Does anyone know how it happened? What was he doing, what went wrong?
I crawl under my bus all the time under these circumstances:
1. Parked on a flat, level surface.
2. Parking brake set.
3. Air bags inflated.
4. Leveling jacks down as a safety against airbag failure.
I've never had cause to jack the bus up beyond normal airbag operating
height. I'm small enough I can work around it without lifting it. I
can't see the airbags and the jacks failing at the same time. I'd
imagine most of the danger here is when you've actually lifted one or
more tires off the ground, yes?

What I got from Mike's post is reiteration of redundancy. What you are doing may be OK if you are skinny enough to be OK if both systems fail. Don't allow anyone in the cockpit while you are under there in that configuration. Try crawling under there with the bags down. If you fit the odds are better. I am to big to get under my coach unless it is jacked up except under the engine behind the tag.
Duplicate safety systems is a good idea because failure will most likely happen only once.

Prevost usually do not have leveling jacks due tomonocoque (sp) construction. You cannot have leveling jacks without a frame.Regardless, a coach like a Bluebird with air bags and leveling jacks also needs to be supported with stationary jacks and/or cribbing while you are underneath. I'm extremely sad to hear of yet another death in this fashion. In the BB community less BB drivers have been reportedly killed in road crashes compared to crushings. Think of it.......we couldour deaths by 50% or more if we just listen to the advise that is given nearly once or twice a month.....NEVER GO UNDER YOUR BUS......unless you know what you are doing. That said, if your are ignorant of how to lift a heavy bus it is your responsibilty to contact a heavy equipment companys to learn the safety procedures. Get your bus over to someone who knows or have them come over to your place and demonstrate how to lift your bus.

The HWH jacks are dependent on valves and lines. when you get under
a bus it is most often chasing a failure of some system.
I use 8inch X 10inch X 30inch long wood stacked like lincoln logs
under a section of frame as a landing point for the bus. I dont use
jack stands because if they are strong enough they are too heavy to
posture and too expensive. Jack stands also rely on the bus staying
still in its tracks and not rolling. The wood I use is Gluelam
remnaments. GlueLam is more or less 8 inch if stack plywood. the
plywood is glued in thin sheets of wood and the grains are crossed
NorthSouth to EastWest. The crossed grain keeps the manufactured
gluelam beam from splitting down a natural grain found in a thick
milled tree trunk style beam. I found the glueLam at a greenwaste
recyclincing junkyard near my house.
I am glad Mike notated COD. It is out of respect for JimS that I
plan on taking extra care when I raise my bus, Trucks, tractors and
cars for repair and service.

I haven't had to spend a lot of time under my 77FC35 yet, but I'm already plotting to build a service pit I can park it over.
I've actually considered using my little backhoe to dig a pair of 18 inch wide trenches parallel and the right distance apart for the wheels and about 5 feet deep, then filling them with rebar and concrete. After it all sets up I would use the excavator to dig the dirt out from in between and then pour a concrete floor in the bottom of that. Fence around it for safety and instant service pit
It's probably crazy but it seems doable ...

Ryan,
That is the precise recipe for a disaster. You need to add: 5. Wheels chocked front and back (with adequate chocks!) Two axles preferred. 6. Jack stands, of suitable weight rating, set under the frame members to hold the bus should it come down.
I note that on later models, lowering the jacks causes the suspension to dump automatically. The leveling jacks (on my coach) state right on the control panel, "Not to be used for working under the coach."
The only true safety from being crushed is for something that can not collapse should be placed between the frame and the ground. The air bags can collapse without warning if (for example) you open an air-line on purpose or by accident. The leveling jacks may have a failure (or you may damage a hydraulic line) while you're working under the coach.Â
I note during my recent visit to CCW that the technicians were clever in their use of the leveling jacks to raise the coach for working under it (at one point, putting blocks under the jacks to raise the coach higher then normal). However, they also used very heavy duty jack stands (looked like they could hold 50 tons) to keep the coach from unexpectedly coming down.Â
