For the issues of well dredging problem in our cities, a kind of well dredging mechanical arm was designed, used for the dredging work in city. Its composing and working principle were introduced.The model of the well dredging mechanical arm was built and force analysis was carried out. The design of the hydraulic control systems and the parameters calculation of hydraulic cylinder were introduced.
