M.N.V Krishnaveni, M.Amareswari Reddy, M RajaRoy Crane hooks are highly liable components that are typically used for industrial purposes. Failure of a crane hook mainly depends on three major factors i.e. dimension, material. In this paper load carrying capacity is studied by varying the cross sections. The selected sections are Circular, Trapezoidal and T-section. The area remains constant while changing the dimensions for the four different sections. The crane hook is modelled using SOLIDWORKS software. The stress analysis is done using ANSYS 14.0 workbench Educational version. It is found that T cross section yields minimum stresses at the given load of 6ton for constant cross section area among three cross sections. The stress distribution pattern is verified for its correctness on model of crane hook using Winkler-Bach theory for curved beams.Three
Design & Fabrication of Hydraulic Floor Crane 2014 CHAPTER-1 Introduction
These hydraulic floor cranes provide an efficient, low cost alternative to other material handling equipments. Strong, robust, sturdy and built to very standard, these cranes are maneuverable in loading, unloading and shifting of heavy loads. Crane structure consists of chassis, vertical column, horizontal arm, and the hydraulic pump with cylinder assembly. The box crane can take heavy loads effectively, avoids damage under rough and unskilled handling. The hydraulic cranes used in the industry are efficient but they only have the ability to lift the load and put it down at some other position. In this general design, the arm of the crane moves in the vertical plane only, i.e it has constrained motion. The aim of our project is to redesign the hydraulic crane and give its arm the rotational ability. The ball bearing provides rotational motion to the column. The hydraulic crane was invented in Newcastle by William Armstrong in about 1845 to help load coal into barges at the Quayside. The main aim of the project is the design, analysis and production of a hydraulic floor crane having vertical arm motion of 360 degree, horizontal arm motion up and down as well as movement of carrying hook using pulleys.

Review of Overhead Crane and Analysis of Components Depending on Span
The main aim of this paper is to study various components of electric overhead crane, types of overhead cranes, difference between single girder and double girder cranes on various parameters and to find the effect of increase in span on crane components. Planned and unplanned requirements may necessitate changes in span. The distance between two gantries may get modified during the shed building of factory or the crane in one bay of factory needs to be shifted from one bay to other which have different span. In such condition we have to modify the existing crane to suit the required parameters.Electric overhead crane having 10T capacity and 20m span is to be modified for 22m span. We will study effect of increase in span for various components like long travel wheel, long travel motor and long travel brake.
Design and Analysis of 50 Tonne Crane Hook for optimization
Hooks are employed in heavy industries to carry tonnes of loads safely. These hooks have a big role to play as far as the safety of the hoist loaded is concerned. With more and more industrialization the rate at which these hooks are forged are increasing. This work has been carried out on one of the major hoist hook carrying a larger load comparatively. So in present work the solid modeling and finite element analysis of crane hook has been done using Solidworks and ANSYS workbench. For analysis purpose virtual model of crane hook is prepared by picking data from design data book. Curved beam flexure formula is used for determination of stresses in crane hook analytically. Finite Element Analysis have been performed on trapezoidal cross sections. To investigate the static stress results, both finite element method and exact solution method are applied and compare the stress results obtained by finite element and exact solution methods. From the output of these analyses it is observed that results obtained are in close agreement with each other and maximum stress concentration occurs at inner most surfaces.

Comparison of Analytical and Numerical Approach in Bridge Crane Solution
Manufacturing Technology
A crane bridge is a dominant component of all bridge crane. It is imperative to pay attention on its strength features and go through a strength analysis. The introductory part of this paper points out characteristics of a bridge crane, mainly a crane bridge and materials used to produce the crane bridge, namely S235 structural steel. The paper set out the strength analysis of the main girder of a single girder bridge crane model in the means of comparing analytical and numerical solutions. The calculations take into account the load of the main beam in its centre according to the standard STN 27 0103. The bridge crane model is designed for a 500 kg load carrying capacity. The numerical solutions are represented by finite element method (FEM) analysis in Ansys software. The intention is to determine the deformation of the main girder depending on the weight of a load and a hoist, to determine the maximum deflection and resulted bending stress. Furthermore, one of the purposes is to create the precise 3D CAD model of the main girder. The 3D CAD software Catia V5 was used to design the bridge crane model. The strength analysis of the main girder of IPE 100 profile was performed by the FEM analysis using the Ansys software and by analytical calculations. The results obtained by the computing software Ansys were only slightly smaller in comparison with the analytical calculations. Results obtained by Ansys can be considered as more accurate. It can be concluded, such the designed and strength-checked main girder can be in the future put into a production.
Solid Modelling and Finite Element AnalysisofEOT Crane Girder
The design of an overhead crane with a double box girder has been investigated and a study of a crane with 10 ton capacity and 12 m span length has been conducted. It is not possible for the real experimental studies to take into consideration the influence of the connections between the main beams and the rest parts of the construction, the influence of the longitudinal and transverse ribbings as well as the influence of the supports on the overall stressed state of the construction. Moreover, the researches that use for the majority of the test cases different strain measurements turn out to be quite hard and expensive. All these problems could be solved successfully by the use of computer modelling procedures. It is possible to perform 2D or 3D computer studies. The 2D computer studies give idea of the planar behaviour of the construction and lack the opportunity of showing the influence of supports or the connections of the construction. It is only the 3D models that could satisfy all the requirements for examining the general stressed state of the carrying metal construction. With regard to this, the creation of 3-D models for researching and analysing the behaviour of an overhead crane, becomes the main goal of the present work In the initial phase of the study, conventional design calculations proposed by Indian Standard Rules were performed. The crane design was modelled with solids Loads and boundary conditions were applied to solid model. Assign material to the solid model. Finite Element meshes were generated from the solid model. After a comparison of the finite element analyses, and the conventional calculations, the analysis was found to give the most realistic results. As a result of this study, a design optimization method for an overhead crane is proposed.

Cranes are mainly used for lifting weights everywhere. When desigining cranes, several factors must to be takan into consideration: weights, shocks, wind and ground. It means that design process requires very accurate calculations and several verifications. To shorten design process, a lot of metohods can be used. The use of the numerical method gives the solutions in short time. The main method used is Finite Element Method (FEM). This method gives designers an exact overview of stress and strain which occur in structures under loads. The aim of the study is to determine the state of stress occurring in the structure of Damen Crane Metalna SA Galati ,which can lift and manoeuvre the block sections of the ship up to 320 tons. This analysis is made up with the help of the FEMAP software which enables us to make evolved finite items – shell-type and beams. As a result, it has been seen that FEM is the most practical and easy to use method during the design process.
