I like this statement. It makes good sense, and I'll change my procedures to follow it. -Ryan Sad Safety Reminder - Michael - 06-09-2008 10:29 Very Sad Reminder... I've had my bus fall on me twice in the last 20 years. To date I've only received a headache and a bruised ego. During the conversion process on my '63 Bluebird I had to get underneath it often to mount generator, holding tanks, wiring, etc.. but this also applies to our Wanderlodges too. Because I followed the redudant rule, I'm still here to tell you about it. The first was using block to raise the bus.. I had stacked the block with plywood separaters. My old bus was light at only 22,000 lbs but it crushes blocks very easily. I then used only lumber but then found that 4x4's split very easily too. Now I support with large timber and jacks only. However, here's a good start. I took 4-2x6's and laid them flat on a 1'x2' piece of plywood with about 1/2" space between. I then added a second piece of plywook and criss-crossed the 2x6's with the first row. I repeated this pattern until I had aobut 7" high 1'x2' pads for the front wheels, and 7" high 2'x4' pads for the rears. I used glue and screws to help hold it all together. I will drive up on these pads so that my total clearance is the bus clearance plus 7". On that bus it was enough so that if something should fail the bus height would be great enough for me to crawl out and clean my shorts. Now with my Wanderlodge anytime I have to raise the bus I'll treat it as if I was going to work on the hydraulics. Never rely on the hydraulics for human safety, they were chosen to level a bus. There are no safety pins and lines do burst. My pads cost about $100 in material and that is very cheap insurance. If anyone would like pics let me know... These things can happen so fast.. it just takes one small oversite...

I may be wrong but I think their is an issue of the air bags being strained beyond thier extension limits. Don't get me wrong I've had the wheels off the ground via the jacks several times, but I don't like to do it and I think it could easily damage the coach. I would suggest a pit or a lift for the safest way for working under anything. Sometimes we take safty for granted, we think we know what what were doing, most of us have spent a lot of time working on our coaches and we know them intimatly. She can and will bite, if you don't mind her. You just can't be too careful.

This might sound dumb but what about us guys out here that don't have air bags or jacks to level out the coach, can our coach bit us also? I know when I do go under my coach I make sure the brakes are on and something in front or back of the tires. But the only way my coach could fall down and pin me under would haft to be a blown out tire. Our old buses you haft to bleed the excess moisture out of the air tanks every so often and so we do haft to go underneath. > > > > > > > > > > > > > ------------------------------------------------------------------ ------ > > > > No virus found in this incoming message. > > Checked by AVG. > > Version: 7.5.524 / Virus Database: 270.0.0/1490 - Release Date: 6/8/2008 5:32 PM > > > Sad Safety Reminder - Pete Masterson - 06-09-2008 11:44 I believe the shocks where stopping the droop of the axles, so the stress wasn't on the air bags -- From what I could see, they were not over-extended. This may not be true on older coaches -- but it appeared to be the case on my '95. Indeed, on some modestly sloping camp sites, the leveling jacks will bring the wheels completely off the ground, so BB must have engineered the suspension to allow for that. CCW in Riverside does not have pits -- I'm told they're looking for a new location (for the complete facility) as they've outgrown the area they have, so they're not investing anything extra in the facilities they have beyond basic necesities. When the wanted to do a full examination of the underside (and wash the bottom of the engine, etc.) they used 6 "wheel jacks" -- huge hydraulic jacks that cradle each tire and raise up the coach (controlled by a computer that keeps them all moving together). It was an amazing thing to see. (I saw several busses raised up with the things while I was there.) However, for some aspects of the service, the work was done next to the "Blue Bird" section of the CCW facility. For example, the air dryer was removed (to be rebuilt) with the coach slightly raised to let the technicians roll under the coach on creepers. I think the technicians would be very happy to have a service pit -- and perhaps one will be made available in the future when CCW finds, builds, and moves to a new facility. When I was at Henderson's Line-Up in Grants Pass Oregon -- seeing how they worked on the coach from their pit made it very clear what an advantage it was. To tell the truth, I wish I had room for a pit for the maintenance items I handle (but that's far from likely to ever happen).
