Design Process of Change of Functioning of a Power Shovel to a Lattice Boom Crane of 300-Ton Capacity 2016-01-8126

The aim of this paper is represented design and manufacturing process of change of functioning of a scrapped shovel (Ruston Bucyrus R32) to a lattice boom crane of 300-ton capacity. Capabilities of the structure, changed components, additional required components (e.g. boom, mast, winch…) and modifying critical dimensions of this shovel were surveyed. In this paper, some of the 300-ton capacity lattice boom cranes of various companies were considered and critical dimensions that play an important role in system stability were surveyed. After that, their major dimensions were compared with those of a common shovel. In order to design the structure and components of this shovel-based crane, static, dynamic and wind loads were calculated. Finally, the critical dimensions of the shovel related to chassis and crawler were modified. This crane was used for lifting heavy machineries in the right zone of the main body of Seymareh dam site (Ilam-Iran) and played a vital role on that project.
