Popular Post Jamaican Bulldog Posted June 13, 2022 Popular Post Share Posted June 13, 2022 (edited) The show was bit smaller than than last year. Maybe due to unset of rain or diesel prices but it was good to see the very last B model there.

Somewhere on here, there is a chart showing the different dimensions of the different models. And, in general, the B50-series will be lighter (GVWR) rated than the B60-series. B70- and B80-series are even heavier. B20- and B30-series are the lightest. Quote "Eagles may soar, but weasels don't get sucked into jet engines."

However, tri-drive on a lighter series truck????, I'm missing the logic there.

Even the frame looked heavier than most B models I have seen. Looked like b81 frame.

Mark T Posted June 13, 2022 Share Posted June 13, 2022 That is a Hendrickson. It was a really busy suspension and in all actuality ??? it didn't articulate very well. Usually if you got that set up it was 3 17,000 pound Timkens . They'd have 6 wide base tires as opposed to duals . It was sometimes used in mixers (or dumps) and B53s were a fairly common choice for a mixer chassis. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69941-the-very-last-b-model-made-seen-at-the-2022-atca-in-bethlehem-ct/#findComment-500143 Share on other sites More sharing options...
james j neiweem Posted June 13, 2022 Share Posted June 13, 2022 If I remember right the B-57 was a heavy speced truck for concrete trucks. Again if I remember right it offered a frame which was the for runner of the DM. I think I remember this info from somewhere on this site.🙂 2 Quote Link to comment https://www.bigmacktrucks.com/topic/69941-the-very-last-b-model-made-seen-at-the-2022-atca-in-bethlehem-ct/#findComment-500144 Share on other sites More sharing options...

I'd say the tri-axle setup was to lower the weight per axle so it didn't sink in soft ground. 3 axles float better than 2. 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

doubleclutchinweasel Posted June 14, 2022 Share Posted June 14, 2022 (edited) One of my books shows a tri-axle B53S. The caption says “Mack introduced the B53S concrete mixer chassis in 1963. This tri-axle version became available that year and incorporated many weight-saving features.” They also show a B576S all-wheel drive mixer. The 50-series seemed targeted at that mixer market, didn’t it? Edited June 14, 2022 by doubleclutchinweasel 2 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

Mark T Posted June 14, 2022 Share Posted June 14, 2022 That Erie Builders truck doesn't look to have any drive for the mixer on the front of it, and the chassis in the first post doesn't either hmmmm Quote Link to comment https://www.bigmacktrucks.com/topic/69941-the-very-last-b-model-made-seen-at-the-2022-atca-in-bethlehem-ct/#findComment-500235 Share on other sites More sharing options...
