An objective of the present invention is to easily install an emergency escape device. According to the present invention, a worktable weight sensing structure of a high place work vehicle for rescue and firefighting comprises: a worktable boom link to support a worktable on which a heavy object is mounted among a plurality of boom links making up a boom of a high place work vehicle; a connection boom link directly bound to the worktable boom link; a cylindrical load cell arranged at a binding point between the worktable boom link and the connection boom link to carry out load recognition by vertical force; and a boom link connection rod to rotatably couple the worktable boom link, the connection boom link, and the cylindrical load cell to each other. A load of a heavy object placed on the worktable vertically acts on the cylindrical load cell through the connection structure between the worktable boom link and the boom link connection rod to carry out load recognition for the heavy object.

    본 발명에 따른 구난 소방용 고소작업차의 작업대 중량 감지 구조는, 고소작업차의 붐대를 이루는 복수의 붐링크들 중 중량물이 거치되는 작업대를 지지하는 작업대 붐링크; 상기 작업대 붐링크와 직접 결속되는 연결 붐링크; 상기 작업대 붐링크와 연결 붐링크 간의 결속 지점 상에 배치되어 수직력에 의한 하중 인식을 시행하는 원통형 로드셀; 및 상기 작업대 붐링크, 연결 붐링크 및 원통형 로드셀을 상호 회동 가능하게 결합하는 붐링크 연결봉;을 포함하고, 상기 작업대에 놓인 중량물의 하중은 상기 작업대 붐링크 및 붐링크 연결봉 간의 연결 구조를 통하여 상기 원통형 로드셀 상에 수직 방향으로 작용하게 하여 중량물에 대한 하중 인식을 시행한다.
