① Independent Seismic Structure & Space-Saving Design

・Can be installed in existing buildings due to its independent seismic structure frame.

・With Type Approval certification, administrative building permit applications are not required for buildings under 500㎡ (notification may be required by some administrative bodies).

Our proprietary Zip Chain supports the drive mechanism. Two chains mesh to form a single, strong columnar structure, enabling "pushing and pulling."
