The left connector is installed with two horizontally spaced rectangular plates facing each other and is spaced apart from each other, and the two lower plates are provided with a hook ring, and the right connector has only one rectangular plate with horizontally perforated holes in the center. It is installed and the hook is formed on the lower surface of the plate. In addition, the left and right engaging ring is coupled to form a connector, the engaging groove of the connector is coupled to the lower end of the main body with the groove in the downward direction, the connecting pin having a cylindrical shape is inserted into the coupling hole formed in the connector and the main body It is fixed. (Refer to Fig. 14, the fastening hole is formed in the front and rear of the connector.) In addition, the flange engaging grooves present at both upper ends of the connecting pins have end plates for fixing the main body on both sides, and bolts and nuts. Final fixed coupling.

Coupling method of Example 1 as described above is that the connecting pin is inserted into the fall prevention device in the traveling direction of the crane, so that the transverse rocking motion of the fall prevention device when the crane travels (left and right movements based on FIG. 14). The range of angular range of motion is increased, thereby increasing the stability of the crane by not having rigidity against the rails and being flexible. (The crane travels left and right when referring to Fig. 2, and the crane travels forward and backward when referring to Fig. 14.)

     17, 18, 19, 22, and 23, the coupling method of the crane fall prevention device in the case 2, the left and right connectors are combined to form one complete connector. The left connector is a horizontal hole is drilled in the center, the engaging projection is formed on one side, the left hook is formed at the bottom, the horizontal hole is punched in the center of the right connector, the coupling groove corresponding to the engaging projection is formed on one surface The right hook is formed at the bottom. In addition, the engaging ring of the left and right connectors is combined to form a locking groove. In addition, the locking groove is seated in the lower end of the main body with the groove in the downward direction, and the connecting pin having a cylindrical shape in the coupling hole formed in the connector and the main body is hinged by being inserted into the connector. (Refer to Fig. 17, the fastening hole is formed to the left and right of the connector.) In addition, the flange engaging grooves present at both upper ends of the connecting pins have end plates for fixing the main body on both sides, and bolts and End plate and connecting pin are finally fixed with nut.
