Trail King's new Hydraulic Schnable System is engineered to load and unload wind tower sections without the use of a crane. Hydraulic cylinders lower and tilt the pivoting tower on the gooseneck into position for its tower supports to be hooked into the inner flange of the wind tower section. These cylinders then lift the wind tower off the ground and into the transport position. Because terrain at wind tower sites may oftentimes be less than ideal, the cylinders can also be used, if necessary, to adjust the ground clearance of the load.
Once at the site, the goosenecks lower the load to the ground and tilt their pivoting towers into position to be disconnected from the wind tower.
