“…Part 1: General) [5]. Several authors [3,7,10,11], engaged in problems of steel rope stress, their damage in operation, in experimental and simulation verification for different types of ropes and lay types, prove that rope under stress requires special attention. The stress states resulting from different kinds of loading [3] are often not included in calculations according to standards [1].…”

This article describes a specific analysis and evaluation process of a foundry crane installed in a steel mill. The main task was to analyse the possibility of increasing the lifting speed of the crane in order to improve the efficiency of the production process. The condition of the steel supporting structure of the given foundry crane was assessed by means of the performed experimental measurements and calculations. The present article describes the special experimental/analytical methodology for the evaluation of the crane steel construction and lifting and travelling mechanisms. Furthermore, the required modifications of the individual crane construction parts are explained.

For studying dynamic characteristics of ultra-deep mine hoisting steel wire rope, according to the differential equation of mine hoisting steel wire rope tension and deformation in the lifting process, we establish the corresponding dynamic simulation model using Matlab-Simulink, carry out simulation experiments according to the ultra-deep mine simulated test parameters, change the value of acceleration and velocity in the lifting process, get variation rule of rope tension and deformation in the lifting process, study the influence to tension and deformation and vibration frequency from acceleration and velocity, provide the theoretical basis and data support for optimal hoisting system design.

“…Os cabos de aço estão sujeitos a problemas de desgaste devido ao atrito com outros elementos das máquinas, além de cargas externas de tração, torção e flexão [1]. Diversos casos de falhas de cabos de aços são encontrados na literatura [1][2][3][4][5][6]. As falhas podem ser devidas a problemas de redução de seção dos fios dos enrolamentos de cabos por causas relativas a desgaste por fricção, sobrecargas de tração, fadiga, alterações microestruturais, principalmente formação de martensita não revenida, por causa do aquecimento devido ao atrito ou por descargas elétricas.…”

ResumoO presente estudo trata da análise de falha de um cabo de aço utilizado em grua de construção civil. Para a análise da falha foram feitas metalografia, microdureza, análise dimensional e análise por microscopia eletrônica de varredura. Também foram feitos ensaios de tração, a fim de determinar a diminuição da resistência mecânica em decorrência de diminuição de área do cabo. A análise em campo detectou a presença de um dispositivo de acionamento do motor da grua que mantinha contato com o cabo e foi o responsável pela falha. Os resultados demonstraram que todos os fios estavam desgastados. Na maioria dos fios foi detectado aspecto de fratura plana frágil. A análise metalográfica e de microdureza não indicaram nenhum defeito metalúrgico nos cabos. Os resultados do ensaio de tração indicaram a diminuição significativa da resistência mecânica devido à redução de seção dos fios. Palavras-chave: Fratura; Desgaste; Cabo de aço; Análise de falha. FAILURE ANALYSIS OF WIRE ROPE USED IN CIVIL CONSTRUCTION AbstractThis study deals with the failure analysis of a crane steel wire rope used in the civil construction. Metallography, hardness tests, dimensional analysis and analysis by scanning electron microscopy were performed. Tensile tests were made to determine the reduction of mechanical strength due to the wire area reduction. The analysis of the crane detected the presence of a motor drive device which was in load bearing contact with the wire and was responsible for the failure. The results showed wear in all the wires. Brittle fracture was detected in most of the wires. The metallographic analysis and hardness indicated no metallurgical defects. The results of the tensile test showed a significant decrease in mechanical strength due to reduction of the wire section.
