Abstract

Heavy Engineering is related to manufacturing of process plant equipment related to refinery and fertilizer, ship building etc.Manufacturing of reactor is related to heavy engineering industries. Reactor is made of two or more shell. Shell is an empty vessel which is manufactured by bending the plate. During welding of the vessels, vessels should be in a particular position for appropriate welding. For particular position of vessels, tilting is necessary. Tilting of vessel is an important part of heavy engineering industries. Tilting of vessel is done by use of two cranes, they have some limitation. Because of these reasons new mechanism required for tilting of heavy shell or vessel. Heavy shell tilting fixture is mainly used for tilting the shell from horizontal to vertical and vice versa. For certain types of application shell have to move vertical to horizontal at that time this fixture is used. During the time of assembly of Dished End and shell, both vessels should be in a horizontal position. At that time shell tilting will necessary. Second time during the heat treatment, vessel should be in a horizontal position for proper adjustment into furnace. Design and analysis of heavy shell tilting fixture for weight capacity 120 MT will use in this work. The design includes design of fixture, design of support stool, design of saddle, selection of wire rope sling. Dimensions obtained from design, have been used for G.A (General Assembly) drawing, 2-D manufacturing drawings. Modeling of 3-D components and assembly of tilting fixture have been done with the help of CREO software and analysis of 3-D structure and analysis with ANSYS
