J Jib crane is a heavy equipment lifting tool that is used to move a heavy load from one point to another, usually this equipment can be find in warehouse, construction area and harbor, in this thesis im going to analysis this jib crane structure with the purpose of finding the critical area of this jib crane while this jib crane is being given a load, in order to do this im going to use ansys, a software that offtenly used for structural analysis and other type of analysys the result I want to find in this analysis are: Eqivalelnt stress (Von-Misses stress), Normal stress with a different direction (X and Y) and the last is directional deformation. But before I gave this jib crane a load, the first thing that has to be done was to determine the shape and the size of the mesh and also gave this jib crane a support. From the analysis I operate, I always get the highest result in every type of analysis I ran (wheter it’s stress analysis of deformation analysis) when I put 3 ton of mass in jib crane structure , the result of Von-Misses stress is 181,35 MPa, result for Normal stress X direction is 106,78 MPa, result for Normal stress with Y direction is 39,263 and last the result for directional deformation is 9,3592 mm. It should’ve been noted that all of the result from different kind of stress is safe because it didn’t exceed the yield strength of structural steel whish is 250 MPa
