The service area is in full development in the world, and it is proven the benefits of outsourcing services to large companies, which deliver services and manufacturing experts can focus only on production of their products. In the case of cargo handling is no different, many factories hire specialized companies to reduce fixed costs and factory overhead. And with the intense competition in the market, service providers are increasingly seeking to reduce costs in order to offer services at competitive prices. So if we see a growing need to train its employees to perform services faster and with better quality. In this work, will be a handbook of technical procedures for preventive maintenance, as well as a catalog of parts required to perform the same for Toyota 8 Series forklifts. Will be developed also tools to control and carry out the preventive maintenance of these trucks, such as Check-list and a manual of tools needed for each procedure. The results show that service quality has improved considerably and the cost of wrong parts decreases more than 15%

A manutenção dos tratores agrícolas pode ser considerada um conjunto de procedimentos que visa a manter o equipamento nas melhores condições de funcionamento, propiciando aumento da vida útil, evitando danos prematuros, eliminando os já observados e concorrendo para maior segurança no trabalho. Essa conduta, apesar de simples, exige atenção e cuidado semelhante ou até maior quando comparado a outro veículo automotor. O presente trabalho teve por objetivo analisar a regularidade e a qualidade da manutenção dos tratores da Fazenda de Ensino, Pesquisa e Produção da UNESP - Jaboticabal, utilizados para os mais variados tipos de trabalho, como aração, gradagem, pulverização e jardinagem, e avaliar a condição técnica dos operadores responsáveis pelas máquinas. Os resultados indicam que a manutenção diária não foi eficiente, o que pode resultar em redução da vida útil das máquinas. Quanto aos operadores, notou-se baixo grau de conhecimento técnico com relação à manutenção dos tratores e falta de treinamento específico.

Are presented on this paper, concepts of corrective, preventive and predictive maintenances, following the prerequisites for planning and implementation of a maintenance plan. You also find the theoretical introduction of some measurement instruments accompanied by the necessary and recommended activities during routine maintenances of the electrical equipments in a building installation. Using case study, it is possible to assess a real maintenance plan applied to two occupied floors in a financial institution. The developing of a case study consolidates the effectiveness of the present concepts on this theoretical introduction and shows that the current maintenance plan can be improved in order to obtain better results on company productivity and reliability of equipments. As a conclusion, we can notice the importance of a solid maintenance plan and the need of including this theme on the graduation in Electrical Engineering

The increase in energy consumption in the world has caused the electrical systems becoming ever larger and more complex. Because of that becomes necessary to use special tools to efficiently manage the equipment present in these systems. Nowadays a tool very used is the remote monitoring of assets which works collecting signals using sensors processing these signals and make them available to the system user. So the user can use informations that may assist him efficiently in making decisions when doing a maintenance. The system is technically efficient since it improves the measurement process and enables the asset management of a substation by using advanced technology for that and economically viable especially in cases where the user is subject to monetary loss due an interruption of power supply
