An Introduction to Slings
The Jaguar blog presents topics for those learning about the new Guyana energy industry, ones relevant to our participation. These posts include ones designed to provide a foundational understanding of energy industry technology and techniques, suitable for all audiences.
This Jaguar blog provides a brief introduction to the 3 main designs of lifting slings, with a YouTube channel link at the end to explore more. The 3 main designs are:
Wire rope slings
Modern material science and manufacturing technology has enabled many variations on these material designs, however, these remain the most commonly found. A summary of each follows.
This is the most versatile kind of sling, typically made from either nylon or polyester fibers. Their properties make them an ideal choice by riggers for many applications, with the following properties:
Lightweight, flexible, easy to handle and manipulate
Easy to store
Ideal for securing and lifting breakable or delicate loads
Not suitable for extreme or rugged conditions
Subject to wearing more quickly than metal based designs
Chain slings are the strongest and most durable type of sling, making them especially suited to heavy-duty construction, mining, and manufacturing operations, with the following properties:
Durable and less subject to damage, useful in construction environments
Can be heavy and difficult to handle, move and store e extremely hot loads
Generally more expensive than other options that may be available
A preferred design for lifts in extremely hot temperatures or securing hot loads
Wire Rope Slings
More durable than synthetic slings and more cost-effective than chain slings, wire rope slings are widely used in many industries. Wire rope slings are made by weaving individual strands of wires around a core, forming a sort of braid, with the following properties.
Extremely strong and resistant to abrasion or cutting
Available in a wide variety of materials, designs, diameters, and configurations….
Which means there are many options that can be tailored to the job
Are susceptible to kinks and twists
For all slings, it is important to follow regulations for inspection, testing and replacement. For riggers, it is critical to perform a quick visible inspection before making a lift. .
