However, in order to meet the requirement of wind power generation, a wind power blade with a shifted center of gravity appears on the market, and even a blade body with a shifted center of gravity of the wind power blade, such as the wind power blade with a curved tip as shown in fig. 2, the center of gravity of such a wind power blade is shifted toward the curved direction of the tip. When this kind of wind-powered electricity generation blade was installed on bearing device 100, its apex can neither set up, also can not set up towards ground because there is the limit for height highway section on some highway sections, if install wind-powered electricity generation blade's apex up, caused the superelevation too late easily when crossing those limit for height highway sections. In order to safely drive at a height-limited road section and reduce the gravity center of the wind power blade lifting truck, the truck body of the wind power blade lifting truck is generally designed towards the direction as short as possible, and if the blade tip is arranged towards the ground, the blade tip is easily contacted with the ground, and the blade tip is easily damaged. Therefore, when the wind turbine blade with the bent tip is encountered, the most reliable installation manner is to arrange the tip of the wind turbine blade to face left or right, that is, in the transverse direction of the carrying device 100.
