Could it be a Ackermann body/koffer ?? |

Possible, but in the 50ies there were more independent coachbuilders existing than today. |

Mercedes-Benz L 5000 "Deutsche Marken Butter". The body is without the trace of a doubt an Ackermann "Thermos-Koffer". Ackermann had pioneered those before WWII and held the patent until 1972, when it merged with US trailer manufacturer Fruehauf. Only then other makers could legally build their own versions of the "Thermos" design. The "Thermos" design was unique in so far, that it used the airflow while driving to generate the low pressure required for refrigeration (moving air has a lower pressure than still air), hence made do without any externally powered refrigeration aggregate. Since this effect was not available when the vehicle was stationary, the body was heavily insulated. The apparently overengineered, hermetically sealed side access door is indicative of this. The thick insulation layer reduced the load volume, and for this reason alone the system was abandoned and replaced by the 'modern' thermo bodies fitted with an engine to power the refrigeration aggregate. The extra cost of fuel does not outweigh the profit loss the smaller load volume generates. Another perfect example where greed for monetary profit replaces ecological rationality. -- Last edit: 2011-12-18 16:09:06 |
