The present invention relates to an expandable bucket safety handrail structure mounted on an aerial work vehicle. The bucket, which has a form connecting front and rear and left and right boundaries of an aerial work board, installed in an end part of a boom forming an aerial work device to allow a worker to board on to prevent falling of the worker and changing a size of a work space where the worker is positioned while the bucket is not separated, thereby enabling changing of a position of a safety handrail.
본 발명은 고소작업장치를 구성하는 붐(Boom)의 단부에 설치되어 작업자가 탑승하는 버켓, 즉 고소작업대의 전후 및 좌우 경계를 연결하는 형태로 구성되어 작업자의 추락을 방지하되, 탈거가 이루어지지 않는 상태에서 작업자가 위치하는 작업공간의 크기 변경 및 이에 따른 안전난간의 위치변경이 가능한 고소작업차량 탑재 확장형 버켓 안전난간 구조체에 관한 것이다.
