Risk Analysis: A Crucial Step for Integrated and Attachable Lifting Points

A comprehensive risk analysis is mandatory before conducting a lift, whether utilising integrated or attachable lifting points. This analysis should consider the following key aspects regarding lifting points:

• The lifting point or lifting eye should not have any sharp edges.
• The lift point must be suitable for the hooks/shackles/slings being used.
• Wall thicknesses and edge distances must be assessed to ensure the load can be transferred appropriately into the structure.
• The product-specific marking must be provided.

Lifting Point Selection Criteria

Choosing the appropriate lifting point is crucial for ensuring the safety and efficiency of any lifting operation. Here are some key factors to consider during the selection process:

• Mass and Centre of Gravity: The payload's mass and centre of gravity are the primary determinants. Lifting points with a Working Load Limit (WLL) equal to or exceeding the load weight must be selected. Additionally, the centre of gravity will influence the number and placement of lifting points required for balanced lifting.
• Number of Lifting Points and Lifting Configuration: The number of lifting points depends on the number of legs in the lifting sling and the desired lifting configuration (single-leg, multi-leg). The chosen configuration will impact the overall WLL of the lifting system.
• Deduction Factors: External factors like tilt angle and temperature fluctuations can affect the WLL of a lifting point. Deduction factors specific to the anticipated lifting scenario should be considered during selection.
• Lifting Point Type and WLL: Based on the load weight, lifting configuration, and deduction factors, a lifting point with an appropriate WLL and suitable type (boltable, weldable, rigid, swivel) must be chosen.

Verification and Documentation

The selected lifting point should possess a valid test certificate conforming to the relevant standards. This certification verifies that the manufacturer adheres to stringent testing protocols, including proof load application, destructive tensile tests, and crack detection procedures.

Design and Calculation Resources

Providing engineers access to 2D/3D CAD design documents and calculation programs can significantly enhance the lifting point selection process. These resources allow engineers to incorporate lifting points directly into technical drawings while considering factors impacting WLL calculations, such as:

• The number of lifting strands/legs.
• Potential angle variations during the lift.
• The symmetry or asymmetry of the lifted object.

Simplified Lifting Point Inspection with RFID Technology

Regular inspection and maintenance of lifting points are essential for safe operation. RUD offers lifting points equipped with RFID transponders. These transponders contain unique identification numbers that a dedicated reader can scan to transmit data to cloud-based software. This technology simplifies inspection recordkeeping and allows for convenient access to vital lifting point information.

Lifting Point Purchasing Checklist

To streamline the selection process, consider this checklist when purchasing lifting points:

• Is the lifting point type specified in the project plan?
• How many lifting points are needed per component?
• What is the required WLL for the lifting point?
• Are there any specific design dimensions to consider?
• What are the anticipated loading directions for the lifting point?
• Are there any necessary approvals or certifications required for the lifting point?

By following these guidelines and utilising available resources, you can ensure the selection of the most suitable lifting points for your specific lifting applications, promoting a safe and efficient operation. RUD Australia has a team of experienced, CPEng-qualified engineers who can assist you in selecting the correct lifting points for your application.
