Design of Evener Beam for Lifting Plates

Boom or tower type crane consist hook facility to lift or move material and it is more flexibility than simple beam type horizontally established gantry crane. In this crane, beam is lifted by means of wire rope, link or chain to the distal end of boom and material can be lift by means of wire rope with lifting point. Beam is directly suspended using wire ropes and its move by boom crane. Wire ropes are fitted with lugs which are directly welded to the horizontally suspended beam for lifting material or objects. Generally, Beams are used to move slender materials specifically say slender plate as one industry application. Slender plate type objects are flexible in nature so, it may be sag or bend during a time of lifting because of only two lifting lug are generally used. Moreover, fixed size of beam is used for a single application of lifting plate so; this is a limitation of a beam, and in major cases it requires changing as application changes. On the other hand, due to two lifting point on a beam plate may be band or sag so it’s require to solve two problem simultaneously. Also it is not solution to simply weld more number of lifting points say lug to beam, but need of specific and optimum design is requirement which is detail describe in this paper.
