Abstract
Description
Claims (2)
- 현수하중 스윙변위 검출기에 있어서, 로프등에 의하여 현수하중을 매다는 크레인에서 트롤리와 현수하중 사이의 상대변위를 검출하기 위한 스윙변위 검출기와; 트롤리를 지지하는 크레인 상부 구조체의 지면으로부터의 변위를 검출하기 위한 크레인 상부구조체 변위 검출기와; 스윙변위 검출기에 의한 현수하중 변위의 측정값 및 크레인 상부 구조체 변위 검출기에 의한 크레인 상부 구조체 변위의 측정값을 인풋으로써 수용하기 위한, 그리고 현수하중 변위의 측정값과 크레인 상부구조체 변위의 측정값 사이의 차에 기초하여 현수하중 변위의 측정값을 보정하기 위한 연산수단;을 포함하는 것을 특징으로 하는 현수하중 스윙 변위검출기.
- 제 1 항에 있어서, 연산수단에 의하여 보정된 현수하중 변위의 측정값은 크레인 상부구조체의 진동과 관련된 짧은 주기의 웨이브 요소로부터 영향받지 않으며, 로프등의 진동과 관련된 긴 주기의 웨이브 요소만으로 구성되는 것을 특징으로 하는 현수하중 스윙 변위검출기.
