The PDT 700 facilitates precision drop testing of large test items weighing up to 1540 lbs. (700 kg). Similar to the PDT 300 design, the larger PDT 700 utilizes a welded steel drop carriage, guided by precision bearing assemblies on a structural steel guide beam. A hoist system raises and lowers the drop carriage to easily and safely move heavy test items. The drop carriage is pulled downward during a drop test, allowing the test item to free fall. When the drop carriage descends into slots below the impact surface, a hydraulic damper and elastomer strips at the bottom of the slots prevent rebound of the drop carriage into the test item.
