Method of transporting a blade for a wind turbine generator, the method comprising - attaching a blade root support frame to a root flange of the blade , where - the root support frame includes a main support part , which is supported by at least two legs , and an attachment part adapted for being attached to the root flange of the blade , and - a coupling part arranged for being connected to a transport unit , and - attaching a blade spanwise support frame to a spanwise portion of the blade , where - the spanwise support frame includes a cradle-like support part adapted to engage and support a spanwise surface part of the blade , and - where the spanwise support frame is arranged for receiving a first wheel base with at least two axles and four wheels, and - connecting the first wheel base to the spanwise support frame , and - connecting a transport unit to the root support frame , where - the transport unit includes a carrying structure and - at least one second wheel base with at least one axle and two wheels, and - where the transport unit before being connected to the root support frame , is moved into a position partly underneath the blade root, and where the second wheel base is underneath the blade and the carrying structure is underneath the root support frame , and where the cradle-like support part and/or the root support frame is supported by at least two legs , which are movable between at least a support position and a transport position as well as vice versa, and where movement of the legs is performed manually or using a power source. - attaching a blade root support frame to a root flange of the blade , where - the root support frame includes a main support part , which is supported by at least two legs , and an attachment part adapted for being attached to the root flange of the blade , and - a coupling part arranged for being connected to a transport unit , and - the root support frame includes a main support part , which is supported by at least two legs , and an attachment part adapted for being attached to the root flange of the blade , and - a coupling part arranged for being connected to a transport unit , and - attaching a blade spanwise support frame to a spanwise portion of the blade , where - the spanwise support frame includes a cradle-like support part adapted to engage and support a spanwise surface part of the blade , and - where the spanwise support frame is arranged for receiving a first wheel base with at least two axles and four wheels, and - the spanwise support frame includes a cradle-like support part adapted to engage and support a spanwise surface part of the blade , and - where the spanwise support frame is arranged for receiving a first wheel base with at least two axles and four wheels, and - connecting the first wheel base to the spanwise support frame , and - connecting a transport unit to the root support frame , where - the transport unit includes a carrying structure and - at least one second wheel base with at least one axle and two wheels, and - the transport unit includes a carrying structure and - at least one second wheel base with at least one axle and two wheels, and - where the transport unit before being connected to the root support frame , is moved into a position partly underneath the blade root, and where the second wheel base is underneath the blade and the carrying structure is underneath the root support frame , and where the cradle-like support part and/or the root support frame is supported by at least two legs , which are movable between at least a support position and a transport position as well as vice versa, and where movement of the legs is performed manually or using a power source. <EOS>
