Default Getting rid of the green

I was given a battery operated forklift and a Honda 18 horse a while back, and I have begun to work on it. My plan is to get rid of all the non functioning eco-shit and turn this into a greenhouse gas spouting useful tool.
Here it is before I ripped out the electrics. pic 1
The machine is basically hydraulic. It has an electric motor driving a hydraulic pump to power the mast, and an electric motor for the drive axle. Pic 2
My plan is to strap a pump on the Honda, and throw it into the empty battery compartment, use the stock hydraulic tank and filter system, and add a circuit to hydraulically power the drive wheels.

I pressed the driveshaft out of the electric motor, and used the front motor bearing and the shaft to make an adapter from the pinion gear to the hydraulic motor.
I used 2 plates of steel, one plate registers on the electric motor housing registry, and bolts to the front motor bell casting. I machined a recess 1/2 way in each plate and used the bearing as a register to align one plate to the other, and this also keeps the shaft from any back and forth end float. The hydraulic motor mounting adapter is used to clamp the whole samwitch together.
Picture 2 shows it ready to mount the motor.
Picture 3 shows the assembly.

Looks like a very comfortable morphing of technologies.

All of this done since breakfast?

Just a thought.

That big ugly battery serves two purposes. Other than power its also ballast. Do you have plans on adding weight?

Yes. I have a bunch of 3 inch thick plate cut outs from tank manufacturing that I plan to add.
I expect that I will have a lower capacity, but this will be an indoor and around the shop tool only. It has a cast iron weight on the back, but without the battery I expect a max lift of only a ton. I have the front end loader for any serious lifting, but alot of the time I need a smaller machine.

LW, I have been snatching moments to work on this since May, and it has been permanently on the back burner. Now the craziness has slowed down, i am getting at it. I have mad some progress and more today

You'd think that big ass battery would be worth something in scrap. I took some old CAT battery's (Think they were C's) off for the company a while back. And I think they were 100 bucks a piece scrap.

And I'm sure that big o'l motor will find a use some day Just don't hurt your back working on that thing. Last time I worked on one, it pissed me off something awful No room.

But yeah, that looks like the perfect little shop forklift. The pump assembly you made looks factory.

3" plate from tanks? You rebuilding Panzers and Shermans up there?

Actually I passed a bunch of tank parts on the Busy Lizzie the other day. The tank cylinder was all of 3" thick. The cylinder was 10' long and roughly 6' in diameter. The two ends were laid on lumber either side of the main piece. Looked like it was on it's way to a shop to be glued together. With material that thick, I would expect high deposition sub-arc. Not every fab shop in town would have one nor the roller set-ups to roll the tank for the end seams.

The forklift looks like a great addition to the shop tools. Looks good so far, especially the motor mount. Sadly, them little hard tires mean it'd be close to useless off the concrete though.

Cam, those cutouts came from down your way. There is a tank mfg out in Carstairs or Airdrie they came from.
This Forklift will be only for inside the new shop. I have the loader for out in the mud.

Rogue, the guy that gave it to me is a scrapper. He took the battery right off.
He bought a dozen of these machines at auction for $45 each. He gets $200 for the battery, $35 for the copper wire and motors, he sells the forks for $200, and sometimes sells the mast for $300, and chops up the rest for scrap steel.
He lost alot giving me that thing

Prob'ly these guys.

I had the opportunity to tour the facility 2 owners and 25 years ago (gawd, I feel old allofasudden) It was the first and largest subarc installation I've ever seen. They were welding the seams on semi trailer propane tanks...
