Are Motorhomes Designed for hydraulic jack systems

[Jeff one]

I was on site in Hawes I seen a Motorhome on hydraulic levelling jacks,, with all four wheels hanging in midair,,
Looking at the underside, at a distance of course,, each element was taking stresses and strains there not designed for,, or is it me

Oops

All things considered though if the suspension components can handle between 1500kg and 2500kg per corner I don't think the weight of a wheel and tyre is going to harm it, that said if all 4 corners are off the ground either the system or the operator are doing something wrong as far as levelling is concerned.

It's you...story.ends

When changing a wheel, you normally only lift on one jacking point, with levellers you lift with two jacks at a time, either the front pair, the rear pair or two on the same side.

Up to three jacks are used on most occasions as it's rare that you land on a slope which is only in one direction. The fourth jack comes down just to steady the whole gthing,

Not according to Mick at SAP, it's two jacks as I said but the two can operate at different rates from each other.

The jacks should be working in pairs to avoid any twist on the chassis, they might come down at slightly different rates but when one touches the other catches up, the other two then follow.

I have automatic hydraulic levelling jacks. The way they work is:

• They measure the slope which more often not is compound.
• This tells it which jacks to lower and by how much. Usually 3 though on occasions just two.
• The Jacks (usually 3) are deployed until the vehicle is level.
• The fourth jack is dropped to just touch the ground and take a bit of load to steady the van.

My E&P do not operate as you stated, they operate as I stated and given a choice I would believe what I was told by Mick at SAP, he has a bit of experience with the E&P levelling system.

I have watched our levelling system operate and I can confirm that ours come down and level in pairs.

As indeed do ours

Here's an E&P video demonstrating their levelling system, note at 1 minute 20 seconds that the young lady states that the jacks always operate in two's and this is confirmed if the watch the red spots on the controller change to yellow in pairs as the jack deploy as she continues to demonstrate through the rest of the video.

So do my HPC’s as did the MA-VE on my previous motorhome

 

[Andacami]

It’s the hanging suspension looked so flimsy,, mmmmmm

It does when floating in the air

Golsdchmitts must be different then because mine invariably drop 3 legs, then follow up with the 4th one.

OK, maybe I should have said that if you are in manual they will only work as a pair, in auto they may deploy as you say but once they have touched down they should then revert to applying the lift in pairs.

Not so either with mine. In manual I can select any pair or any single leg and deploy it.
