very good

1st one is a Wabco 333FT all hyd apart from elevator motors there elec

lot of the comments i have read no nothing about this machine,trans is a allison,steering electric over hydraulic,elevator motors electric,only one rev to load them full otherwise you trip the elevator motors out,le tourneau invention i used to operate for stevensons in kopuku that was a long time ago thanks you guys for the video enjoyed watching.

where did ur boss buy the 333ft from there were 2 running in the coal mine in huntly back in the 70s,these are 657 size scrapers,operated one of these in south australia back in the 80s,no need to heel toe the loud petal like a cat,great machine these babies the one i had was stokin 550hp each V12 detroit and i was loading against all cats last one in the cut first one out by the end of the 12hrs i was up 20 or more loads

don't you mean Wabco scrapers?? and what a rare sight they are! the last time I saw one was on a site development back in 1977 I was only 11 then!!

That's a nice Hydrostat machine.

@Nickael7 I don't think Wabcos were hydrostatic. They had a transmission with gears. But the later self-loading versions had some kind of special loading range that would help you to not spin the tires in the cut.

@wailnshred Hydrostats are so advanced in these days, that you can't have a "floating wheel" -if it get stucked- like in some mechanical transmission with differentials -a simple example-. The hydrostats transm. delivers you more power to ratio than a mechanical one, plus you have the advantage to control the speed and torque as please "infinitely". The CAT versions use it widely. I LOVE HYDROSTATIC TRANSMISSION, they're so fucking powerful and compact.

@Nickael7 I have never seen any scraper with a hydrostatic trans, and I have run quite a few, including at least one Wabco. And, unfortunately they stopped making Wabcos in 1981 or so.

@wailnshred Why they wouldn't use this advance system ?

Nickael7 10 months ago

@Nickael7 Because they stopped making them 30 years ago. The later model Wabco self-loaders like the one in the video did have some kind of special loading range, I think it varied the speed through the torque converter, so when it was in loading range, I think it was kind of like hydrostatic. But it still had a regular transmission with gears.

@wailnshred I see, but is this a mechanical torque converter or a hydrodynamic torque converter ?

Nickael7 10 months ago

@Nickael7 I don't know, not familiar with those terms. The torque converter used in scrapers is between the engine and transmission, it uses hydraulic fluid to transmit power. The first self propelled scrapers didn't even have those, they had a clutch.

@pitbullman1995 Wouldn't have a clue. I live in New Zealand so have no idea but I guess you could start by asking a local road construction crew who might be able to point you into the right direction.
