Baker Fan

[Anonymous-0]

Could a truck rear axle be used to build a baker fan. Could the prop/drive shaft be linked up to the tractor PTO. Would one wheel need to be braked? Could the original braking system be used to apply additional load. What diameter of blades would be needed to handle up to 200hp? Any thoughts appreciated.
Thanks

Your idea sounds interesting.
Just using brakes would probably get too hot, and wear out the brakes.
Do you have access to an old baker fan? I'm no engineer. I would start with 2 fans, one on each wheel end. Size the fans the same as the old one. If one old fan would load a 60H.P., a double one should load the bigger tractors.
Then the liability issues, be sure everything is anchored down well, shielded well, and quality materials that it won't blow apart.

yes you can use a truck rear end to drive the fan . connect the fan to one end and use the off side brake as a clutch. be sure not to use a postive traction rear end. failing(sp) used the rear end from a F 8 ford truck on their drilling rigs for years. use the brake on the drive side to stop your fan, release the off side brake first. you can use this same set up to make a wench.

Maybe you could make a winch with one but I highly doubt that you could make wench out of a truck rear end.

I know, I am just being picky today.

Shaft power into the axle end, fan on the pinion. This spins the fan faster, and makes it smaller. use the other brake to act as a clutch. Be sure to drive it so the force is the same as it was designed for, they do not like reverse. JimN

Public liability if it flies apart. 200HP is a lot of torque at 1000rpm.
100+KW and larger 3 phase alternators sell dirt cheap as the few people in that power category
want a used unit.
A six or eight pole generator could be direct driven from a 1000rpm pto and do well enough.

A load bank of old forced air electric furnaces require no cooling water.
These electric outfits have no oil or water to leak and make a mess.

It takes a lot more power to turn one than you'd think just looking at them. The photo shows a couple that are owned by ???? Dang! Can't remember who sent this to me but he's on here a lot and I believe he's from SE Wyoming. The link is from a post on this site by Joe Evans.
I am in the process of collecting the pieces to make one which is going to be similar to these but I plan to set it up to use the PTO as well.
