hydrostaic V torque

[aidank]

hi,

looking for some guidance/opinions/experience on hydrostaic wheel loaders sub 100hp.

It seems that nearly all the new wheel loaders sub 100hp less than 10yrs old have a hyrostatic drive rather than the conventional torque. I have been told that this hydrostaic drive is not as robust as the torque.

I am interesting in getting a loader for farm work, and thus would need it for clamping silage, and be able to get in and out of small spaces hence sub 100hp, thus it would need to be able to climb rather steep pit faces all day without the oil getting hot hence my quesiton about the robustness of these hydrostaic systems. This would be a lot tougher work than loading gravel in a quarry all day as there would be plenty pushing and shoving as well. Currently people do this work with 15-20yr old jcbs 410s 410Ms 412s also CAT 910s 916s thus I know the torque systems are up to this, these are getting old hence I hope to get something a bit newer.

Also how many hours are are both torque and hydro systems suitable for, I have heard of torque systems going for 10-15k hrs if you change the oil, not so sure about the hydro yet.

anyone ever worked with/designed any of these hydrostatic transmission systems

all comments welcome
thanks,

Put a temperature gauge on the hydraulic system if it doesn't have one already, and watch the temperature while you are breaking it in. If it gets too hot for your taste, add an oil cooler.

Oil coolers may be available as an option; if so, I'd order one just for fun, given the duty cycle you anticipate.
