Armored Crawler Tractor and Rake Rail Transportability and Tiedown Provision PullTests

摘要

The U. S. Army Defense Ammunition Center and School (USADACS), ValidationEngineering Division (SMCAC-DEV), was tasked by the U.S. Army Tank-Automotive Command, AMSTA-UED, to perform rail transportability and tiedown provision pull tests on the T-9 MCAP armored crawler tractor and rake. The armored crawler tractor with blade attached and demountable rake on pallet were tested 13-14 July 1993. The tractor and rake were cabled to a flatcar for rail transportability testing. No damage was sustained by the tractor or rake. Pull testing was not completed due to sharp edges in the armor on the roof of the tractor. The sharp cutting edges severed or damaged the wire rope cables used to perform the Pull tests. Since these cables were cut, the edges on the tractor were considered a safety hazard when trying to sling the tractor; therefore, the pull test failed. The rake was not pull tested as it did not have any clearly identified tiedown provisions as required by MIL-STD-209H, Military Standard Slinging and Tiedown Provisions for Lifting and Tying Down Military Equipment.
