Shackle is a hook tool between sling eyes and certain object hooks made of mild steel, carbon steel, alloy steel and Stainless steel 304 & 316. The function of this shaft is to connect or attach slings to lifting objects. Shackles are usually used to lift items, basketballs, beams, machines, and other lifting objects that are heavy, so you have to use slings and shackles as lifting aids.
Basically a shackle is a tool for lifting large and heavy items (rigging), as a link between the sling and the object to be lifted.
Specifically, the Shackle is a tool for connecting slings, be it chains, wire ropes, or webbing, which are commonly used in lifting, towing or lashing applications. It can also be used to connect chains in construction applications, fences and decorations. This connecting tool is made of steel. The general shape is curved like the letter U, where at the end there is a hole for installing the lock.
Shackle Types based on Shape and Type
Based on the shape of the type, shackle can be classified into 2 types, namely:
Shackle Dee
The shape resembles the letter D. Suitable for lifting goods using a chain or chain sling. With a shape that resembles the letter D, the chain can be properly installed in the seal hole, friction between the chain and the seal can also be minimized. Therefore the chain can be tighter and safer when lifting goods.
Shackle Omega
As the name suggests, this type is shaped like an omega symbol or a horseshoe. Its general use is usually for lifting or towing using wire ropes, for example wire rope slings. This type of hook hole is designed to be larger than the Dee type.
This is to adjust the size of the wire rope which has a larger diameter compared to the chain. In one seal can be installed 2 wire rope slings. Its horseshoe-like shape allows the wire rope sling to be properly attached to the seal hole, minimizing the friction between the wire rope sling and the seal. Therefore wire rope slings can be tighter and safer when lifting goods.
Below is a daily inspection checklist for shackles that you can regularly inspect for your sealing tools.
