Shelvoke & Drewry

INTAPAK     The 1976 Intapak (for Intermittent Packer) was probably aimed squarely at the Colectomatic, a design popularized by Heil which was sold in England by way of Jack Allen Motor Bodies, Birmingham. Simply put, the hopper was in fact a hinged trough which was raised as the packer blade simultaneously opened rearward. Once fully raised, the packer blade reversed, scraping the refuse from the trough and into the body. In the SD incarnation, the packer panel was operated by externally-mounted cylinders, driving the blade pivot shaft through bell cranks.     This was a short-lived model for SD, and a design which was becoming obsolete by the mid 1970s. Generally, the operating principle was a sound concept, but suffered from a major shortcoming; no refuse could be loaded during the packing cycle. The 'slide-sweep' intermittent loading rear packers (which were starting to dominate America) could be re-loaded before the cycle was even half complete. And of course there was Shelvoke's own Revopak, which chewed-up refuse without interruption and would out-pack its stable mate.     Heil's Colectomatic hinged-hopper packing method was widely copied in the U.S. and Europe over several decades, but by 1976 was on the way out, and would virtually disappear during the 1980s. The Intapak started with the 'N' Series, and just barely made it to the 'P' Series era before it was discontinued, ultimately a case of bad timing as much as any other factor.
