a frame which is installed on a ground surface;

a plurality of height adjustment means which is formed on a top surface of the frame;

a support plate which is disposed on tops of the plurality of height adjustment means;

a second guide rail which is disposed on a top surface of the support plate so as to correspond to a first guide rail formed on a loading part of a transportation means;

a connection means which is disposed at an end of the second guide rail and connects an end of the first guide rail;

a fastening means which is disposed on a front side of the support plate and is coupled to an end of the loading part;

a movable body which is provided with driving rollers on a bottom thereof so that it can move along the first guide rail and the second guide rail and is loaded with cargo on a top thereof;

a drive means which is disposed on a rear side of the support plate so as to move the movable body along the first guide rail and the second guide rail and includes a wire configured to be connected to one side of the movable body, a winding unit configured to wind the wire, and a drive motor configured to drive the winding unit;

a fastening plate which is disposed on the movable body; and

a guide line which is disposed adjacent to the second guide rail so as to be coupled to the fastening plate through a locking member.

2. The cargo loading system of claim 1 , wherein a front side of the second guide rail is formed as an inclined surface which rises gradually.

3. The cargo loading system of claim 1 , wherein the connection means comprises a coupling pin configured to pass through a first through hole formed at an end of the first guide rail and a second through hole formed at one end of the connection body and thus performs fastening, and a coupling pin configured to pass through a third through hole formed at an end of the second guide rail and a fourth through hole formed at a remaining end of the connection body and thus performs fastening.

4. The cargo loading system of claim 1 , wherein the fastening means comprises a fastening ring configured to be attached to an end of the support plate, a first fastening rod configured to be hinged to the fastening ring, a turnbuckle configured such that universal joints are coupled to both ends thereof and one end thereof is coupled to the first fastening rod, and a second fastening rod configured such that a remaining end of the turnbuckle is coupled thereto and a through hole is formed at an end thereof.

5. The cargo loading system of claim 1 , wherein:

the fastening plate is provided with a fastening hole and coupled to a side surface of the movable body via a fastening bolt, and is provided with an elongated hole in a longitudinal direction thereof so that the locking member can be accommodated in the elongated hole;

fastening members protrude from a side surface of the guide line in a predetermined arrangement so as to accommodate the locking member, and a first fastening pin hole configured such that a fastening pin is coupled thereinto is formed through a side surface of each of the fastening members; and

the locking member passes through the elongated hole and the fastening member, a second fastening pin hole corresponding to the first fastening pin hole is formed through a side surface of the locking member, and the fastening pin passes through the holes and thus performs fastening.

6. The cargo loading system of claim 1 , wherein the drive means is configured such that a rotating shaft is disposed adjacent to the first guide rail, a guide shaft is disposed adjacent to the second guide rail, and the wire is connected to one side of the movable body via the guide shaft and the rotating shaft.
