Designing a bin tipper, sizing hydraulics.

Also, Seeing that it has dual cylinders, would I need to worry about balancing the two of them so they extend at the same rate?

The dumper frame would keep the cylinders in phase, and as for the pivots, either would work fine. The bearings will require a lot less maintenance , were the pin bushing set up will require a lot more greasing and be a bit messy.

Good advice.

. Plus depending on where you are a food safe grade grease would prob need to be used.

Oenophile's shun greasy wines. Probably why wines are rarely paired with french fries.

Food safe grease and hydraulic fluid would probably be a good choice...

Yeah good point on the messy / mantinence factor on the pin bushings. Pillow block for the win. I do feel like I might stick with the single cylinder in the middle. Feels like less overall complication of the design for me. That is unless anyone has a good reason to go double. I see both ways in the commercial versions. Those reference pics also feel like they are a good reference for burly factor / metal sizing / probably a bit more burly than I need to go.

As a point of reference the dumper I sent photos of would be typically used for a bin gross weight of 1000 pounds.

Depending on moisture content of your grapes (or how deep you load your bin) I suppose you could use a central mounted single cylinder. Personally I would use two for the greater lift capacity for possible different applications and (or) resale.

The ones I'm talking about are not for a forklift. Pretty hard to get a forklift into a 36in door in construction sites. Something like this and maybe raise it up higher

Those can only dump on the ground or over a ledge.

yeah i definitely need the lift height so the auto tippers like that wont work form me. I guess for the single i need to calculate how big a cylinder i need. Typically a bin will weight 800-1100 pounds. so that lift you referenced is right in my range.
