Load Monitoring
Rope Mounted
Load Cell
Measure the live load on any overhead crane hoist rope with ±1% full-scale accuracy. Engineered for demanding industrial environments, CE certified, and designed to connect directly to IntelliKran PLCs with no additional signal conditioning.

Features
Built for the Realities of Industrial Crane Operation
Every feature has been selected around one goal: giving crane operators and engineers reliable, actionable load data — every lift, every shift.
±1% Full-Scale Accuracy
Delivers consistent, repeatable readings across the rated capacity range — accurate enough to drive real-time overload alarms and load logging.
Rated to 60 °C Ambient
Engineered for the harsh thermal environments found in steel mills, foundries, and outdoor port cranes, where summer ambient temperatures regularly exceed 50 °C.
CE Certified
Complies with applicable EU Machinery and Low Voltage Directives, simplifying regulatory approval for new crane installations and retrofits.
Plug-and-Play PLC Integration
Outputs a standard 4–20 mA or RS-485 Modbus RTU signal, connecting directly to any IntelliKran PLC analogue or serial input without additional signal conditioning.
Overload & Two-Block Protection
Real-time load signal feeds the IntelliKran safety logic, enabling configurable overload trips (e.g. 110% SWL) and early-warning thresholds well before the mechanical limit.
Low Power Consumption
Draws fewer than 30 mA at 24 VDC, compatible with crane panel supplies and battery-backed UPS systems with no derating.
Load History & Trending
When paired with the IntelliKran PLC, every lift is time-stamped and logged. Operators and managers review load curves, peak loads, and cycle counts on the web dashboard.
High Durability Construction
Forged alloy-steel body with IP67-rated stainless cable glands withstands rope vibration, shock loading, wash-down, and continuous outdoor exposure.
How It Works
From Rope Tension to Cloud Dashboard in Milliseconds
01
Rope Deflection Sensing
The load cell body is clamped onto the hoist rope between two fixed sheaves. As rope tension rises with the lifted load, the cell deflects and its internal strain gauges register the change.
02
Signal Transmission
A 4–20 mA or Modbus RTU signal is continuously transmitted to the IntelliKran PLC analogue or serial input. Cable screening and twisted-pair wiring reject electrical noise from VFDs and contactors.
03
PLC Processing & Action
The PLC converts the signal to engineering units, logs every reading with a timestamp, triggers overload alarms when the threshold is exceeded, and pushes data to the IntelliKran cloud dashboard in real time.
Applications
Where It Is Used
Overhead crane SWL monitoring and overload prevention
Hoist rope tension measurement for load-sharing multi-hoist systems
Lift-by-lift load logging for predictive maintenance programmes
Port and shipyard gantry cranes with high-cycle duty requirements
Steel mill ladle and stripper crane monitoring
Oil & gas offshore crane compliance logging
Retrofit of older cranes lacking built-in weighing capability
Proof-load testing and periodic safe-load indicator calibration checks

Designed Around Crane Safety Standards
The load cell is designed to complement existing mechanical safe-load indicators (SLI) and is not intended as a standalone safety device. When integrated with the IntelliKran PLC, the system provides a redundant electronic load check, real-time operator alerts on the cab display and web dashboard, audible/visual alarm relay outputs, and a tamper-evident digital load log — all supporting compliance with FEM, ISO 4301, ASME B30, and EN 13001 crane design standards.
