MT-LPS-SHK / CUSTOM SHEAR LOAD PINS
Load Sensing Shackles for Lifting
Combine a compatible bow or D-shackle body with a purpose-designed measuring pin and readout. Review the whole assembly for its intended lifting duty, working load limit and pin retention.
Ranges describe a custom family envelope. Diameter and capacity are not freely interchangeable; each combination requires mechanical and calibration review.
JOINT-SPECIFIC DECISION POINTS
Check the contact geometry before the capacity.
- Identify body manufacturer, body size, original pin and marking/traceability.
- State WLL, proof requirements, sling angle, side loading and cyclic duty.
- Define load centering, cable protection and the required assembly documentation.

What the review returns
Assembly compatibility review, WLL basis and agreed proof/calibration documentation.
LOAD-PATH DETAILS
Preserve orientation. Qualify the measurement.
Sensor capacity is not the assembly WLL. Changing a shackle pin can change the approved assembly status. Crosby-body sourcing, lifting approval and proof-test records must be confirmed for the quoted assembly.
A shackle load pin becomes part of a load cell lifting shackle assembly. Confirm the body and pin pairing, working load limit and proof-test scope together.
From the blank pin to a calibrated channel
Request material/heat-treatment identification, dimensional inspection of the bore fit and groove locations, insulation checks, and calibration over the agreed load range using representative support geometry. State proof load, combined error, temperature and traceability requirements in the RFQ.
Define acceptance before manufacture.
The quote should identify the approved drawing, rated force direction, overload limits, calibration method, environmental test scope and output scaling. Certificates or lifting approvals are supplied only when explicitly included and verified for the assembly.
Match outputs & readouts ↗THE FIVE-DIMENSION BRIEF
Your existing pin is the starting point.
Measure D / L / A / B / C or attach a sketch. We review the joint, load cases and interfaces before releasing a drawing or quotation.
- D
- Pin diameter and fit
- L
- Overall loaded length
- A
- Center loading tongue width
- B
- Each outer clevis lug width
- C
- Shear-groove center spacing
L describes the loaded span here. Include the overall end-to-end length, asymmetric lugs, spacers and retention details in your drawing or notes. Five values start the review; they do not fully define a production pin.
