a second moving device disposed at an upper end of the first moving device and operable to move the blade fixing frame in a width direction of the base;
a third moving device disposed at the upper end of the base;
a fourth moving device disposed at an upper end of the third moving device; and
a balance block spaced apart from the blade fixing frame and disposed on the base, the balance block configured to be moved by the third moving device in the longitudinal direction of the base and configured to be moved by the fourth moving device in the width direction of the base.

2. The blade transport vehicle according to claim 1 , wherein the first moving device includes:
a first guide rail disposed at the upper end of the base and arranged in the longitudinal direction;
a first plate coupled to the first guide rail; and
a first drive unit operable to move the first plate, the first drive unit being disposed at the upper end of the base and coupled to an end of the first plate.

3. The blade transport vehicle according to claim 2 , wherein the first drive unit includes a hydraulic cylinder.

4. The blade transport vehicle according to claim 2 , wherein the second moving device includes:
a second guide rail disposed at an upper end of the first plate and arranged in the width direction of the base;
a second plate coupled to the second guide rail to support the blade fixing frame; and
a second drive unit operable to move the second plate, the second drive unit being disposed at an upper end of the second plate.

5. The blade transport vehicle according to claim 4 , wherein the second drive unit includes a hydraulic cylinder.

6. The blade transport vehicle according to claim 1 , wherein the third moving device includes:
a third guide rail disposed at the upper end of the base and arranged in the longitudinal direction;
a third plate coupled to the third guide rail; and
a third drive unit operable to move the third plate, the third drive unit being disposed at the upper end of the base and coupled to one end of the third plate.

7. The blade transport vehicle according to claim 6 , wherein the fourth moving device includes:
a fourth guide rail disposed at an upper end of the third plate and arranged in the width direction of the base;
a fourth plate coupled to the fourth guide rail to support the balance block; and
a fourth drive unit operable to move the fourth plate, the fourth drive unit being disposed at an upper end of the fourth plate.

8. A blade transport vehicle, comprising:
a lower trailer;
a base disposed at an upper end of the lower trailer;
a blade fixing frame disposed on the base, the blade fixing frame configured to be moved in a longitudinal direction of the base and in a width direction of the base;
a first moving device disposed at an upper end of the base;
a second moving device disposed at an upper end of the first moving device; and
a balance block spaced apart from the blade fixing frame and disposed on the base, the balance block configured to be moved by the first moving device in the longitudinal direction of the base and configured to be moved by the second moving device in the width direction of the base.

9. The blade transport vehicle according to claim 8 , further comprising a third moving device disposed at an upper end of the base and operable to move the blade fixing frame in the longitudinal direction of the base, the third moving device including:
a first guide rail disposed at the upper end of the base and arranged in the longitudinal direction;
a first plate coupled to the first guide rail; and
a first drive unit operable to move the first plate, the first drive unit being disposed at the upper end of the base and coupled to an end of the first plate.

10. The blade transport vehicle according to claim 9 , further comprising a fourth moving device disposed at an upper end of the third moving device and operable to move the blade fixing frame in the width direction of the base, the fourth moving device including:
a second guide rail disposed at an upper end of the first plate and arranged in the width direction of the base;
a second plate coupled to the second guide rail to support the blade fixing frame; and
a second drive unit operable to move the second plate, the second drive unit being disposed at an upper end of the second plate.

11. The blade transport vehicle according to claim 8 , wherein the first moving device comprises:
a first guide rail disposed at the upper end of the base and arranged in the longitudinal direction;
a first plate coupled to the first guide rail; and
a first drive unit operable to move the first plate, the first drive unit being disposed at the upper end of the base and coupled to one end of the first plate.

12. The blade transport vehicle according to claim 11 , wherein the second moving device comprises:
a second guide rail disposed at an upper end of the first plate and arranged in the width direction of the base;
a second plate coupled to the second guide rail to support the balance block; and
a second drive unit operable to move the second plate, the second drive unit being disposed at an upper end of the second plate.

13. A vehicle for transporting a blade, the vehicle comprising:
a lower trailer;
a base disposed at an upper end of the lower trailer;
a first moving device disposed at an upper end of the base;
a second moving device disposed at an upper end of the first moving device; and
a balance block disposed on the base and configured to be moved by the first moving device in a longitudinal direction of the base and configured to be moved by the second moving device in a width direction of the base.

14. The vehicle according to claim 13 ,
wherein the balance block includes a weight, and
wherein the first and second moving devices are configured to move the weight of the balance block to prevent the vehicle from overturning by performing a balance function in correspondence to a weight of the blade.

15. The vehicle according to claim 13 , further comprising:
a blade fixing frame disposed on the base; and
a third moving device disposed at the upper end of the base and operable to move the blade fixing frame in the longitudinal direction of the base,
wherein the balance block is spaced apart from the blade fixing frame in the longitudinal direction of the base.

16. The vehicle according to claim 15 ,
wherein the balance block is disposed at a position rearward of the blade fixing frame, and
