Hydraulic Lift 1. INTRODUCTION Hydraulic lifting machines are widely used for the lifting, moving and pushing function in mining, construction and steel industries and in material handling equipment. Since 1950s the applications of hydraulic systems have been started in the industries and this form of power has become standard for the operations of industrial equipment. Today, modern automation technology has a very important place for hydraulic systems. The reason for this is that hydraulic systems are simple, versatile and efficient for the transmission of power. The main job of a hydraulic system is the transmission the power as the power is changed from one form to another. As these hydraulic systems are popularly used in the manufacturing and production plants, therefore it is required that they are reliable and efficient equipment to achieve the desired results from them like transmission of large amount of forces with the use of smaller components which means good power...
Safety Systems s in Modern Cars Introduction The most common cause of road accidents is the reduction in driver's attention due to fatigue or simply because the driver is devoted to other tasks such as tuning the radio, phone use and communication with traveling companions. Using qualified estimate it can be assumed that with the application of "intelligent" systems in vehicles, over 50% of human lives could be saved. In recent years the most attention was given to improving the passive safety of vehicles, making vehicles of today four times safer than they were in the 1970s [29,32,33]. Vehicle safety is also an element of competitiveness; therefore vehicle manufacturers are paying increased attention to this issue when developing new cars. The modern car is designed with particular emphasis to ensure a high level of safety of passengers and other road users. To ensure a high level of security, vehicles are fitted with systems that support certain conducting activities...
