Mastering the essentials of rigging operations involves understanding diverse sets of tools, each serving distinct functions critical for ensuring a secure and safe lifting process.
Explore the key types of rigging equipment.
Rigging Hooks & Shackles
Facilitating the secure connection of chains, ropes, slings, and various rigging equipment during the moving process, a rigging hook or shackle is indispensable for preventing slips in heavy loads while suspended in the air.
Comprising two integral components – a loop-shaped steel connected to a chain and a safety pin for secure closure – rigging hooks, including choker hooks, eye hooks, clevis grabs, and sorting hooks, play a vital role in ensuring stability.
The optimal selection of a rigging hook involves careful consideration of the following criteria:
1. Load weight
2. Nature of the object being moved
3. Size of the hook opening (ranging from 5/8 inches to 1 17/32 inches)
4. Angle of the hoist
5. Connection points from the top and bottom of the hook.
Wire Ropes
Supporting the load’s shape throughout the lifting process, this apparatus is commonly affixed to cranes using hooks, shackles, or swivels for efficient load attachment and movement.
Its strength and application are contingent upon several factors:
1. Rope diameter, with 6 x 19 and 6 x 37 standing out as popular variants.
2. Core material
3. Steel grade
4. Wire finish, including bright steel, galvanized, and stainless steel.
In accordance with OSHA 1926.251(c)(4) guidelines, each rope must be a seamless, continuous piece without any knots, ruling out endless rope slings and eye splices at the wire ends. Additionally, any eye splice in a rope should consist of only three full tucks.
Slings
A sling, a nimble and lightweight tool, partners seamlessly with wire ropes to effortlessly elevate substantial loads, offering both robust strength and equilibrium in maneuvering weighty materials across the site. Crafted predominantly from synthetic materials, slings manifest in two primary types:
1. Endless Sling: Forms an infinite loop configuration.
2. Eye-and-Eye Sling: Features flat, triangular, or twisted ends crafted from metal, polyester, or nylon.
Pulleys & Blocks
Pulleys and blocks collaborate seamlessly to facilitate the lifting of heavy objects with minimal force, offering essential support and diminishing the pressure needed for load elevation.
The pulley operates by encircling a rigging rope, connecting it to the object, and managing the rope as it lifts the load. Its sizes vary, contingent on the frame type, rope specifications, and sheave size employed.
Concurrently, the block acts as a stabilizing force, bearing the weight of the rope throughout the lifting process. Common block types encompass snatch blocks, square blocks, and swivel blocks.
Eye Bolts
Serving as a pivotal anchor point, this tool adeptly forms loops with cables in various rigging applications. Available in diverse sizes and materials, riggers can select the most suitable option based on their specific requirements. The following are common types of eye bolts:
1. Shouldered Bolts: Utilized for loading equipment at an angle.
2. Non-shouldered/Straight Bolts: Employed for vertically lifting objects.
3. Other Varieties: Including U-bolts, screw eye bolts, and more.
Selecting the appropriate eye bolt involves careful consideration of the following criteria:
1. Weight of the Load
2. Type of Sling Used
3. Angle of Loading the Object (e.g., angular, vertical)
4. Frame Material for the Bolt (e.g., wood, metal)
Steel Nuts
Steel nuts play a crucial role in anchoring a rigging system alongside eye bolts, offering versatility with various sizes and configurations tailored for different rigging applications. The selection process hinges on the total weight of the load and the type of thread employed, whether right-hand or left-hand.
Notable examples of steel nuts encompass:
1. Ball Ends
2. Dome Nuts
3. Hex Nuts
4. Lifting Eye Nuts
5. Wingnuts
Turnbuckles
This device effectively modifies the length or tension of cables, chains, ropes, and other tensioned rigging equipment. It features two threaded eye bolts, with one securely fastened to each end of a compact metal frame. Additionally, it is available in two variations: a stretching screw and a bottle screw.
Spreader Bars & Lifting Beams
These instruments establish a secure link between the object and the crane during lifting operations, providing essential stability for a controlled and manageable lift. The choice of these tools is contingent upon the specific characteristics of the load requiring support.
For handling substantial weights, spreader bars are the optimal choice. True to their name, these tools distribute the load over a wider area, facilitating easier and more efficient transportation. On the other hand, lifting beams are better suited for lighter loads, adept at bearing the entire weight from a singular point.
Safety Considerations for Rigging Operations
Prioritizing safety is paramount in every rigging operation, as crane and rigging accidents pose serious risks to both workers and property. According to the U.S. Bureau of Labor Statistics, over half of fatal crane injuries between 2011 and 2017 resulted from falling objects or equipment.
To mitigate these risks, strict adherence to health and safety regulations governing equipment handling is imperative. The Occupational Safety and Health Administration (OSHA) has outlined comprehensive guidelines, encapsulated in both OSHA 1926.753 (Hoisting and rigging) and OSHA 1926.251 (Rigging equipment for material handling).
