In the rigging world, we are always pushing for “more.” More lift power, more loads, more hours on the rig, etc. This industry is full of diligent, hard workers who strive to get the absolute most out of their crews and their equipment.
One such way that many operators attempt to increase output is by increasing the capacity of each load. More productive loads means jobs get completed faster and more efficiently, and the next project can begin. So, how can we increase the strength and speed of our operation through better lift capacity? Keep reading to hear some ideas from the veterans at Southwest Wire Rope.
As you probably learned during your first training hours, position and angling are immensely important when it comes to lifting. While a straight vertical lift of a single, stable object can be completed at near maximum capacity of your machines, every additional variable you introduce will reduce your lift strength.
The same principles that govern lifting motions of your body apply to lifting loads as well. Lifting a small weight near your torso is much easier than lifting the same weight when your arm is fully extended. The added tension in an extended arm makes the job more difficult. As the boom of your crane extends and becomes more angled, load capacity decreases substantially.
The obvious method to increase your lift capacity is to invest in a larger, stronger crane. Beyond purchasing new power equipment, however, there are various approaches to making the most of your crane.
Changing the type, thickness, or orientation of your slings and chain setup can make a dramatic difference. Increasing the diameter by one-eighth of an inch, for example, can increase your nominal strength by 12 tons.
At Southwest Wire Rope, we’ve spent the past 56 years becoming experts in fabricating the highest quality rigging and lifting products on the market. From rope and chains, to synthetic web and round slings, along with all the hardware you’ll need, we can help you outfit your crane with the best equipment to ensure it’s running at maximum capacity. If you need guidance on which attachments work best for you, we’re here to help.
This brings us to the third, and often most productive, method to increasing lift capacity:
bringing in a rigging consultant. An on-site inspector is vital to staying within the codes of the various regulators, but can also provide valuable advice on which hardware and lifting products might be useful to increase your capacity.
Working alongside a rigging expert who has both practical knowledge on the operation of cranes as well as industry expertise on the outfitting side of the business can pay dividends. Our team will help you create the best lifting solution for your business through our decades of experience backed with rigorous testing. Get in touch with us today to get started.
The professionals at Southwest have been serving the needs of the rigging and lifting industries with an unwavering dedication to quality and excellence for years. If you are in the market for leading rigging equipment, need your rigging tested, or are simply looking for an expert opinion, we can help.

One of the most commonly used and important pieces of equipment in a rigging operation is the sling. Crafted in unlimited lengths and specifications, slings made from synthetic materials such as nylon and polyester are excellent for bearing weight while remaining flexible and maneuverable. At Southwest Wire Rope, fabricating customized synthetic slings is one of our specialities.
Over the past 56 years, Southwest has become one of the most illustrious names in the rigging supply industry through our commitment to quality products. That’s why we take the longevity and condition of our equipment seriously. Synthetic slings, though durable and strong, will not last forever. It’s absolutely vital that you be able to identify the warning signs of the expiration of a sling’s life. Continuing to use a synthetic sling when it is past prime condition endangers not only the productivity of your entire operation, but also the safety of your employees. Keep reading to learn the telltale signs that it’s time to remove a synthetic sling from service.
The most obvious and threatening sign that a sling must be retired is damage. This may manifest through the appearance of holes, tears, or even minor cuts along the length of a sling. While synthetic slings are crafted to be incredibly strong, a small cut can compromise the entire integrity of the sling and eliminate its ability to effectively bear weight.
Damage can also pertain to conditions such as acid or alkaline burns, melting, charring, or weld splattering. Any of these traumas can degrade the fibers of the sling and cause a breakage.
When inspecting the sling for damage, also pay special attention to the fittings and hardware. If the fittings are stretched, nicked, or distorted in any way, the entire sling apparatus should be replaced.
This indicator is more elusive. If the sling identification tag is missing, damaged, or not completely legible, it’s time to retire the sling. With the long list of regulatory requirements from ASME, OSHA, the Department of Labor, and various manufacturer’s, you cannot afford to have even one piece of equipment in degrading condition.
Furthermore, if the ID tag of the sling is smudged or worn, it could indicate that the daily operations of the sling are more risky or damaging than expected.
When it doubt, sub it out. If any conditions arise that might jeopardize the strength or alignment of a sling, it should be replaced with a freshly fabricated one. If a sling becomes twisted or knotted, its load capacity instantly becomes reduced and its function less reliable. Synthetic slings also come with thin covers that protect the underlying fibers from damage; if the stitching of the cover is worn or broken through entirely, the sling is operating dangerously and must be removed from service.
How To Test the Durability of Synthetic Slings
When using slings of various thicknesses and lengths, it can be difficult to keep track of their capabilities. Consult a product specialist at Southwest Wire Rope to confirm the approximate capacity of your sling. Because slings come in an endless variety of shapes and sizes, only an industry professional can give proper guidance.
Booking an on-site rigging inspection is also an excellent way to ensure the safety of your equipment. A Southwest team member can perform a comprehensive gear inspection to make sure every piece of your equipment is functioning properly and up to code. We also have the equipment to perform reliable break testing of various lifting devices, with load test certificates furnished upon completion of every test.

In 1966, a man named Charlie with experience in the shrimping business noticed a strong demand for reliable wire rope and service in Gulf Coast industries. He began buying and stocking material and making assemblies, and soon after, Southwest Wire Rope was born.
56 years later, Southwest has become one of the strongest names in wire rope and chain fabrication, inspection, and testing in the world. Throughout that time, as our company grew and our experiences with it, we have worked alongside and supplied industrial titans. Here are a few key truths about the industry that we have learned along the way.
One of the most important differentiators between Southwest and our competitors is our industry expertise. We have found that being deeply knowledgeable about the materials we provide and their capabilities allows us to provide better service, create lasting partnerships, and craft better solutions for our clients.
We receive requests for quotes or information every week, and many of these inquiries come from individuals in the purchasing department of their company who have very little experience with the wire rope product line. If the recipient of that call at Southwest were not intimately familiar with the industry, they could not guide the potential client to the right solution for their operation. Decades of experience helps us to create thriving rigs and lifting operations across the country.
From the start, Southwest Wire Rope has been driven by integrity, organization, and quality. In 1983, we introduced our identifying trademark to the industry: “Gold Strand” wire rope. Marketed around the world by many wire rope distributors, this rope featuring a tell-tale gold strand represents those guiding values that are woven into every product created by Southwest.
Over the course of the last six decades, our commitment to excellence has helped foster a reputation for industry-leading quality in the wire rope space. Our reputation is one of our most treasured assets, and we fight each day to protect it.
Since our founding, we have been a company of rigging professionals who serve rigging professionals. One thing we know better than most, is that those professionals need professional materials.
This is why we pursue relentless attention to detail in our fabrication and testing. We can provide the highest level of precision on rope lengths that our competitors simply cannot match. We pride ourselves on maintaining an industry-leading product offering with intricate specifications and customization available to all our customers – all made in-house at a single facility.
In this business, every pound, link, strand, and sixteenth of an inch matters, and we approach our work that way.
