A device for preventing entry into the swing radius of a crane upper revolving structure , characterized in that a safety rope is stretched between the ends of the bar. (2) An intrusion prevention device within the swing radius of a crane upper revolving structure according to claim 1 , wherein the bar is attached to the vehicle body frame so as to be able to rise and fall freely. (3) The bar is an intrusion prevention device within the swing radius of a crane upper revolving structure as set forth in claim 1 of the utility model registration claim, wherein the bar extends and contracts with respect to the vehicle body frame. (4) The device for preventing entry into the swing radius of a crane upper revolving structure according to claim 1 , wherein the bar is detachably attached to the vehicle body frame. (5) An intrusion prevention device within the swing radius of a crane upper revolving structure according to claim 1, wherein the bar has a pin raised at its tip and a ring at the end of the safety rope is hooked to the pin. The brief description of the drawing has been amended as follows. In the first line of page 7 of the specification, the word "boom" is corrected to read "upper revolving structure." In the 16th line of page 6 of the specification, "the turning radius of the crane" is corrected to "the turning radius of the crane upper revolving structure."

Claims

[Scope of Claim for Utility Model Registration] (1) Attach a bar from the crane body frame so that it can protrude outward in four horizontal directions as necessary;
A device for preventing entry into the swing radius of a crane, characterized in that a safety rope is stretched between the ends of the bar. (2) The bar is a device for preventing entry into the swing radius of a crane as set forth in claim 1 of the utility model registration claim, wherein the bar is attached to the vehicle body frame so as to be able to rise and fall freely. (3) The bar is a device for preventing entry into the swing radius of a crane as set forth in claim 1 of the utility model registration claim, which extends and contracts with respect to the vehicle body frame. (4) The bar is a device for preventing entry into the swing radius of a crane as set forth in claim 1 of the utility model registration claim, wherein the bar is detachably attached to the vehicle body frame. (5) A device for preventing entry into the swing radius of a crane as set forth in claim 1 of the utility model registration claim, wherein the bar has a pin raised at its tip, and a wheel at the end of the safety rope is hooked to this pin.
