Considerations regarding the use of hydraulic drive systems in the construction and maintenance of wind turbines

Abstract

In the current world scientific-technical context, the boundaries between the applications of the various engineering fields are in a continuous movement and interweaving; the field of hydraulics is a representative one for this, lately hydrostatic drives entering new areas. This material presents some considerations regarding two types of applications of the hydraulic drive systems dedicated to the wind turbines, respectively: 1) applications meant to replace a gear transmission, from the construction of a wind turbine, with a hydrostatic transmission; 2) applications intended to replace the crane, necessary for the installation and maintenance of a wind turbine, with a hydraulic pole, provided with a removable hydraulic cylinder, powered by a pump assembly with double overcenter valve.
