The following work was performed for the purpose of developing a plan condition based maintenance focused on improving the effectiveness of vehicle active critics of a manufacturer of concrete, mortars and derivatives, in order to reduce the hours of unscheduled stop, raise system productivity and minimize costs associated with maintenance. To accomplish this, we first conduct a diagnosis of the situation of the assets and a collection of technical information. Then, develop a program of lubricant analysis to determine critical systems. This analysis will provide the basis for selecting predictive tools, and from them determine the inspection procedures and other key aspects such as measurement points sampling routes, frequency of inspection activities. Once designed the entire program, will proceed to implementation, resulting in the detection of various problems that, if not corrected in time, can cause failures that would impact significantly on production, safety and environment.
