연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Disclosed herein is an apparatus preferably coupled to a boom on a truck, the apparatus capable of a plurality of configurations for a variety of uses. In one configuration, the apparatus can perform rapid semi-precise cutting of vegetation. In another configuration, the apparatus can perform more precise trimming of one or more areas (e.g., limbs) and optionally use a limb clamp to prevent cut limbs/vegetation from arbitrarily falling on objects below the cutting area. In yet another configuration, the apparatus can have a grapple or similar device attached to the end of the boom for use in relocating debris or for loading debris into a removal facility such as dump or garbage truck. In each configuration, the apparatus comprises one or more rotatable or pivoting couplings to allow for rotation about one or more axis and therefore allow precise manipulation from an operator in the vehicle or on the ground.
