Load Cell Measuring Pins & Shackle Pins

Custom Designs and Variations

All load measurement pins are constructed in high strength 17-4PH stainless steel. (AISI 630) Standard IP 68 sealing (total dust ingress protection and long term immersion in water). Standard 1 mv/v output. 300% safe overload. 600% ultimate. The nominal safety factor is 7:1, we will advise on specific designs.

Optional: Integral or external 4 – 20 mA, or telemetry wireless transmitter.

Applications: Up to 500 Tonnes Crane lifting weight and overload readings Cargo and material handling reading Vehicle drawbar force Rigging and lifting Conveyor monitoring (weight) Dynamometers Axle Shaft or Pin replacement to record weight and force Models for general critical weighing and monitoring applications The radio linked shackle pin does not require an external aerial

Load Pin Locking Systems

A load measuring pin needs to be securely locked into position in order to fix its orientation with respect to its associated assembly. This needs to be fixed, both in the axial and rotation modes, to ensure that accurate and repeatable results are obtained from the system. A standard load pin is designed to sense the force in one direction only. A force at right angles to that force will produce a zero output from the sensor.

• Load pin orientation: Always keeper slot to top provides correct polarity.
• Ensure center section is not mechanically shunted across the waist grooves.
• No friction between center section and side plates.
• There should be no axial forces applied to the load pin. The keeper plate has clearance in slot and does not
         apply pressure to the load pin at any time, especially under load.
• The 630 stainless steel load pin is normally heat treated to 44-52HRC.
