18m hydraulic tower, hot dip galvanized , This hydraulic tower is applied to 20kw, 30kw and 50kw wind turbine generators.

1 Summary for 18m hydraulic free standing tower

This hydraulic tower is applied to 20kw, 30kw and 50kw wind turbine generators. Compared to the traditional guy cable tower, hydraulic tower enjoys the advantages of handsome exterior and taking small room (burdensome steel wires); Compared to the traditional tapered tower, the most outstanding merit for hydraulic tower is that wind turbine generator can be erected and laid down automatically through the appliance of hydraulic system to achieve installation and maintenance. So there is no need the cooperation of the crane, which will save the installation and maintenance cost to a great extent.

Composed by three sections of steel pipe with different diameters, the hydraulic towers are supplied by tower base, hypo-cylinder, and hydraulic pump. Flanges are welded to the both sides of each tower for connections. Tower base will be placed on the foundation.
