Cranes are having very wide application in material lifting and material handling requirements. Cranes are widely used in the heavy industries as well as heavy construction sites and for road side assistance. Many types of cranes are available, different mechanism have been used for building a crane. Most commonly used mechanism is a simple four bar mechanism. This project deals with the design and analysis of 5tonne capacity crane by using CAD and Analysis software. To determine the stress and displacement we will perform static analysis. This project is very much useful for designing a crane using four bar mechanism as per the customer requirement. This project involves the designing and analyzing of crawler telescopic crane for limited weight lifting capacity of 5 ton. This involved gathering of functional and structural requirements of crawler telescopic crane from the resources available, Design Calculations, CAD model generation, Finite element analysis. By performing Finite Element analysis with Linear static conditions with 5 ton Weight at extreme extended position, maximum displacement of 2.1 mm and maximum stress of 159 MPa obtained in Design of smaller boom. This maximum stress is observed in frame structure where structure material (AS3679 grade 350) has yield stress of 330 Mpa. As the displacement obtained in the assembly are very less, maximum stresses should be considered for the result comparison. It can be concluded that a linear static analysis of crawler crane is performed with the following boundary conditions. (Mother boom is constraint in all the directions at pin joint location and hydraulic connections and force due to 5 ton load is applied on smaller boom at hook location) are safe as maximum stresses obtained are well within the yield stress of crane material (ss 320) with factor of safety 2.
