homemade electric leveling system

DaveVA78Chieftain · October 23, 2016, 09:53 AM

QuoteI don't want to hijack this thread but I was wondering if we have anything on the HWH 110 leveling system. Specifically an older system as I just found one on an old Classic 1975 Brave. I someone said it was a 110. She's looking pretty tough but I thought it might be worth trying to bring it back to life. Any help of direction would be very much appreciated.

You have to go to the web archive to find 110 info. HWH normally manages things separately (controller, pump, jack, etc.) so you have to ID which elements you have in order to find the info.

LOts of good info in the training area also.

Because the web archive is a snap shot of data at a given date, you some times have to go to different dates to find the info you are looking for.

Also not wanting to hijack (pun intended), I have the HWH 100 system and it's pretty much the same as the 110 just different controller (nothing more than a hydraulic valve body), Are you talking about getting the motorhome, or it's jack system?

Brians1969: Sweet. What is the rated load of that jack?

Just getting the leveling system. I retrieved some of it all ready. Got all the hoses and I believe the pump. I still have to go back and get the legs. But I'm not sure about the electrics. In just what I should be looking for to retrieve.

Apparently HWH finished updating their site: http://www.hwhcorp.com/ml54800_generic.html

Wow great score guys. Thanks Dave and Dan

Wow, nice score! HWH is nice but pricey!
Capn: 7,500 lbs. per jack

Yeah! Pretty excited. Thinking I'm getting a little over my head with some of this stuff but then who of us aren't. D:oH!

Brians1969 At 7500 per jack that may work. The idea been pointed out that you are just putting feet on the ground to stabilize, not really lift the coach off the ground.

brians1969 · October 25, 2016, 12:33 PM

No, these are not stabilizing jacks. These are leveling jacks. There is a a difference.
At a total of 30,000 lbs of capacity, it can lift the motorhome with it's twin on it's back and still have left over capacity.

Stabilizing jacks are those $50 BAL scissor arrangements that go on your bumper.

Although Atwood (and probably the others) recommend that you do not lift the wheels off the ground.

Lifting is one thing, keeping things from bending once the tires leave the ground is totally different.

TerryH · October 25, 2016, 10:45 PM

And regardless of the system, it is NOT rated for working underneath the vehicle. Use it for levelling, use it for stability, but NOT for under vehicle maintenance.
