These lugs attach to a lifting sling which can be made from chain, wire rope, round or web slings to evenly "spread" the weight of the load and connect to a crane, hoist, or other lifting machine. However, the primary load on the spreader is compressive stress. ASME B30 & P30 Developments1.5 Hours | Mike Parnell, ITI presents on new ASME volumes, major standard updates, and interpretations. Square tubing design with adjustment pins. Based on the BTH-1 calculations, if the beam length is short enough the beam yield strength limits the lift capacity of the beam, but if the beam length is over the lateral bracing spacing requirement (per calculations in BTH-1), the buckling strength of the structural member defines the allowable lift capacity of the beam, resulting in a reduced maximum allowable bending stress. Step 2: Determine the Material You'll Be Lifting. If we resolve the forces on the whole beam, we get the force diagram as above. stress analysis of precast prestressed concrete beams. TSOC offers Short Span, Standard Duty, Basket Sling, Universal Lifting, Adjustable Lifting, Four Point Sack, Four Point Adjustable, and Adjustable Telescopic spreader beams for cranes. In other words, a below-the-hook (BTH) lifting device is a tool or mechanical device that attaches to a crane or other lifting apparatus, and grabs and secures a load so that it can be moved safely from one location to another. Spreader bars are a long beam that hold the legs of the lifting slings apart. Lug Analysis Calculator MechaniCalc.

The bar redirects compressive load away from the suspended load and diverts it into the spreader bar. They go by many names and the terminology is useful, but names are trivial compared to the functional distinctions between beams themselves which can come in all shapes, styles and sizes. 3. Because they use two lifting points instead of one singular lifting point, the weight of the load is distributed evenly across the beam. In this article, we will explore the design of a basic spreader beam and see what design checks are needed to establish the suitability of a spreader beam for particular lifting operation. They have two attachment points at both ends of the top side of the bar.
