Abstract
Nowadays, in the field of industry and commerce, heavy loads have to be removed by various methods and moved from one place to another. Mobile cranes in order to overcome these tasks are in common use. One of the problems that prevent the safe and long-lasting operation of mobile cranes and trigger other problems over time is the deflection in mobile crane booms. Continuous work is being done to ensure safe operation of mobile cranes, to minimize time losses due to continuous failure problems and to increase the lifetime of mobile cranes. Based on literature studies and researches it has been found that the crane operator or crane manufacturers use only the load diagram without taking into consideration the deflection formed in the boom, and about 15% increase in the torque generated in the final crane is ignored. In this study, the deflection in mobile crane booms were calculated by Finite Element Analysis (FEA) in ANSYS program. The static analysis of the mobile crane booms was resolved at different angles and different load conditions of the booms. Manufacturing tolerances in general (thickness of sheet metal used in booms, manufacturing tolerances of booms, etc.) and environmental factors (wind speed, temperature, etc.) have been neglected. When the reverse engineering is considered to be rapid advance, the mobile crane lifting diagram is presented to the crane operator more safely by measuring the deflection of the crane booms using photogrammetric techniques. In this study; the deflection in the mobile crane booms, it is possible to obtain high accuracy results in short time by using the reverse engineering method photogrammetric techniques. The deflection in the mobile crane boom is theoretically calculated by Finite Element Analysis (FEA) in the ANSYS program.
