Popular Post Whiskymack Posted June 18, 2015 Popular Post Share Posted June 18, 2015 Just wondered if anyone knows anything about these trucks. It seems like they had a few of them including early steel dash models. Would they have came from the factory with the lift axle? I can't say I've seen any 70's era pictures of trucks with lift axles so I thought maybe they got added later. 6 Quote Link to comment https://www.bigmacktrucks.com/topic/40550-puget-sound-western-rs/ Share on other sites More sharing options...
TeamsterGrrrl Posted June 18, 2015 Share Posted June 18, 2015 Those mid mounted lift axles are pretty common in Washington, Orgeon, etc.- They can run at 105,500 pounds weight instead of the usual 50 state limit of 80,000 there. But they still have to meet a "bridge formula", which usually requires 8 axles and they have to be spaced far apart, thus the extra axle mounted so far forward of the drive axles. This would typically be coupled to a 4 axle trailer to get near the maximum weight allowed. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/40550-puget-sound-western-rs/#findComment-293835 Share on other sites More sharing options...
slpwlker Posted June 20, 2015 Share Posted June 20, 2015 The same weight in Washington can be done on 7 axles, Oregon is 2k Less an axle ergo 8 axles. Was told 12 steer, 12 lift, 34 tandem, 34 trailer and think it was 12 per axle or somewhere in that ball park to 105500 Quote Link to comment https://www.bigmacktrucks.com/topic/40550-puget-sound-western-rs/#findComment-294016 Share on other sites More sharing options...
TeamsterGrrrl Posted June 20, 2015 Share Posted June 20, 2015 It's all based on bridge formula, you can do 105,500 on 7 axles if you can get them spaced far enough apart.

Whiskymack Posted June 20, 2015 Author Share Posted June 20, 2015 Do you know when they started using lift axles in Washington? Would it have been 1970's or later than that?

gearhead204 Posted June 20, 2015 Share Posted June 20, 2015 lift axles became popular starting in the late 80's.
