Introduction:
The structural analysis of the crane component is carried out using FEA stress
analysis using Ansys 15.0 software. The result is examined and analyzed to arrive on
a conclusion whether the crane component is under safe working condition or not.
To check the stability of the model 1T capacity Jib crane is taken into consideration
and the horizontal member where the hook is mounted is stress analyzed.
Fig-1: Jib Crane with 1T capacity
To check the maximum deflection and maximum stress maximum load I.e. 1T is
loaded at the end position of the horizontal member. The structure is made of
structural steel. The structure is fabricated from I beam and pipes. All the members
are welded using 7018 welding rods.

Fixed Support Nil At mounting points of
the vertical member
Force 1T Vertical downward

The results indicate that stress analysis of the structure.

Additionally, the following are observed.
 The fundamental frequency of the Structure.
 The natural frequency of the structure.
 During loading, maximum stresses are observed on the
end portion of the horizontal structure.
 The maximum Strain and principal strain.
 The maximum stress and principal stress.
 The total deformation and the maximum deformation.
Summary:
This technical report is about the stress analysis of the structural member of
the Jib crane. All the members of the structural member is fabricated from
structural steel. All the joints are welded and before welding joint
preparation is done. 2-3 mm clearance is maintained before welding to
absorb the thermal expansion and heat generated due to welding process.
The following parameters are considered for the stress analysis
 Input geometry of the structure was provided in STP/IGS
format (Figure 2).
 The weight of the ref plant is around 484 kgs (approx.).
 Finite element model is developed using ANSYS workbench
