The U. S. Army Defense Ammunition Center and School USADACS, Validation Engineering Division SMCAC-DEV, was tasked by the U. S. Army Tank- Automotive Command to rail impact test per MIL-STD-810D, Military Standard Environmental Test Methods and Engineering Guidelines, the rotary towed sweeper, manufactured by M-B Company, Incorporated, New Holstein, WI. Two MIL-STD-810D rail impact tests were performed on the rotary towed sweeper. While tying down the rotary towed sweeper for the first test, the forward tiedown provision bent. This was a failure of the provision. The sweeper was sent back to the factory and returned to USADACS on 20 August 1990 for retesting. The sweeper was tied to a flatcar with wire rope and subjected to 4, 6, and 8 mph impacts in one direction, and then the flatcar was turned 180 degrees and singly impacted at 8 mph. Cable tensions were monitored during this test. Tiedown provisions were also statically loaded to verify conformance with MIL-STD-209G, Military Standard Slinging and Tiedown Provisions for Lifting and Tying Down Military Equipment. Results of these tests are included in this report. The rotary towed sweeper passed all rail impact tests.
