Colectomatic This was the Heil's first true rear load packer, and the first truck to bear the famous Colectomatic moniker. Introduced around 1954, it was modern in every respect but particularly in its clean and modern lines. Inside, the mechanism was somewhat complex, using only two hydraulic cylinders to: (a) raise the hopper bucket, (b) pivot the packer panel and (c) raise the tailgate assembly when discharging. If you look carefully, you can see one of the "lost motion" links connected to the packer panel. 8/2/04 © 2004 Eric Voytko All Rights Reserved Photos from factory brochures/advertisements except as noted Logos shown are the trademarks of respective manufacturers
