High Capacity Proof-Load Test Packages
Hydro-Wates© offers a range of services and a complete line of high-capacity water bags for performing periodic proof load tests on cranes, winches, pad-eyes, bridges, and various load-bearing systems. Water bags with up to 35 metric ton capacity can be used individually or in groups to perform load tests with virtually no weight limit.
Offshore Applications
Each water bag is shipped in its own aluminum offshore storage/transport container to prevent damage in transit and to ensure that the equipment arrives at your work site ready to use. Each container is equipped with a 35 metric ton water bag and all necessary hoses and fittings.
Using the firewater or washdown water supply, a single 35 Tonne water bag can be filled in 15 – 20 minutes and drained in the same amount of time.
If requested, water metering systems are available to provide a secondary means of determining the weight of the proof load.
Load Monitoring
Hydro-Wates© also provides digital load cells and electronic displays for use with its water bag packages. Standard load cell transducers are available from 12 tonne to 120 tonne capacity, with capacities up to 1,500 tonnes available on request.
Each load cell package comes complete with capacity matched shackles, master links and a load certified aluminum tool box. The standard measurement units on load cell displays are metric tons, short tons, kilograms and pounds. Each display is equipped with a data logging system, to enable lift records to be downloaded to a notebook computer using the data link provided.
Hydro-Wates© uses Crosby® shackles and rigging hardware in all of its test packages, and has standardized on the Crosby product line to ensure dimensional and strength compatibility with all of our equipment. Proof-load and design conformance certificates are available upon request.
