Tri-Plates: Engineered Load Equalisation for Multi-Leg Lifting
Balanced load distribution in complex lifts
Tri-Plates provide a central connection point that promotes even load sharing across multiple slings, reducing stress concentrations on shackles, slings, and load points during multi-leg lifts.
Versatile for rigging, mooring & heavy lifting
Designed for rigging, lifting, towing, and mooring applications, Tri-Plates offer a compact and effective solution where conventional spreader systems may not be suitable.
Engineered for reliability and traceability
Manufactured with full material traceability and proof tested in-house, Tri-Plates deliver confidence in demanding marine, offshore, construction, and heavy lifting environments globally.
Multisec Tri-Plates

Multisec Tri-Plates (also commonly referred to as Triangle Plates, Delta Plates, or Monkey Plates) are engineered rigging components designed to provide efficient load distribution and controlled sling management in complex lifting arrangements. By creating a central connection point for multiple slings, Tri-Plates help reduce congestion at the lifting interface while promoting stable and balanced load transfer across the lift.
Key benefits include:
Centralised load equalisation for multi-leg lifting arrangements
Improved sling management and reduced bunching at connection points
Compact alternative where spreader beams are impractical
Suitable for demanding marine, offshore, construction, and heavy lifting applications
Manufactured with full material traceability and proof tested in-house, Multisec Tri-Plates provide a reliable and adaptable solution for critical lifting operations.
Typical Applications
Tri-Plates are widely used across industries where multiple slings converge and balanced load distribution is essential.

Construction & Civil Engineering
Used for rigging structural components and multi-leg lifts where load stability and sling management are priorities.
Offshore & Marine
Employed in subsea lifting, vessel mooring and towing setups to ensure even load transfer and reduced sling interference.
Oil & Gas Projects
Suit lifting and placement of heavy equipment in offshore and onshore installations where safety and reliability are paramount.
Industrial Heavy Lifting
Used in plant installation, maintenance, and bespoke lifting arrangements requiring precise force distribution.
Custom Project Rigging
Tri-Plates can be tailored to meet specific project requirements where standard lifting solutions are not adequate.

Frequently Asked Questions (FAQ)
Tri-Plates are rigging accessories that provide a central connection point for multiple sling legs, promoting even load distribution and reducing sling interference. They are also known as Triangle Plates, Delta Plates, or Monkey Plates.
Tri-Plates are used in construction, rigging, marine/mooring, offshore, oil & gas, and heavy industrial lifting to manage complex, multi-leg loads safely.
By centralising sling connections and promoting balanced force transfer, Tri-Plates help reduce sling bunching and uneven load paths, increasing overall lift stability.
Yes. Multisec engineering can design bespoke Tri-Plates to meet specific project requirements that standard configurations cannot address.
Lifting points are positioned during configuration to suit the module geometry and structural pick-up points. The final arrangement is confirmed during the engineering and quotation stage.
Typically: load weight, module footprint and overall dimensions, lifting point locations, intended lifting method, and any headroom or site constraints. Providing drawings or a lifting plan can speed up the quotation process.
