Modernization of the Hydrostatic Drive of Lower Gate Locks in Waterworks Gabcikovo

This paper deals with analysis of the combined load on hydraulic cylinder. Based on measurements of the parameters of the hydraulic cylinder and accurate calculations conclusions were drawn. Measurements were made on the lower hydrostatic drive gate locks at the waterworks Gabcikovo. Method of fixation of the hydraulic cylinder creates added bending torques which causes deformation of piston rod. The results are an effort to find relationship between dimensions, loading and safe operation.
