Technical New one for me... Broken lift

"Everything old, is new again"​

 

We're still around , albeit past our prime ,but we're still here !

 

Alright, here's a bit more info with corrections.... This is a Challenger brand 2-post lift, the problem is one side won't go down. This is in the car owners' shop, not a commercial shop. He's had three different techs out to look at it, all claiming they've never seen this problem before. The problem appears to be hydraulic. The last tech has decided that the valve that controls fluid in/out of the cylinder has malfunctioned or has a blocked orifice in the cylinder, not allowing the fluid to exit, they have cribbed the car for support and removed the cylinder. They're currently waiting for the replacement cylinder, due in at any time...

He has a possible back-up plan, a guy with a flatbed car hauler (which can fit under the lift/car) will try cribbing up to the car off the truck bed. That way only 2' of cribbing will be needed instead of 6'.

I'll try to follow up as I learn more....

 

I would say If all the way up , with like a F450 or bigger model from deck to wheels of Car on lift about 18 to 24 inch difference, with thought it can be done

 

“off shore” lift?

 

Challenger is part of Snap-On. They sell USA and Imports.

 

So I guess lift cylinders use a restricted port to lower the lift? Maybe for safety in case the valve fails?
I’m used to hydraulics with farm equipment, no safety required. Well, maybe on newer stuff than I’ve ever had.

 

Correct, that way if they come down it’s slowly.

 

That makes sense.
Thanks.

 

I have an Atlas BP9000 (two post, asymetric arms, baseplate). Mine (I thought most, if not all) has a knob to adjust lowering speed. I have to remember to use it. When I open it up so a 1500# car will come down (cranked in, this can be a LONG process), a pick-up comes down scary fast if I forget to tighten it back up. One knob, both cylinders adjust. If you want an empty lift to come down in your lifetime, you have to open it way up. This will get your attention when you forget. Mike

 

So , mostly offshore stuff ?!
