Hoisting and rigging is an important skill for many industries, from construction to manufacturing. With this beginners guide, you will learn the fundamentals of hoisting and rigging, including basic rules, methods, tips and more. Get started today for a better understanding of these tasks!
Determine the Load’s Weight and Balance.
Before lifting any load, it is important to first determine the weight and balance. Improper weight distribution can increase the risk of an accident or injury, as well as damage to equipment. Make sure to always calculate the center of gravity and secure evenly balanced rigging points before attempting to lift a load.
Use appropriate hoisting devices such as chains, straps, and slings with certified ratings to handle specific weights. Examine every component before you start hoisting and make sure they are strong enough for your task.
Be Familiar with the Types of Hitches Used for Rigging and Lifting Purposes.
There are various types of hitches used in rigging and lifting, such as the eye sling, basket hitch, vertical choker, horizontal choke, and bridle hitch. Each of these has its own functionality when it comes to hoisting loads.
The eye sling is a single leg sling that attaches to an object with an eye or loop; the basket hitch can be configured in multiple directions for unique shapes; the vertical choker functions like a noose around the load; the horizontal choke provides stability when lifted at an angle; and finally, a bridle hitch is two or more legs tied together for maximum security.
Observe the Angle-of-Pull and the Relative Placement of Equipment.
In order to safely and effectively employ hoisting and rigging techniques, it is essential to observe the angle-of-pull and the relative placement of equipment. This is to make sure that physical stress on the hardware and the load being lifted is kept at a minimum. Pay particular attention to where attachments, such as hooks or shackles, are placed in relation to loads.
Always ensure that they are vertically aligned to prevent torsional forces on the hardware, reduce stress on the links and protect against undesirable contact with proximal objects.
Utilize Proper Techniques When Connecting Slings to a Load.
Connecting slings to a load with tools such as shackles, chain, rope and synthetic webbing should be done with proper techniques. When using chain slings, ensure that the connecting parts are free of knots and binds. Also, check to make sure you have the right matching pin degrees.
With rope slings on the other hand, it is important that they be secured properly before use as incorrect attachment can cause extensive damage and even lead to accidents. Synthetic webbing slings should be fastened by threading looped end of sling through buckle slot or else it can lead to slipping from its anchor point during rigging operations.
Maintain Proper Communication Between Crane Operators, Signalers, and Those Working Around Moving Loads.
Understanding the loads that are being moved and communicating this information in a clear and timely manner is essential for successful hoisting and rigging. Crane operators, signalers, and those working around the moving load should be aware of each other at all times so that in case anything goes wrong, they can act quickly to avoid potential accidents.
It is especially important when the surroundings are filled with distraction such as loud machinery noise or poor visibility. Good communication improves both safety and efficiency of your work operations.
