Proof Load Testing Services
Proof load testing of equipment is performed to establish fitness for use. Proof load testing is generally performed prior to initial use, periodically to confirm on-going fitness for use, and also following repairs to critical load carrying components. In addition to cranes, equipment and machines which are typically proof load tested include, lift beams, spreader beams, custom lift frames, slings, custom sling configurations, hoisting frames, derricks, pad-eyes, winch foundations, and other load bearing structures. Hydro-Wates® can provide certification of proof load test results for our proof load testing services using water bags to nationally and internationally recognized standards specified by API, OSHA, ASME, NSTE, IMO and others.
Generally proof load testing is performed at loads in the range of 10% to 25% over the normal working load limit (WLL) of the device being tested. However, in some cases the test load is greater and should always be in accordance with the manufacturer’s recommended practice.

Custom Lift Frames
The handling and lifting of irregular structures, machines or vessels often requires the use of a custom lift frame. These frames are often used only for the structure they’ve been designed for and can be awkward to proof load test. Hydro-Wates® can help by providing technical and engineering support to assist with a custom rigging solution to enable proof load testing in common test machines. Test results are certified by a licensed professional engineer to meet agreed test standards.
Hydro-Wates® provides equipment and services to load test site cranes, building steel work & frames, elevators, ramps, platforms, and other engineered structures. We can perform this work using water bags, solid test weights or specially designed hydraulic machines.
Ship Building & Repair
Repair work performed on shipboard cranes is frequently inspected by proof load testing the crane prior to reinstating it to service. This work is often performed on tight turn around schedules, with no margin for delays due to faulty proof load equipment. For this reason, Hydro-Wates® maintains an extensive inventory of its own water bags, load cells, rigging and pumps. All of this equipment is maintained by our own personnel.
Load testing manufacturing plant cranes is frequently performed following initial installation or following repairs. This work often requires work stoppage in your plant, so getting the load test performed quickly and correctly is critical. For this reason, Hydro-Wates® maintains an extensive inventory of water bags, load cells, rigging and pumps. All of this equipment is maintained by our own personnel.
