This block features a ball bearing for stabler sheave rotation compared to our existing snatch blocks that use bushing (AK Snatch Block Type Ⅲ-A). The hook type snatch enables smooth rope insertion and extraction. Additionally, the new hook design is shaped to be easy to handle with fingers, which allows for quick opening and closing and helps improve work efficiency. The hook and the body each have a hole through which a wire can be threaded, to fix the hook to the body and prevent accidental release.
