Dynamic Analysis Of Mini Climbing Crane

To bridge the existing technological gap between age-old traditional methods and modern sophisticated cranes for material handling, the Central Building Research Institute (CSIR-CBRI) Roorkee previously developed mini climbing crane with a lifting capacity of 1000 kg at a maximum loading radius of one meter. The developed crane exhibits considerable saving in construction time besides a large saving in manpower. This machine has been awarded the best technology NRDC Award. In this paper, the kinematic model of the mini climbing crane has been developed. Crane workspace and boom tip trajectory are evaluated using MATLAB programming by varying different geometrical and motion parameters. Modal analysis of the full-scale mini climbing crane is performed for its overall stability. Further finite element model (FEM) of the crane shows the load-carrying capacity of the existing design of the mini climbing crane. The full-scale 3D CAD model of the crane is used in the finite element analysis (FEA) using ANSYS software. The study presented in this paper will help further in design and development of a newer version of mobile crane for fast civil construction work.
