Section III. PRINCIPLES OF OPERATION
1-11. SYSTEM TECHNICAL PRINCIPLES OF OPERATION.
The 500 gallon drum is a collapsible container for storing and transport liquid fuel. Materials used for the drum
body are designed to allow handling, filling and emptying at temperatures from -60°F to +95°F (-50.6°C to +35.28°C) The
body is reinforced with polyester cord to withstand the stresses of handling and delivery. End to end drum stresses are
limited by internal cables between the end plates. The fuel connections are quick d adapters, one at each end of the
drum. The adapter is of the dry type. which seals the connection when disconnected, preventing fuel spillage. The
adapters are covered with protective caps when not in use.
Drum filling is by a pump to a safe internal pressure. The drum expands as it fills, and collapses as it is emptying.
A filled drum can be lifted or towed on smooth terrain speeds not to exceed 10 mph (16km/hr) as a wheel. For these
purposes a yoke assembly is fastened to both ends of the drum and to the lifting or towing device.
