Rugged Precision in Motion: ADI CONTROLS ALP-751 Clevis Load Pin Load Cell

In heavy lifting, material handling, and structural monitoring systems, direct force measurement is critical for both safety and control.
Unlike traditional load cells that measure compression or tension indirectly, load pins provide in-situ force sensing right at the mechanical joint, where the load actually acts.

At ADI CONTROLS, we engineer sensors that combine mechanical robustness with measurement accuracy.
Our ALP-751 Crane Load Cell is specifically designed for this purpose, to replace existing clevis pin or hinge pins while accurately measuring the load acting through the structure.

What is a Clevis Pin Load Cell?

A clevis load pin (or shackle pin load cell) is a custom-machined stainless-steel pin that contains strain gauges installed in its cross-section.
When a load is applied through the pin, the internal strain gauges measure the resulting shear forces and convert them into an electrical signal proportional to the applied load.

In simple terms, the ALP-751 converts a standard mechanical pin into a high-precision, load-sensing element, making it ideal for use in lifting, hoisting, and overload protection systems.

Engineering Design of the ADI CONTROLS ALP-751

The ALP-751 is engineered for harsh industrial environments, providing reliable, real-time load monitoring without altering the mechanical structure.

Key Design Features

  • Direct Force Measurement: Installed directly at the load path for accurate readings.
  • Custom Machined Construction: Designed to fit customer-specific clevis or shackle dimensions.
  • High Strength Material: Made from stainless steel for corrosion resistance and long service life.
  • Hermetically Sealed Gauges: Protected from moisture, dust, and mechanical damage.
  • Dual Shear Sensing Zones: Ensures uniform stress measurement and high linearity.
  • Environmental Protection: IP67/IP68 sealing for outdoor and marine applications.
  • Integrated Cable or Connector Output: A rugged cable gland or connector interface designed for industrial use.
  • Compatible Electronics: Seamless integration with ADI Controllers (LC-50K, LC-55, etc.) for full system monitoring.

Applications of the ALP-751 Clevis Load Pin Load Cell

  • The ADI ALP-751 is designed for environments where traditional load cells cannot be easily fitted, such as:
  • Crane and Hoist Load Monitoring
  • Winch and Pulley Systems
  • Lifting Equipment Safety Systems
  • Marine and Offshore Mooring Lines
  • Hydraulic Cylinder Load Measurement
  • Structural Load Testing
  • Aerospace and Defence Test Rigs

  • Because it replaces existing mechanical pins, it’s ideal for retrofit applications where installation space is limited or modifications are impractical.
