2 Tons Eco Friendly Hydrostatic Test Bags Shock Absorbing Lightweight Portable
Description
Crane Load Test Water Bags are innovative tools designed for proof load testing of lifting equipment, including cranes, davits, and winches. Made from high-strength PVC or TPU materials, they are lightweight when empty and easy to transport, yet capable of carrying loads from 1 ton to over 100 tons when filled with water. These bags allow gradual load application, ensuring accurate measurements and minimizing stress on the equipment. Their compact storage size, corrosion resistance, and quick setup make them a preferred choice for shipyards, offshore platforms, and construction sites.
( Case: A shipyard in Singapore needed to test a 50-ton overhead
crane. Using traditional solid weights was costly and
time-consuming. Switching to water bags reduced setup time by 60%,
and the test was completed safely in half a day. )
