This item provides a means for dynamic testing of a wide range of conventional style linear actuators and screwjacks falling within specified limits set forth capable of exerting, on the unit under test. A force ranging from zero to a maximum of 5000 lbs. in either tension or compression provides for testing units having an O/A maximum LG of 60 , a maximum stroke of 24, a maximum rate of travel of 4 about the longitudinal axis of the loaded column. Test stand is capable of driving screwjacks at a constant rate for each load condition with measured input torques ranging from 0-60 pound inches USAF.
