Lifting beams and lifting bars have become an integral part of the complex crane, rigging, and lifting activity. Usually the emphasis is to design a two point lift spreader beam of a particular capacity by selecting 3 standard cross sections, Universal I Beam, Square hollow section and circular hollow section and subsequently suggesting the appropriate cross section for the spreader beam. This efficient method of rigging redirects compression forces away from the load and in to the spreader bar. Also in their use of materials, so theyre typically smaller, lighter, and economic to design and manufacture than a lifting beams.
Stress analysis is one thing, but if you are in the US there is a mandating code that you need to design spreader bars to. Spreader bars are normally made out of pipe and have top and bottom lifting points on opposing ends. Can I take more that one course at a time? Some common profiles are shown in Fig. 9.46K subscribers While spreader beams and lifting beams are the most popular types of below-the-hook lifting devices, there is a lot of confusion about the differences between the two.
