Lift Mechanism

[bryankloos]

Hello All,

I have a new to us 2018 HW296. Love it!
That said, the lift mechanism makes a loud bang once or twice as she raises.
What could be the cause, and where can I find the specs/schematics etc for the mechanism?

All help is appreciated.

Thanks,

Bryan

My HW27KS does this when raising & lowering. There's a thread on here somewhere discussing it as it's quite common. Mine is the telescoping lifting posts, I think there are 2 or 3 sections to it, it's like a section will start to raise but there's nothing to hold it in place yet, so slides back down. I have actually watched one of mine do it, scares the hell out of me each time it 'bangs'
Someone suggested putting some dry lube on the inside of the posts, I haven't done it yet but plan to.

Here's the thread regarding the discussion of the loud bang noise.

Flagstaff 228D here, similar noises, mine stem from those posts mentioned (usually on the way down with the roof) and the steal cable that is under pressure when raising it. As the cable winds it's"clunking" into various grooves as it's winding. I had the cover off a few years ago to try to fix an issue and saw it happening.

Hopefully that's all it is for yours too.

In '95 when we bought our first new popup with the open wench it would do the same thing as the cable wound up on the spool, the cable would jump into another position causing a bang. It would usually happen when the cable was near the outer sides of the spool. There's not much you can do other than using cable lube on a regular basis.
