Hey, question about dump trucks

Different strokes for different folks. I want to say my newest dump body is about 3, maybe 4 years old and it's in the standard configuration. I might have heard people say that the ram is easier to bleed inverted, also some other reasons people have told me they like that style but I honestly can't remember what they were. I've never had an issue with any of mine the normal style so I have never worried too much about it.

 

Some guys say it helps keep crud from hitting and building up on the cylinder seals when they are upside down. Makes since in really dirty environments.

 

True. Not to mention it’s gotta have a few more gallons of oil and a mile more of line to get it to the top don’t it?

 

The hydraulic inlet is still on bottom of inverted style. Many hoist cylinders have gone from pin mount to trunnion mount. Gives more flexibility in design and doesn't require such a stout hoist tower area. Many rams are changing finish from chrome to salt bath nitriding.

 

?

 

Here is picture of a trunnion mount set up that is becoming commonplace. This hoist is "traditional" in that largest stage is @ bottom.

 

All of our dump trucks use trunnion mounts except maybe one. I’d have to look again.

Our end dump trailer that I always use is pin mount.

Each cylinder stages are black finish which I thought was anodized instead of chrome.

If the cylinder was inverted, oil enters the small stage shaft, wouldn’t that make it weaker?
