Spreader beam calculation This research provides a comprehensive analysis and design calculation for a spreader beam used in lifting applications. Some common profiles are shown in Fig. lA. This arrangement enables the sling to lift, e. Material specifications and results beam with a single hook point in the centre will be in bending whereas a spreader beam will largely be in compression. 1 Spreader Beam: ASME BTH-1 Page 3 of 5 2 Description 3 65,000 W [lb] - Weight of the load 4 3 Nd - Design factor 5 Material: 6 SA-36 Material 7 36,000 Fy [psi] - Yield strength 8 29,000,000 E [psi] - Modulus of elasticity 9 Dimensions: 10 180 L [in] - Length of beam 11 2,700 I [in^4] - Moment of inertia 12 12. If we resolve the forces on the whole beam, we get the force diagram as above. 5, making the total weight 33069 lbs. RICKER Lifting beams (also known as spreader beams) are used to assist in the hoisting process. Spreader Beam Calculation (c) 2009 Dharma Sakti Engineering 41450. doc), PDF File (. txt) or read online for free. Below-the-hook lifting devices such as spreader bars and lifting beams must be designed in accordance with ASME BTH-1 and are to be manufactured and used in accordance with requirements of ASME B30. It first calculates properties of the steel pipe used for the beam. 1. Aug 5, 2020 · Fig 1: Arrangement of a spreader bar Spreader beam vs Lifting beam. It calculates the design load, the Dynamic Amplification Factor (DAF) and lifting point loads Spreader Beam Calculation - Free download as PDF File (. This document summarizes the key parameters and calculations for a simple spreader beam. The lift beam itself is to be designed in accordance with a suitable national or Mar 16, 2018 · Conversely, for a telescopic spreader bar with a centre pick point and two slings out to the ends of the spreader bar the loading on the beam would be primarily compressive, although if the ends of the spreader bar are set up such that bending is applied to the ends of the spreader bar, then a combination of load calculations must be utilized. This document provides calculations to check the adequacy of a spreader beam design for lifting a 286,000 kg load. All Description. The document summarizes the selection and stress check of a spreader beam. 16 m height, resulting in a sling load of 209. Typically a simple spreader will have a suspension sling which connects the lifting machine hook to the ends of the spreader which are then connected to the load. We explain everything you need to know about the capacities of the load beam you need. Bending stress calculations confirm the beam design is acceptable based on its material yield strength and compact Spreader Beam Calculation - Free download as Word Doc (. Most erectors and riggers accumulate an assortment of lifting beams during the course of time. The basic lifting beam is shown in Fig. The document provides formulas to calculate the maximum stress and deflection of beams with uniform loads or a single load at the center. It is subjected to a hook load of 363 kN at a 60 degree angle and 4. This can influence the type of section with spreader beams often fabricated from Circular Hollow Sections (CHS) or other closed sections. The beam is made of S275 steel, has dimensions of 25x25x2 mm, and is 4. Design and Construction of Lifting Beams DAVID T. Key details: - The total weight to be supported is 22046 lbs (10000 kg) with a safety factor of 1. 20 which specifies requirements for marking, inspection, construction and operation. 20 & BTH-1: Lifting Beam Design. 8 m long. 1A. A spreader beam is designed to take primarily compressive loads, as can be seen in the figure above. The analysis shows the spreader beam meets design requirements with stresses and deflections below allowable limits according to the BS 5950 code. It assesses the reaction forces acting on the beam due to weight loads, evaluates stress and safety factors using international standards (API 17D), and includes detailed calculations for padeye design and shackle selection. - The compression stress was calculated to be 969. ASME B30. It includes design data such as the beam dimensions, material properties, loads, and geometry of the lifting lugs. 155 c [in] - Distance to neutral This document provides calculations for the design of a spreader beam and its lifting lugs. g. At the outset, it is important to clarify the difference between a spreader and a lifting beam. It then checks that the beam can withstand: 1) the axial compressive stress from the load, 2) the shear and tensile stresses on the lifting plates, and 3) the combined bending and shear stresses on the plates. - An H200x200x8/12 beam was selected with properties including an area of 9. Lifting beams (also known as spreader beams) are used to assist in the hoisting process. 6 kN and compression on the beam of 104. At OX & RUD we have been manufacturing Spreader Beams or Modular spreader beam for many years. It describes loading assumptions and analysis methods using STAAD Pro software for both 4-point and 2-point lifting conditions. Calculations show the bending and buckling stresses exceed the This document provides specifications for a spreader beam including its material properties, dimensions, bending stress calculations, and gusset spacing requirements. 44 psi, which exceeds the allowable stress of 295 . This arrange This document provides analysis and design calculations for a 10 ton spreader beam. pdf), Text File (. The spreader beam is made of SA-36 steel, has a length of 5,500 mm, and can support a maximum load of 80,300 kg. 8 kN. 85 in^2. Mar 4, 2016 · (b) Design of weld joint of the eye-bracket with the spreader beam for shear strength (50% of the allowable stress is governing) DESIGN OF ADJUSTABLE SPREADER LIFTING BEAM of Standard Profile "HEB Series" spreader, often called a spreader beam, is actually a strut loaded in compression. This Excel sheet helps the user check the strength and adequacy of a spreader beam used for lifting operations. nvrix mhve lbigfd jtlg jcod pjahr ivwocmw ecjy rhq kdhs igafzm kgmt gnmfxamg ybwlh bmniczan
