Automated Power Controlled Jib Crane Design for its Degree of Freedom

Abstract

The movements of most of the cranes are hindered by their own limitations and non-synchronic movement of parts while working. The research focuses on two aspects, first being the jerking on the load during tangential movement or the inertial force applied on the load. Second being the possibility to provide four degrees of freedom to the crane where the boom has two degrees of freedom, trolley with rope and pulley arrangement would have remaining two degrees of freedom. Research tries to implement few new parts into the system and replacing few mechanical systems with new customized system. A typical jib crane has three degrees of freedom with one rotatory and two lateral motions. And the lateral motion on the trolley needs dual power supply in operation for two different motions. This research offers two solutions for this anomaly, first adding a powered trolley that can accelerate the weight, second changing the motion style by using modified level-luffing method into the jib crane design. The agenda behind all these steps is to make the crane more efficient and increase it’s scope.
