If you have a unique design challenge where you could use some engineering assistance, please contact us to see how we can help you. According to BTH-1 calculations, the short beam can be loaded to full yield strength (accounting for safety factors), but as the beam length (or lifting spread) increases, the stress reaches an inflection point where the allowable bending stress starts to drop off. (In.) The following chart shows a comparison of a W-Beam lifting beam with lifting capacity based on simple bending stress calculations vs calculations that account for buckling per ASME BTH-1.

This Excel sheet helps you calculate the Lift Point and Sling Loads for a two hook, two point lift using a spreader bar. This article is a brief overview of what is covered by ASME BTH-1, particularly with respect to the design of spreader bars and lifting beams. It is to be noted that the center of gravity (COG) of the lifted object has to be in line (on the same vertical) as the crane hook. (Available here). Bent bar hooks allow for 2" wide sling eyes lifting lug calculation asme mechanical code issues. We verify by the formula of question # 3 that for the 20 configuration we require a height of 1.37X, that is, 27.4 meters of height, which exceeds the predetermined height requirement in this example case..

Fillmore Parking Garage| 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. ASME BTH-1 This document defines design considerations including allowable stresses for shear, bending, compression, and connection design. I have extended your XLC Pro subscription by six months by way of thanks. Spreader beams are universally applied gear which is widely used in various types of lifting operations, onshore and offshore. Each of these models are Telescopic Spreader Beams rated at 60, 90 and 120 degree Sling . Both types of devices are used to keep the lifting slings below the device at or near a 90 angle (perpendicular to the horizon). Exam administration with Certified Practical Examiners (ITI Instructors) is also offered. 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. This type of lift subjects the beam to flexure (bending) and shear, with bending stress and lateral torsional buckling being the primary modes of failure. 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. 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. [] ASME B30.20 & BTH-1: Introduction to Below the Hook Design []. Along with stress, buckling is also a critical factor in lifting beams that must be addressed in detail to ensure that the . Battery Beams. Spreader beam design calculation xlsBy purchasing this spreadsheet you agree to the disclaimer and terms & conditions. The reason for this is crane capacity and required boom length required negates the use of additional shackles for normal spreader configuration.
