One of the biggest benefits of a nylon rigging setup is the diversity and range of its use. This material is designed for industrial sling applications and lifting heavy loads by crane or pulley, but it is also gentle on your equipment and inventory that needs to be lifted. The result is widespread use of nylon slings for rigging in the aerospace, mining, transportation, and energy industries that all work with heavy, but delicate, materials.
The many options for hitches with a nylon rigging is also a plus for users. Across industries, the varied shapes and sizes of the flexible nylon material is a bonus. The following is a list of the basic hitches possible with nylon rigging but even more complicated hitches are possible.
Why Your Sling Hitch Matters
Wondering why the shape and style of your sling hitch is important? It actually affects both the maximum weight and shape of what you can lift with the sling. Different slings have different weight capacities and are also better at balancing different sizes and shapes of loads. Matching the load you want to lift or lower to the right style of nylon sling shape is important for safety and effectiveness of the equipment. It is also essential to protect your nylon slings for rigging from damage or extraneous wear and tear.
A Straightforward Approach: The Vertical Sling
The most basic way to attach your nylon sling to a crane or other equipment is through a vertical hitch. In this arrangement, one end of the sling is attached to the hook or other master link on the crane, then the other end is attached to the load. Thus, it creates a vertical line from the rigging to the load. This is the only type of hitch where the maximum lifting capacity of the sling can be utilized, as in other arrangements the sling is attached twice to the master link.
Therefore, a vertical hitch is appropriate when lifting a heavy load with a specified center of gravity and weight. If the weight of the load isn’t evenly distributed or carefully maintained as the user lifts or lowers the load, then it can cause the entire piece of equipment to swing and sway. Both motions put extra pressure on the rigging and can cause damage to the sling.
Lifting Lighter, But Complicated Loads
The vertical hitch has some drawbacks for users in terms of stability and weight management. These issues make it impossible to use a vertical hitch when weight is likely to shift easily during the lifting process or when the object to be lifted is a complicated shape or size. In these instances, many users employ a choker hitch.
The choker hitch is constructed from a single nylon sling, but instead of attaching to the crane or equipment once and the load once, the sling is attached to the master link, threaded through or around the object, and then passed back through the original length of the sling to form a knot or choke around the object. This increases the stability of the the sling, but the single choke point decreases the maximum manageable weight of the sling components. The result is a more stable sling, which can lift bars, rods, and other awkward objects, but can, simultaneously, only lift 75% of the sling’s original rated capacity.
Working Towards the Right Lifting Angle
When working with rigging, weight management and control are essential. This information forms the defining factor behind why and how a specific sling is arranged, and, sometimes, neither a vertical or choke hitch will cut it to lift an uneven or bulky load. In these instances, single nylon slings for rigging can still be utilized if arranged in a basket hitch.
There are multiple types of basket hitches, and choosing the right one is dependent on evenly distributing the load’s weight on all sides of the sling and then keeping that weight even as the load is lifted or lowered. To steady or evenly distribute a load, the basket hitch can be arranged at various angles, but the wider the angle between the nylon sling and the master link, the greater the decrease in allowed weight for that sling.
For example, a sling set at a 80 degree angle to the master link can handle 98.5% of the weight of the sling set at a vertical hitch, while a sling at 60 degree to the master link can only lift 86.6% of the weight of the sling set at a vertical hitch.
Buying a Nylon Sling for Any Hitch
Luckily, as your needs for a nylon sling change and alter over time and with the type of materials you need to move, the nylon material will adapt. A single nylon sling can be arranged in a vertical, choke, or basket hitch at any time, and the material is light enough for users to easily detach, move, and rearrange the sling as needed.
