Lifting equipment, Cost efficiency, Mechanical gripper, FEAAbstract
An innovation has been developed to support work productivity in the cement industry, namely a lifting aid equipped with a motion mechanism system, the assist mechanical gripper. However, it currently faces limitations in its initial purchase price for small-to-medium-scale cement industries due to the use of a control mechanism system. This final project aims to design a lifting tool based on a simple mechanical system that integrates a gripper with a lever and spring mechanism. The design method includes data collection, alternative design options, manual calculations, and digital simulation using finite element analysis (FEA). Test results indicate that the design of the gripper fingers, lever, spring, and spring cylinder is within safe limits, with safety factors of 2.9 for the gripper, 80 for the spring, and 5.3 for the spring cylinder. Cost validation indicates a production efficiency of 84% compared to commercial grippers.
