CATIA is 3D design software used across industries for product design. The document discusses using CATIA to design a crane hook, which experiences high stresses during use. It introduces crane hooks and their common cross section shapes (rectangular, trapezoidal, circular, I-section) and the tensile and compressive loads they experience. The author then presents their problem statement of designing a crane hook with a curved path and selected cross section. Their procedure involves sketching the curved surface, adding the cross section, and using multisection and solid modeling to create the hook and holder. Analysis of the final design is also mentioned.

1.INTRODUCTION TO CATIA
Abin Abraham 2
o CATIA is an acronym for Computer Aided Three-
dimensional Interactive Application.
o It is one of the leading 3D software used by
organizations in multiple industries ranging
from aerospace, automobile to consumer
products.
o CATIA is a multi platform 3D software suite
developed by Dassault Systèms
encompassing CAD, CAM as well as CAE.
o CATIA was accepted by more and more
manufacturing companies, Dassault changed the
product classification from CAD / CAM software
to Project Lifecycle Management. The company
also expanded the scope of the software.

o CATIA can be used at different stages of the design - ideate, draw, test and iterate. The
software comes with different workbenches (“modules”) that allow CATIA to be used
across varied industries – from parts design, surface design and assembly to sheet metal
design. CATIA can also be used for CNC.
o CATIA was extensively used in the design of the Mirage aircrafts; however the potential
of the software soon made it a popular choice in the automotive sector as well.

2.INTRODUCTION
❑ A Crane hook is a type of a curved beam with a structural
curvature.
❑ Crane hooks are the components which are generally
used to elevate the heavy load in industries and
constructional sites.
❑ Crane hooks are highly liable components and are always
subjected to failure due to accumulation of large amount
of stresses which can eventually lead to its failure.
❑ Crane hooks mostly employed in transport, construction
and manufacturing industry. Overhead crane, mobile
crane, tower crane, telescopic crane, gantry crane, deck
crane, jib crane, loader crane are some of the commonly
used cranes Abin Abraham 4
