Design Optimization of Knuckle Joint Crane Lifting Mechanism by Using Particle Swarm Optimization

Mobile cranes are specialized machines designed for lifting and moving heavy loads. They feature either a wheeled or tracked chassis and are widely used in industries such as construction, heavy manufacturing, energy, and maritime operations. These cranes utilize hydraulic systems and mechanical forces to lift objects from elevated or confined spaces employing extended arms and lifting attachments. Efficient operation depends on optimizing weight and capacity, as excessive loads or dynamic forces can lead to safety risks or mechanical failures. This research focuses on optimizing the dimensions of a knuckle joint boom crane's lifting mechanism to maximize the moment arm and minimize acceleration, employing the particle swarm optimization method.
