Analysis and Optimization of 270 Degree Jib Crane Deflection: A Review

Jib cranes are widely used in industrial facilities all over the world. A typical jib crane consists of a top beam which is rotating around a fixed column. This configuration may be referred to as an L-shaped structure. Current material handling systems exhibit anisotropic behaviour. That is, their two planar degrees of freedom require different amounts of force input from the operator. Movement of these devices is correspondingly difficult. One of the three most prevalent material handling devices, the jib crane, is selected for research into creating isotropic motion. Deflection occurs of T-section as a span of Jib crane which is mention in this project, to optimization of deflection to increase modulus of elasticity. Analysis showed that a T-section will withstand large transverse deflection without in-plane ply failure; the predominant failure mechanism is delaminating in the fillet region. Especially Jib Crane used for circular material handling, it menace radial work.
