In many lifting, pulling, and load-testing operations, knowing the actual load being applied is critical for safety. Assumed weights, calculated sling tensions, or crane charts alone don’t always tell the full story – especially in confined spaces, complex rigging arrangements, or high‑risk environments such as offshore or subsea.

This is where Load Pin Shackles play a key role.

LMS (Load Monitoring Systems) Load Pin Shackles are designed to deliver accurate, real‑time tensile load measurement while functioning as a standard shackle – enabling safer decision‑making during lifting, static loading, pulling, and weighing applications.

What Is a Load Pin Shackle?

A Load Pin Shackle replaces the standard solid shackle pin with a load‑sensing pin that measures tensile force directly through the connection. The pin is instrumented with strain gauges, allowing real‑time load data to be captured without changing the rigging configuration.

LMS Load Pin Shackles combine:

• A high‑strength steel shackle body
• A high‑tensile stainless‑steel load pin
• Integral signal conditioning electronics

Each unit is proof load tested and certified prior to delivery, ensuring accuracy, reliability, and compliance in demanding lifting environments.

Why Use a Load Pin Shackle?

Load Pin Shackles are often chosen when:

• Headroom is limited
• Loads need to be monitored live
• A standard shackle already exists in the load path
• Additional lifting accessories or load links would make the rig too tall or complex

By measuring load directly at the connection point, operators gain clear visibility of actual forces – helping prevent overloads, incorrect assumptions, and unsafe lifting conditions.

Key Safety & Performance Benefits

✅ Ideal for Low‑Headroom Applications
Because the load monitoring function is built into the shackle pin itself, no additional height is added to the rig. This makes Load Pin Shackles ideal for confined or restricted lifting environments where space is critical.

✅ Accurate, Certifiable Load Measurement
LMS Load Pin Shackles are available in capacities from 2Te to 2000Te, with a 5:1 safety factor. Each unit is load tested and supplied with certification to ensure dependable, traceable measurements.

✅ Real‑Time Wireless Monitoring
With integral signal conditioning, load data is stable and reliable. Up to 12 Load Pin Shackles can be linked to a single wireless handset, allowing operators to monitor individual or combined loads from a safe distance.

✅ Robust Construction for Harsh Environments
The combination of stainless‑steel load pins and high‑strength steel bodies delivers durability and corrosion resistance – suitable for marine, onshore, offshore, and subsea applications.

✅ Adaptable and Customisable
Subsea variants and special designs are available, allowing LMS to tailor Load Pin Shackles to specific project requirements, including specialist dimensions or outputs.

Typical Applications

LMS Load Pin Shackles are widely used across:

• Offshore and subsea lifting
• Marine and port operations
• Static and dynamic load testing
• Construction and industrial lifting
• Mooring and anchor systems
• Pulling and tensioning operations

In each case, the ability to see the live load adds a critical layer of safety and control.

What’s Included?

Each LMS Load Pin Shackle is supplied as a complete system, including:

• Fully assembled Load Pin Shackle
• Wireless handheld display
• Certified load test documentation
• Spare batteries (UK shipments)
• Options for subsea and custom variants

Summary

LMS Load Pin Shackles provide a simple, space‑efficient way to measure load accurately where it matters most – directly in the lifting connection. With low‑headroom suitability, wireless monitoring, high-capacity options up to 2000Te, and certified performance, they are a trusted solution for safer lifting, pulling, and load‑testing operations across multiple industries.
