Spreader Bar Calculation - Free download as PDF File (.pdf), Text File (.txt) or read online for free. A spreader beam is designed to take primarily compressive loads, as can be seen in the figure above. Typically lifting beams do not have bracing to resist either of these movements (a single symmetric cantilever beam with no external bracing to stabilize the beam), therefore the lateral bracing spacing is defined as the distance between the outermost lift points of the lifting beam. Spreader beams are some of the most popular below the hook lifting devices in the material handling industry. Rig your spreader beam correctly As an example, if you were to hoist a large rectangular load, the safest way to set the chains or slings is to have a two leg chain sling below each end of the spreader beam lifting points. We partner with organizations to assess, transform, and continuously improve their hoisting and material handling activities by adapting and applying our structured methodology, expertise and solutions. Crane and rigging performance evaluations may focus on crane and rigging usage, inspection, and worker skill levels and have the potential to reveal current status compared to recommended improvements. Do you have an idea for a topic that you would like us to cover? 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.

Pad-eyes are one of the smallest and most universally used structural items in the maritime and Oil & Gas industry. Just like lifting beams, spreader beams are used to widen the available lifting points on rigged loads and keep lifting slings at a 90 angle relative to the horizon. [] ASME B30.20 & BTH-1: Introduction to Below the Hook Design []. Therefore, we are looking at a beam that is lifted from the centre and loaded at the ends. We work for the same cause! The bar redirects compressive load away from the suspended load and diverts it into the spreader bar. d= = = 12.07 in. description of load: max. ASME B30.20 defines the safety requirements for below-the-hook lifting devices including marking, inspection, construction and operation, whereas ASME BTH-1 defines the design requirements for developing these lifting devices. Battery Beams. Service Classes 1 through 5 cover load cycles from 20,001 through 2 million load cycles. A simple lifting beam is shown below: We can see that it has a lifting eye at its top in the middle, while the eyes below are used to connect the slings to the lifted object. spreader beam design spreadsheet All-Ways Rigging Gear provides both lifting beam and spreader beam options. As can be see from the allowable stress plot, the short beam is permitted to achieve full bending stress (with safety factors), but at a certain point, the allowable bending stress is reduced, to account for the buckling strength of the beam.
