The bare machine drop test machine for industrial vacuum cleaners is mainly used to simulate the durability life test of bucket vacuum cleaners in actual use. Lift the upright vacuum cleaner vertically and then freely drop it vertically onto a pine board. By increasing the height of the testing vacuum cleaner within the range of 0-500MM, the electric release mechanism instantly releases the vacuum cleaner that has been raised to a certain height until the brush base falls to the center of the pine board. Periodic tests are conducted through PLC program control. The testing machine has strong universality, simple operation, convenient control, and low failure rate
