The Design And Implement Of 900T Pneumatic Girder Gantry Crane

900T Pneumatic Girder Gantry Cranes and 900T Transportation Girder Vehicles, 900T Span Carriers are designed for high speed rail projects. They are the key machines in the transporting and constraction 900T girders. The 900T Penumatic Girder Grantry Cranes are especially designed for carrying and transporting girder in the girder producing factory.This passage will tell you the design and implement of 900T Pneumatic Girder Gantry Cranes which is working for the constraction of high speed rail project of Zhenzhou-Xi'an subsection. Because all the function of this machine is drived by hydraulic system, the work contains not only the design of mechanical system but also the design of hydraulic system and the design of electrical control system.First of all, it is needs to do general calculation to get the general data for design work. It contains resistance and drive power calculation, and the design and analyse the configuration of main beam, which use software Ansys. Then do general design of mechanical system and hydraulic system according to the function and basic data which calculated in the beginning. It contains drive system, suspention system, steering system, hoisting system, lifting instrument moving system. At last design electrical control system which contains controller selection and control system design. And then design the program flow chart, write program, debugging it and write to the controller, to implement the design of the 900T Pneumatic Girder Gantry Cranes.
