The present invention relates to a method of setting a rollover line of a crane and a crane control method using the same. Specifically, an outrigger is taken out, a boom is drawn out in the horizontal direction, the boom is turned at a certain angle, and a pressure value of a derrick cylinder in which rollover does not occur is measured at each turning point. Therefore, it is possible to calibrate the pressure value forming the rollover line according to the method of setting the rollover line of a crane which generates the rollover line of the crane and the length of the outrigger, and prevents rollover of the crane by measuring the pressure value of the derrick cylinder. In the present invention, since the rollover line of the crane is generaged through an actual test, an error occurrence rate is small. Since correction of the pressure value forming the rollover line according to a change of the outrigger length is easy, field response force is good. COPYRIGHT KIPO 2018 ...

... 본 발명은 중량체를 상층부로 운반하는 카고 크레인의 붐대 긴장유지장치에 관한 것으로, 다단으로 접히는 붐대를 최대한 인출시킨 상태에서 붐대의 처짐을 방지하는 와이어를 적은 힘으로 최대한 긴장시킬 수 있도록 한 것이다. 이를 위해, 최선단의 붐대(1)에 일단이 고정된 와이어(2)를 드럼(3)에 감아 펼쳐진 붐대(1)의 긴장을 유지하는 카고 크레인의 붐대 긴장유지장치에 있어서, 드럼(3)의 일 측에 클러치에 의해 동력전달이 이루어지거나. 차단되게 설치되는 래치(4)와, 상기 래치의 일 측에 공회전 가능하게 설치된 회동부재(5)와, 상기 회동부재에 힌지 결합되어 회동부재의 회동 시 래치(4)에 걸려 래치를 회전시키고, 복귀 시에는 래치(4)와의 걸림상태가 해제되는 가동발톱(6)과, 유압펌프의 구동원에 의해 작동하는 유압실린더(9)와, 상기 유압실린더의 로드(9a)와 회동부재(5) 사이에 연결된 링크(10)와, 상기 가동발톱(6)의 반대편에 위치되는 측판(11)에 설치된 래치(4)에 걸려 드럼(3)의 회전된 상태를 유지하는 스토퍼발톱(12)으로 구성된 것을 특징으로 한다.

... 본 발명은 크레인의 전복선 설정 방법 및 이를 이용한 크레인 제어 방법에 관한 것으로서, 특히 아웃트리거를 인출하고, 붐을 수평 방향으로 인출한 후, 붐을 일정 각도로 선회하며, 선회 지점마다 전복이 발생하지 않는 데릭 실린더의 압력 값을 측정함으로써, 크레인의 전복선을 생성하는 크레인의 전복선 설정 방법과 아웃트리거의 인출 길이에 따라, 전복선을 형성하는 압력 값 보정이 가능하고, 데릭 실린더의 압력 값을 측정함으로써 크레인의 전복을 방지하는 크레인의 제어 방법에 관한 것으로, 본 발명은 크레인의 전복선을 실제 테스트를 통해 생성하므로 오차 발생률이 적고, 아웃트리거 길이 변경에 따른 전복선을 형성하는 압력 값 보정이 용이하므로 현장 대응력이 좋은 효과가 있다.
