О себеHeavy loads pose a great challenge for manual workers and can take loads of time to move around without the help of loading equipment. Textile slings are designed to make this work easier and they have been largely effective on this end. They are hooked to hoists and provide handling capabilities for heavy loads. They are used extensively on construction sites especially when the building under construction is bound to have at least a couple of floors.
Colour code of lifting slings
The colour coding system is part of the numerous regulations that the lifting operations industry has put in place to manage the use of different equipment. The regulations require that suitable marks are placed on the lifting equipment for safety purposes. One should know the safe working load limit to reduce the risk of injury they are exposed to. The sling cannot lift any load that is more than the working load limit. Different colour codes are used to indicate the limits of lifting slings.
Do textile slings expire?
Time does not single-handedly affect the durability of textile slings. Weather, use of slings as well as environmental conditions all play an active role in determining how long the slings will last. Storage conditions also influence the overall strength of the string and manufacturers to encourage consumers to provide optimum storage conditions.
DIFFERENT TYPES OF WEBBING SLINGS
Webbing slings are flat belts, usually manufactured to duplex level featuring double layers for extra safety. These slings are one of the most essential and common lifting accessories. Eye and eye, and endless webbing slings are the most popular and can be easily found in the market. These two types of webbing slings can assist your lifting project and can be used with many different configurations as explained below.
Eye and Eye webbing slings
This type of webbing sling has an eye shape on each of its end points, also, its flexible and light weight making this sling versatile, and for many the preferred sling. Eye and eye slings can also protect delicate loads and minimise the risk of damage, dents or scratches while the lifting action is being performed. They are also very easy to use with a choker, basket, or vertical configurations.
Endless web slings can be used in all three types of sling hitches. The sling can be rotated throughout its service life to minimise wear and avoid repetitive use damage.
All webbing slings can be found in two materials which can be nylon or polyester. Both of these materials will have the same strength and capacity to lift your load, however, you need to consider your options depending on the application as in some circumstances the sling will be exposed to acids or high/low temperatures.
Nylon webbing slings are able to assist when there is grease and oil present and this material has a very good resistance to certain chemicals, however acids, bleaching agents and temperatures over 194OF will drastically affect this type of sling. ;
Introduction to Round Slings
Round slings are an all-purpose lifting sling enabling a strong and non-damaging lift of a load. They are extremely light weight and flexible in multiple directions, allowing easy and quick manipulation even when fragile loads are being lifted. Round slings are a continuous loop made from polyester yarn encased in a sleeve of polyester fabric. The sleeve is constructed, so that it protects the internal rows of yarn filament and keeps them in a parallel formation at all times. The yarn fibre (core) is free to spread out where the round sling is in contact with its load. This provides a broad support, which cushions the load against damage and reduces slipping. The low stretch characteristics of the polyester yarn also prevent ‘load bounce’ when lifting.
How to Use Ratchet Cargo Straps: Ultimate Step-by-Step Guide with Straps Pictures
Ratchet straps are cargo tie-down straps made of polyester webbing. They are run through a buckle that lets you loosen and tighten the strap, so you can lengthen the strap until you can pull it across your entire load, then tighten the strap until there’s enough tension to secure the load. Occasionally, we are asked how to use ratchet straps and what ratchet tie-down straps are for.
Ratchet cargo straps can tie down a load by securing it to the floor of a flatbed truck. They can also be used to tie down and secure a piece of cargo to the sides of the interior of an enclosed trailer. It can connect to anchor points in the side of a flatbed truck, like D-rings, and can also latch onto anchor points on the floor of the truck bed for easy tightening!
If you take good care of your ratchets and cargo straps, a ratchet strap should last you between 2 and 4 years. Never use a ratchet strap if there’s clear abrasive wear and tear, cuts, or any hardware deformation in the ratchet itself. Inspect your straps and ratchets after every job, and replace your trucking accessories the moment you notice damages!
What is a Cam Buckle Strap?
A Cam Buckle Strap is one of the more unique types of tie-down straps as they don’t use a mechanism to secure cargo with such as a Ratchet Strap that uses a Ratchet to tighten the cargo. Cam Buckle Straps are tightened by using hand strength and can only be tightened as much as your hand force can physically tighten. Some of the major benefits of using a strap like a Cam Buckle is the fact that sensitive surfaces such as antiques, lightweight cargo with sensitive edges, or brittle valuables are rarely ever damaged when tightening these straps.
Cam Buckle Straps utilize a Cam Buckle with a clip that is similar to a belt where once the tie-down webbing is pulled through and the cam buckle is released the strap is secured into place. This is the ideal cargo securement for lighter weight cargo securement or fragile cargo. Ideally, Cam Buckles are one of the most commonly used straps for movers who are dealing with customers who could potentially lose repeat customers if the customer’s valuables are damaged beyond repair.
One of the very few downsides of using Cam Buckle Straps is unlike Ratchet Straps or Winch Straps it isn’t exactly ideal for the heaviest of cargo weights such as professional trucking flatbeds. This is one of the downsides that you want to make sure are tighter than the force of webbing that you can pull through on cargo that could easily weigh more than several thousand pounds or more.
How Much Weight can Cam Buckle Straps Secure?
On average if you have cargo above 750 pounds you should instantly consider using a Ratchet Strap or a Winch Strap if you are using a commercial flatbed trailer. Ratchet Straps and Winch Straps are designed for the heaviest duty cargo securement, whereas Cam Buckles are designed for lightweight to mediumweight cargo.
The one main way to tell if you will be safe or not for your load is by looking at the assembly working load limit for each of the straps that you intend on using for your cargo securement needs. If the assembly working load limit is way too little for the weight of your cargo you will want to look for another strap. Although you should always use AT LEAST FOUR TIE DOWN STRAPS when you are securing cargo they may still not be strong enough for your cargo. One important thing to remember when securing cargo is to know that the straps are only as strong as the strap’s weakest link or part of the strap.
What is Webbing?
Webbing is a woven fabric that is distinguishable by its various material compositions, strength variations and widths. The webbing process essentially involves yarns that are woven via looms to create strips. While it is generally comparable to rope for its harnessing function, webbing is an extremely versatile component used in an array of industry applications, ranging from military apparel to automotive parts. Typically, webbing is fabricated in solid or tubular form, with each type having different applications and functions. While ropes are typically thick in texture, webbing is produced in extremely lightweight parts. The primary materials used in the production of webbing include variations of polyester, nylon, and polypropylene. Cotton webbing is also available and is commonly used in commercial applications, including clothing apparel. Webbing is also customizable in a series of colors, designs and prints, and manufacturers can fabricate reflective webbing for safety applications.
