sectors.
