Abstract:

The study investigated how well manpower normally available in the field could operate the control levers of a rapid tactical mine-planting system. The subjects, who were selected to represent a normal range of arm strength, operated a control lever at force levels of 60, 80, and 100 pounds while standing on a mock-up of the mine-planters control lever platform. The subjects were able to complete the lever push-pull cycle within a two-second time limit at force levels of 60 and 80 pounds. When the force was increased to 100 pounds, they took 3 12 seconds to complete the cycle. The time to complete a cycle at 100 pounds grew longer as the one-hour test period continued, but there was no such decrement at 60 and 80 pounds. Arm strength in the seated position, as measured by a push-pull gauge, did not reliably predict performance at the lever-throwing task.
