Which type of beam requires more caution when lifting loads?

Non-fixed beams are often considered to require more caution when lifting loads due to their ability to move or rotate under load conditions. Unlike fixed beams, which are securely anchored and typically provide a stable support structure, non-fixed beams can experience shifts or changes in position as loads are applied. This mobility can lead to increased risk of instability or failure if not properly managed during lifting operations.

When lifting loads with non-fixed beams, operators must be particularly aware of factors such as load distribution, potential for sway or bending, and the overall integrity of the beam supports. Close attention to these elements helps prevent accidents and ensures that the lifting procedure remains safe and effective. It’s crucial to assess the beam's condition and the load's weight before proceeding, reinforcing the need for additional caution when using non-fixed beams in lifting scenarios.
