The utility model discloses a kind of electric push rod load life testing devices, comprising: rack;Fixed seat is located in the lower part of the rack, for fixing the electric push rod to be measured;At least two horizontal parallel arrangements of sliding load, sequentially arranged in the vertical direction above the electric push rod to be measured;The lowermost sliding load is connected with the output end of the electric push rod to be measured;Guiding mechanism, vertically arranged on the rack, for guiding the sliding load along vertical direction sliding;Barrier, located on the rack or guiding mechanism, for abutting below each layer of sliding load to maintain the spacing between layers;Wherein, the electric push rod to be measured pushes the lowermost sliding load to move up and sequentially triggers the sliding load linkage of adjacent upper layer, forms load stepwise increasing.The utility model has the advantages that: the stepwise increasing of load is realized, the dynamic scene of load layer-by-layer superposition in actual working condition can be simulated, and test result is closer to real application.
