CLOSED SYSTEM WINCHING™

CLOSED SYSTEM WINCHING™

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.

The elimination of the winch hook and the subsequent substitution to a Factor 55 ProLink, FlatLink, or UltraHook shackle mount and commonly found screw pin shackles/D-Rings does qualify as CLOSED SYSTEM winch tackle.  Once a shackle screw pin is installed, the common screw pin shackle becomes a continuous closed link that securely contains the winch load until the pin is unscrewed and removed.

The ProLink, FlatLink, and UltraHook patented winch shackle mount products by Factor 55 address this winch safety issue by providing a secure screw pin shackle mounting interface to all steel winch cables and synthetic winch ropes.  The Factor 55 unique double shear pin design provides a simple trouble free method of attaching existing cable and rope eyes to the ProLink, FlatLink, and UltraHook products.  Installation requires only minutes.   Once installed, the ProLink/Flatlink/UltraHook products provide a precision mounting hole for screw pin shackles and also provide a large  rubber protected flat surface to cushion against all fairlead mounting surfaces.

Whether the winch line is in tension or a dangerous momentary slack condition, CLOSED SYSTEM WINCHING™ keeps all winch tackle secure and is by far the safest method of operating your vehicle recovery winch.

Hook or Shackle?

Smart off roaders have known for years that the most secure way to use your recovery winch is replace the hook with a common screw pin shackle. Unless you are competing, the added seconds required to use a shackle versus a hook during a vehicle recovery is not worth the safety risk associated with standard winch hooks.

Factor 55 Methods

Factor 55 products are designed and manufactured using state of the art technologies. All of our products are designed using SolidWorks CAD systems and stress analyzed using COSMOS Finite Element Simulation software. The FEA results allow us to optimize a design concept by adding or removing material or changing material properties where necessary.

What is FEA?

FEA or Finite Element Analysis, is a mathematical method of determining stresses in materials before actually building a physical prototype. This allows our engineers to optimize our product designs for the greatest strength to weight considerations. In other words, we can remove material where it is not needed and add material to any weak zones of a particular design concept. This method of design takes away the guess work on determining how thick or what material something should be made of.
