SA Shackles

The SA shackle is a rigging component used to secure loads during loading and unloading operations. SA stands for “Anchor Shackle”. The design is simple to use, reliable and durable. Product quality is determined by the materials of manufacture. The types and specifications of shackles are defined by OST 5.2312-79.

Design and operation

The SA shackle is used to secure pipelines with an outer diameter matching the inner diameter of the shackle. The design is a metal U-shaped element with holes at the ends for inserting a fastening bolt. It is a straight shackle that can be supplemented with a cotter-pin lock.

Operation is permitted under conditions where the wire rope is clamped and there is room to accommodate all the components. The SA 320 type shackle ensures secure load fixation and prevents damage during transport. Shackle variants can withstand loads of up to 85 tons.

Material

SA shackles are manufactured from high-strength steel, then undergo hot-dip galvanizing, which increases strength and resistance to external effects. This ensures reliable fixation and connection of flexible elements to one another.

How to choose

The choice of shackle depends on the loads the structure will be subjected to during operation, the dimensions of the space between elements, and the type of product being moved. It is important to correctly calculate the load limit so that the chain does not break during lifting or lowering.

For safe operation, the shackle’s diameter and other specifications must be selected correctly — otherwise the risk of injury to personnel increases. Take into account the nature of the application environment: for example, maritime and shipbuilding applications require models with increased corrosion resistance. The shackle’s diameter and the wire rope’s strength also affect operational safety.
