Abstract: The present invention relates to an inspection system. The inspection system comprises a base, a boom lifting mechanism provided on the base, and a boom mounting a detector. The boom lifting mechanism includes at least two support arms arranged sequentially. The at least two support arms include a base arm and a distal arm. The base arm is connected to the base, the boom is mounted on the distal arm, the inspection system has a scanning state and a transporting state, and two adjacent support arms of the at least two support arms are rotatably connected so that the height of the boom in the scanning state is different from that in the transporting state. The boom lifting mechanism of the inspection system of the present invention lifts the boom by rotatably connecting two adjacent support arms, and presents less required driving force compared to the lifting of the boom directly in a vertical direction in the prior art. Thus, there is less weight of the driving mechanism for driving the lifting of the boom, so as to reduce the self-weight of the inspection system.

Abstract: A vehicle mounted mobile container or vehicle inspection system, including: a radiation source, a movable vehicle for carrying the inspection system, and a detector arm rack which has a horizontal arm and a vertical arm, a first end of the horizontal arm is connected to the vehicle and a second end thereof is connected to an end of the vertical arm. The horizontal arm and the vertical arm are connected by a pivotal connecting device such that the vertical arm may pivot in a vertical plane, and the horizontal arm and the vertical arm may be retracted in a same horizontal plane. The novel arm rack construction may reduce the space occupied by it on top of the scanning vehicle after the arm rack is stowed so as to reduce the eight of the scanning vehicle under running condition.
