Maharashtra, India ---------------------------------------------------------------------***--------------------------------------------------------------------suspended directly from the outriggers (usually often called Abstract - To optimize the power transmission system for the slewing motion of a jib crane, including the gear, pinion, and geared motor, for all coordinates of the lifted load from the pillar center, the entire system needs to be carefully analyzed and refined. This involves selecting suitable gears, pinions, and a geared motor that can handle the load requirements and desired range of motion. The design should consider factors like torque, speed, efficiency, and safety. it is necessary to perform a comprehensive analysis and implement topology optimization techniques for the ring gear.
jibs).
A boom of jib crane experiences a maximum load when the load is acting at the maximum span / Outreach of the crane from pillar centre. Hence the motor and gearbox for jib crane is designed according to the beam under maximum possible loading condition.However, the actual movement of load happens at various coordinates from centre of the pillar which is different from the maximum value. The aim of this project is optimization of complete power transmission for slewing motion of jib crane which includes the gear, Pinion, and Geared Motor for all coordinates of the lifted load from pillar centre.
At present, while standardizing the gearbox, many factors like country standards, material available for fabrication & manufacturing, specifications of geared motor from the motor catalogue, material standards, lifting load variations and its frequency of operations are to be considered which cannot be followed directly from the global product for the Indian standards.
Crane companies in India sell its global products in Jib crane segment, and they want to localise the design as well as manufacturing and supply chain so as to make the design suitable to India market. It also will then cater to Indian standards, and the direct and indirect costs will also come down. This is the basic concept behind starting with this project.
1.2 Elements of jib crane
Key words: jib crane , ring gear , Optimization. 1. INTRODUCTION 1.1 Jib crane A jib crane is a crane which has cantilevered beam which consists of a hoisting mechanism and trolley. It is attached to a building column or either to a cantilever beam from an independent column mounted on the floor. It is a type of crane which is most often fixed near certain workstation so that the load movement in the specific zone is catered to. Jib cranes can be wall or Pillar (Tower) mounted. All jib cranes swivel and can lift and carry loads. Most jib cranes also traverse, in that the job crane can traverse the beam from the center of the circle to the edge of the circle created by the jib as the jib crane rotates.

The jib arm is usually mounted on a vertical pole or column (tower) and sometimes on an inclined jib. In other outriggerless structures such as derricks, the load is
