FACTOR 55 - WHERE CLOSED SYSTEM WINCHING WAS BORN
CLOSED SYSTEM WINCHING™ is a winching technique using rigging comprised entirely of closed link hardware. The non-closable opening of common winch hooks prevent hooks from qualifying as secure closed links. Poorly constructed sheet metal safety latches of hooks do not qualify as a secure means to contain loads and are prone to failure, especially during momentary slack conditions where winch loads often shift and apply high forces to these weak non-structural latches. Hooks often come loose during vehicle recovery operations due to hook safety latch failures. Learn more about Closed System Winching.
