![]() The insulated horseshoe-shape you see is the thin aluminum insulation outer shell. They carry vegetable oils, syrups, and milk and they also carry solvents, lubricants, mild corrosives, etc. MC-307/DOT 407 tankers are usually horseshoe-shaped when viewed from the rear. Low-pressure bulk liquid cargo tanks – MC-307 (DOT-407) Different types of liners including a chlorobutyl rubber liner, or natural rubber lining, or Plasite linings, Chemline lining or Teflon.Average maximum capacity 9,000 gallons however some tanks are built to hold less.There is rollover protection to prevent manholes from opening up on rollover.There is a Fuel Transport Safety Emergency shutoff system on the driver’s side front.The tank is divided into two to five compartments (usually three to four) in some cases, different products may be in different compartments (in most states, mixed loads are not permitted).Ĭontents are NORMALLY petroleum products, however, it could also contain water or milk Newer tanks are aluminum older can be steel.Oval in cross-section, with blunt ends.May contain mild corrosives, but not strong corrosives. May sometimes carry non-flammable liquids (e.g., milk or molasses). Typically carries gasoline (UN/NA 1203), diesel fuel (fuel oil), liquid fuel products, alcohol, and almost any other kind of flammable or combustible liquids.These tankers have one or more domes or hatches and dome covers, generally one hatch per compartment in the tank. The insulated compartment tanks typically come in 3 compartments, 4 compartment, or 5 compartment configurations. MC-306 (MAWP of 3 psi) and DOT 406 (MAWP of 4 psi) tankers are elliptical and typically transport gasoline or other flammable liquids. Non or low-pressure bulk liquid cargo tanks – MC-306 (DOT-406) Fuel transport systems, depots, chemical transport companies, and gas transport companies need safe and reliable tankers to hold that material. Various cargos require different types of tankers to safely get the cargo over the road within the Department of Transportation requirements. (Maybe it needed a Trans Am.) Plus, don't forget about trucker movies White Line Fever and Breaker! Breaker!, the latter starring Chuck Norris.Fuel transport safety is a major concern that any company that moves and distributes fuel is concerned with. We's headin' for bear on I-one-O 'bout a mile outta Shakeytown, I says 'Pigpen, this here's Rubber Duck, and I'm about to put the hammer down.'"Įnglish translation: One June 6 night, three trucks-a Kenworth, a Peterbilt with tilt-cab engine access, and a GMC-were approaching a highway patrol car on Interstate 10 one mile east of Los Angeles, when the Kenworth driver announced on his CB two-way radio to the GMC driver, who had a trailer filled with live hogs, that he was getting ready to speed up.ĭespite all the CB lingo, the film couldn't touch 1977's trucker-themed Smokey and the Bandit, which grossed more than $100 million. Lyrics: "It was the dark of the moon on the sixth of June in a Kenworth pullin' logs, a cab-over Pete with a reefer on, and a Jimmy haulin' hogs. Here's a trucker-to-English translation of one of the song's verses that inspired the movie: McCall, a character he created to promote an Iowa bakery. for a week, written and sung by award-winning ad man Bill Fries under the name C.W. In December 1975, the song "Convoy," on which the movie was loosely based, was the No. Not bad-though that year's top-grossing movie, Animal House, made $141 million. Sam Peckinpah's Convoy grossed about $15 million in 1978 when it came out. Trucks are also beginning to incorporate more composite materials-the same kind of transformation that in aeronautics produced the current set of super-efficient airliners, like the Boeing Dreamliner. “Super single" wide wheels that replace dual wheels are said to improve fuel mileage by up to 7 percent. ![]() How do you make a huge, heavy truck more fuel-efficient? Fairings that hide the leading edge of the trailer, side skirts that prevent wind turbulence under the trailer, and round caps over the rear trailer doors all combine to improve fuel mileage. (That said, it was carrying a heavy load and achieved 178.4 ton-miles per gallon, more than double the national average in the measure that takes payload into account.) This year Shell’s Starship concept truck used advanced aerodynamics and hybrid motors to attain… 8.9 mpg. Going up a steep hill, a truck's mileage might drop to about 2.9 mpg, while going down the same hill will raise it to more than 23 mpg. In 1973, the feds estimated that semis got about 5.6 miles per gallon of diesel, and today’s estimates are still abysmal.
