Lifting shackles are important elements of static lifting systems that are used to connect wire ropes and other fittings. They work well for both permanent and non-permanent applications and even in case when the load sliding of the pin cause pin rotation.
Green pin shackles, a necessary shackle type is best-fit to use in confined spaces where its tough strength reduces the physical dimensions of the product while keeping the functionality and working load limit as intact.
There are 2 other categories of the lifting shackles namely chain shackles and bow shackles. While the first one is used with one-leg systems, other one is used for the multi-leg systems.
The chain or D-shape shackles are designed specifically for in-line applied tension and must not be side-loaded. They demand the centre line of the load to coincide with the shackle centre line. Similarly, anchor or bow style shackles can be side loaded and need special focus while carrying out rigging operations.
Round and Webbing Slings- Two Major Lifting Strops
Slings are the best way to lift variety of loads, where the round slings are perfect to lift heavier loads whereas webbing slings seem good for lighter loads. The webbing slings are the lightweight and flexible design with a wide bearing surface and stretchy behaviour for minimized shock loading.
Round slings, on the other hand, are the endless loop of yarns that are covered by a woven tubular jacket. The load-bearing polyester yarns of the round slings contain a protective sleeve to ensure product durability and safety.
The lightweight design of the round slings helps in reducing the fatigue and strain on the riggers. Consistent matched lengths allow better sling load control where an abrasive cover enables no loss of strength. The low stretch feature minimizes sling and load abrasion for low headroom lifts whereas a soft cover won’t scratch the load surface. No sewn edges are allowed to rupture prematurely.
The independent choke yarns termed to choke tightly but can be released swiftly after usage. The high strength to weight ratio allow easy transport.
Lifting shackles are the integral equipment for managing a variety of load securement applications and rigging purposes. Like any other lifting products, managing shackles in the safe environment is essential to carry out the safe results. This is because improper handling might cause severe damage to the place or equipment and fatal injury to the worker.
