The use of water bags for proof load testing wind turbine spreader beams is recognized as a safe technique for slowly applying the test load. In addition, load water can be drained away at a safe distance without having to reposition or lower the test weights.

Hydro-Wates can also provide custom designed rigging arrangements using company owned high capacity load cells, spreader beams, slings and shackles. We stock this equipment in-house to enable rapid mobilization to your job-site. Our load cells are re-calibrated annually to ensure the measured loading on your beam is reported accurately.

Eccentric Spreader Beams for Special Applications

Rigging and equipment configurations for specific projects are reviewed and approved by one or more licensed professional engineers to ensure test objectives are achieved.

In addition to providing personnel to perform onsite rig-up and filling of water bags, we also perform a comprehensive range of engineering and technical services, including:

  • Certification of proof load test results to nationally and internationally recognized standards specified by API, OSHA, ASME, NSTE, IMO and others.
  • Supervision of field work by licensed professional engineers.
  • Rigging design and certification.
