need to determine torque required
(OP)
Hey all. You helped me alot on a thermo problem and never formally thanked you, so please consider this it. In the meantime, I need to figure out how to determine the torque required to move a load horizontally with either a hydraulic motor/gearbox or an electric motor/gearbox. I would prefer hydraulics because I have speed control at my fingertips with a needle valve.
I plan on using 1 drive source turning a shaft at 20 rpm. this shaft will have 3 driven 12" spockets - 1 at about 6" from the gearbox, and the next 2 at 4 feet and 8 ft. These are the drive sprockets. Each drive sprocket will have a driven sprocket approximately 10 feet away. The top portions (from the top of each sprocket) of each chain will be taut, and there will be a spring loaded ider sprocket holding the chain down taut on the bottom (or return) portion of the chain. The idea is to actuate the chains in motion and drop a pallet weighing up to 7,000 pounds over an edge into a scrap bucket.
The 12" sprocket and speed was determined by a very basic need of moving the load at approximately 1 foot per second. The chain is specially designed and used in another area of our facility to move much larger loads around (up to 50,000 pounds). They system works pretty well and I am trying to adapt it on a much smaller scale for a different application. Only problem is that each link of the existing chain is about 10 inches long - way way more than we need.

1) dragging a pallet untill it falls into the scrap bucket ... "drop a pallet weighing up to 7,000 pounds over an edge into a scrap bucket."
or 2) pivoting the scrap bucket untill the 7000 lbs of scrap falls out.
i'm having a little trouble seeing how three chain drives will drag a load; and push it back again ??
