Abstract: The crane load-test gauge of the instant invention includes an elongate vessel having multiple fluid containing compartments therein. Each compartment has an open top side. A fluid carrying manifold is disposed along the length of the vessel and has a valve mechanism associated with each of the compartments for introducing fluid into the compartment. The manifold has a conventional fire hose connector on the free end thereof. A level adjusting mechanism is provided for adjusting the level of fluid in a compartment. The level adjusting mechanism includes a trim valve for partially emptying a single compartment and a sluice valve for transferring fluid between compartments. A sight gauge is affixed to a side of each compartment in communication with the interior thereof. The sight gauge is operable to indicate a fluid level in its associated compartment.
