Confiabilidade humana na diminuição de falhas em freios eletromagnéticos: estudo de caso no terminal marítimo da ponta da madeira

Abstract

The constant search for improvement in asset maintenance reliability processes has been discussed in numerous forums on the subject by the industrial sector. This work has as its main objective to demonstrate the relationship between practical training and the reduction of failures in electromagnetic brakes of ore forklifts in a directly proportional way at the Ponta da Madeira Port Terminal located in São Luís do Maranhão and belonging to the mining company. The specific objectives were to quantitatively measure the relationship curve between the number of failures and the number of trained in preventive maintenance of forklift brakes, in addition to the reduction of Corrective Maintenance Hours (HMC) in this safety system. Using William Glasser's pyramid as a study parameter, the practice of learning presents itself as an active learning method that has gained fixation and use undertaken. The three factors (Workplace Design, Documentation and People) of human reliability were addressed, which aim to reduce human error and increase individual training. This paper explains the types of electromagnetic brake failures such as: excessive wear of brake pads and plates, overheating, component breakage, misalignment, contamination, electrical problems, wear or damage to the drive mechanism and lack of systematic maintenance. In turn, it was concluded that the greater the number of trained employees, the lower the proportion of equipment with failures or breakages in the assets. Mandatory element that consists of the presentation of the most relevant points of the body of the work.
