Load Pin for Crane Overload Protection

Direct force sensing in lifting hardware

Our LP-200 series load pins are designed to replace existing clevis pins in gantry cranes and hoists. The integrated full-bridge strain gauge provides real-time load data without modifying the mechanical structure. Rated from 5 to 500 tonnes, each pin is heat-treated and coated for corrosion resistance. The output signal is compatible with most PLC and display systems.

Trusted by industry

Field-proven force measurement

Our load cells and pins are used daily in Indian ports, steel plants, and heavy engineering workshops. Here is what engineers and safety officers say about the reliability of Fdym transducers.

We retrofitted the LP-200 load pin on three 50-tonne gantry cranes at Paradip port. The calibration curve matched the factory certificate within 0.03%. No drift after six months of monsoon exposure.

Javed Chitranjan Bala Chief Engineer, Paradip Port Trust

The HR-500 load cell replaced a competitor unit that failed every quarter. After one year of continuous use in a sinter plant, the zero balance shifted by only 0.01% of rated output. That is the kind of stability we need.

We use the DFS-100 dynamic sensor for drop-test validation of crane hooks. The 10 kHz bandwidth captures the full impact transient. The 5-point dynamic calibration gave us confidence in the data for certification.

Feroz Chopra Testing Manager, L&T Heavy Engineering

Fdym provided a complete overload protection system for our 200-tonne ship-to-shore crane. The load pins integrated seamlessly with the existing PLC. The 10-point calibration certificate was accepted by the Indian Register of Shipping without queries.
