We could load test all types of boat hoisting cranes using proof load water test weight bags. These cranes are typically located in marinas and shipyards, and used on all docks for every launching and hauling operation. They are frequently used in combination with a vessel lift/storage cradle.
The use of water filled weight bags ensures compliance with regulatory and certifying authority requirements. Initial and periodic proof-load testing of these boat hoisting cranes are requested by internationally recognized standards specified by Det Norske Veritas – Germanischer Lloyd (DNV-GL), American Bureau of Shipping (ABS), Bureau Veritas, Lloyds Register, and others.
The use of water test weight bags for boat hoist and crane load testing is a safe technique for slowly applying the test load. Because it allows technical problems with the crane to be recognized and corrected prior to reaching the full test load. In addition, we could drain the load water without have to lower the test weight. So it would be helpful in situations where the hoisting system or brakes were compromised in some way.
DOOWIN could also supply load cells and water meters upon your request. Crane load cells are calibrated annually to ensure the measured loading on your crane is reported accurately. In addition, our load cells and water meters are sufficiently accurate to allow for calibration of your crane’s load indicating system. It enhances the accuracy of the measured load once the crane is returned to service.
