HEMTT (Heavy Expanded Mobility Tactical Trailer) Sling Angle for the Double Basket Chain Sling

Abstract

The U.S. Army Defense Ammunition Center and School (USADACS) has be en requested by the Department of the Army, HQ 191st Ordnance Battalion, AEROD-P-MA, APO New York, to evaluate a suggestion. The suggestion covers the use of spreader bars to separate the chain slings, to avoid pallet damage during loading and unloading of the M977 Heavy Expanded Mobility Tactical Trailer (HEMTT). The initial evaluation of the suggestion concluded that spreader bars were unnecessary in avoiding pallet damage if sling angles between 45 degrees and 60 degrees were maintained during material handling operations. Tests conducted regarding pallet stability with the use of spreader bars indicated that no adverse material handling conditions occurred with their use and spreader bars were safe to use if proper design requirements are followed. It was concluded that spreader bars could be used on a voluntary basis to avoid minor pallet damage if desired.
