Zero drop test machine is mainly used for drop test of larger packages. Zero drop test machine has an "E" type fork that can move downward quickly as the test piece bracket, and the tested goods are placed and balanced according to the test requirements (face, edge and corner test). During the test, the pallet moves downward at high speed and separates from the test piece. Before the tested packaged goods fall to the bottom plate, the "E" type fork has been embedded in the bottom plate under the action of the high-efficiency shock absorber. In theory, the zero drop test machine can perform drop tests from zero height range.
