5000 Ton Device The largest Statnamic device available can provide a test load of 5000 tons shown below. This device is encompassed by a modular containment structure that is the basis for catching the reaction mass after the Statnamic load test. The annular space between the reaction masses and the containment cell is filled with readily available gravel as shown in the cross section below. When the masses are propelled upward, the gravel simply fills the void created under the masses, thus catching the 150 ton mass. The gravel catch system is fairly low tech but it is an economical means of catching 150 tons in mid-air. In addition, the gravel can be reused after the test for many other things on a construction site. Set up time for this test device has been streamlined by heavy repetition. As with the smaller Statnamic devices, the goal is to construct a mechanical catch system for the 5000 ton Statnamic device as well.
