Rigging and slinging are integral techniques for safe and efficient crane operations. When handling heavy loads, a crane operator must be well-versed in various hitch techniques and safety procedures to ensure a successful lifting operation. Here are some of their applications and how crane and rigging services can help you optimize this process.
The Basket Hitch
The Basket Hitch is a versatile rigging technique that offers maximum load stability. It involves looping the sling around the load, and doubling the sling’s lifting capacity. This is especially beneficial when dealing with long or cylindrical objects. However, it’s critical to ensure that the load is well-balanced and secure, as the basket hitch does not prevent rotation.
Chocker Hitches
Chocker Hitches are known for their effective utilization when the load needs to be held tightly. This technique involves wrapping the sling around the load and feeding one end of the sling through the other. While this can securely grip the load, the hitch reduces the overall capacity of the sling. Therefore, it should be used cautiously and only when absolutely necessary.
Bridle Hitch
Bridle Hitch consists of several slings attached to a single lifting hook. This hitch is used to distribute the weight of the load evenly across multiple slings, making it perfect for large, bulky objects. While setting up a bridle hitch requires more time and expertise, it significantly enhances load stability and control.
Using a Single Vertical Hitch
The Single Vertical Hitch is one of the simplest and most common types of hitches. As the name suggests, the sling is used in a vertical position, with the load hanging directly below the crane hook. This technique provides excellent control and stability but is only recommended for loads that can be easily balanced.
Safety Tips for Rigging and Slinging
Safety should always be the first priority in any crane operation. Here are some safety tips to ensure secure and efficient rigging and slinging.
Protect Slings from Sharp Corners
Sharp corners can significantly damage slings. Always use corner protectors or padding to shield your slings from potential wear and tear.
Avoid Shock Loading
Shock loading, sudden jerks or bounces during lifting, can lead to sling failure. Therefore, always lift slowly and carefully to prevent any unexpected movement.
If Possible, Don’t Use Hooks
Hooks can potentially slip or disengage from the load. Whenever possible, use shackle attachments or direct coupling to the load.
Do Not Twist or Knot the Sling to Shorten It
Twisting or knotting a sling can significantly weaken it and cause premature failure. If a sling is too long, use proper rigging hardware to adjust its length.
Don’t Pull Slings from Under the Load
Pulling a sling from under a load can lead to uncontrolled movement and potential accidents. Always fully lift the load before removing the slings.
Use Safety Latches
Safety latches prevent the load from slipping out of the hook. Ensure they are always in place and functioning correctly.
