And, we don't have the vagues idea what the hell we are cookin or how it works.
You are looking at several different cookbooks and debating whether we should use a pinch of salt or a pinch and a half, however much that is and whatever kind of salt you are using. RE: Design of lifting lugs BENDOG (Structural) The Ricker article also references the Blodgett book. I have not had time to compare this with BTH-1 calc by calc.Īnother note - If I remember correctly, The ASME books reference AWS D14.1 which uses a lower allowable tensile value.
#Lift lug design how to#
1991 (+ Errata 2004 4th Qtr.) Uses AISC 9th ED and shows how to modify for greater safety factors. Ricker - AISC Engineering Journal 4th Qtr. This follows the David Ricker Article (not BTH-1)ĭesign and Construction of Lifting Beams by David T. This was part of a continuing education course. P.59 - Design of Stiffened Plate Lifting Beamsĭesign/Evaluation of Overhead Lifting Lugs by Clement Rajendra,PE - This is an example calculation in Mathcad format (usuable without Mathcad). P.53 - ASME BTH-1 Pinned Connection Design Provisions Two Articles by David Duerr in ASCE Practice Periodicial on Structial Design and Construction May 2008 I believe OSHA will reference ASME B30.20. (~$60 from ASME) Design requirements used to be contained in ASME B30.20 which now covers safety requirements. ASME BTH-1-2008 (replaces the 2005 version) - Design of Below the Hook Lifting Devices.
