Projecção de uma garra mecânica para movimentação, içamento e manuseio de carga na African LME

Abstract

This report aims to design a mechanical block grab for moving, lifting and handling of steel weights used in load test of overhead cranes of African LME’s clients to improve the quality of load test in this company. Overhead crane is a type of heavy duty machinery that is capable of moving extremely heavy loads and equipment from one location to another in safe and precise manner using the overhead space of a manufacturing facility. The load test of overhead cranes is made using the following main equipments: Bow shackles, Slings and weights. The load test is conducted to cover the following: • to verify the configurations of a lifting appliance such as the amount of deflection or degree of inclination of a mast or a span of a lifting appliance; • to check the functions of the hoisting, slewing and travelling mechanisms of a lifting appliance, with particular attention to the performance and efficiency of the braking system for each of these motions.
