Periodical Safety Proof Load Testing

Periodical proof tests are performed to lifting equipment (hoists, winches, cranes, shackles, hooks, etc.) and load bearing structures (gantries, anchor points, etc.) to ensure that they perform to their specifications, as well as to required standards and regulations.

An initial safety proof load test is normally required upon installation of new equipment prior to it being brought into service.

A proof load test should check the devices and structures under more stringent conditions than normal

The proof test help to prevent a failure of the device or structure as such a failure might result in an accident.

Ron dynamometers and load links are especially suitable for proof load tests thanks to their following features:

  • Low headroom loss
  • High Portability
  • Peak hold
  • RS-232
  • Data logger
  • High quality aerospace steel
  • Fatigue rated load cells
  • Extremely long battery life
