Electrical intermediate title thesis, electrical engineer title: Design of electrical control system for spider aerial work platform Abstract: Abstract: on the basis of analyzing the function and characteristics of spider aerial work platform, the spider aerial work platform electric control system adopts PLc controller. In order to ensure the safety and reliability of the working process, detection of important parameters using the redundancy design, and the reliability of the necessary measures in hardware and software design of the control system, in order to ensure the correctness of each operation, the maximum to avoid misoperation. - the implementation requires the use of safe, convenient and efficient. Keywords: spider type aerial work platform; electric control system; safety, there is a column, a column, car scissor, self-propelled scissors, jib, spider etc 1 introduction the reliability of aerial work platform, the spider type aerial work platform is due to its 4 legs placed the ground like spider legs and its name, its appearance, convenient operation, safe and reliable, flexible, large range, installation and maintenance, construction and installation of wind power equipment, shipbuilding and other fields are widely used in foreign countries [l]. At present, Chinas aerial work platform, large height products and special products, such as spider type large height platform, self operated aerial platform, still import mainly [z]. Different from other engineering machinery, operation frequency of the aerial work platform is not high, the load is small, but for the safety and high reliability requirements, therefore, in a stable and reliable mechanical and hydraulic sys
