Pin Load Cell Technology

Onboard Systems is always looking for ways to improve our products and services by harnessing new advances in technologies and processes. In 2009, we launched our game-changing “pin load cell” technology with the Bell 407 Fixed Beam Suspension System. Since then it has become our new standard for Onboard Weighing Systems, and is now in use on a wide variety of cargo hook kits.

Pin Load CellsPin load cells are designed to mount on one side of the hook by replacing the main attach bolt, rather than attaching as a separate link above the hook. This allows for increased ground clearance, easier cable routing and lower weight, while still allowing the pilot to know the exact weight of the load on the cargo hook to maximize load efficiency while reducing airframe stress.

Pin load cells are an exciting advance in load weigh technology that offers many benefits, including:

  • Increased Ground Clearance — Mounts to one side of the hook by replacing the connecting bolt, rather than attaching as a separate link above the hook.
  • Easier Cable Routing — Can be easily routed with the electrical cable.
  • Lower Weight — The pin load cell has a small profile and weighs just a few ounces. Since it replaces the connecting bolt, installing a pin load cell results in a negligible weight gain.
