ABSTRACT:
The grounding tank 2 is laid on its side in the state that the covers 7A and 7B of the openings 3A and 3B at the both ends thereof are removed and the truck 8 is turned so that the side frame 8b on the back of the truck 8 and the bottom 8a with the wheel 11 are reversely positioned so as to mount the divided arrester units 7A and 7B to the tank 2 and the cover 7A (7B) and each arrester unit 4A (4B) are mounted and fixed to the side frame 8Ab, 8Bb so that they can be mounted and removed in the integrated state. The cover 7A (7B) and each arrester unit 4A (4B) are lined up in a horizontal line at the same height as that of the openings 3A and 3B of the grounding tank 2 after the truck 8 is turned and returned to the normal posture. The arrester units 4A and 4B are inserted and set into the grounding tank from side by moving the trucks 8A, 8B and the covers 7A and 7B are removed from the truck 8A, 8B and mounted on the tank 2 side so that they close the openings 3A and 3B at the same time. Thereby, the simplification, labor saving, and safety of arrester assembly are promoted.
