Home made prawn puller.

Well, I just can't afford a new puller. So I made one out of an 24 volt electric wheel chair motor I bought on ebay. I designed it the same as a Ace puller but used a capstan instead of a large wheel. Check out the pictures http://www3.telus.net/public/a7a10165/a7a10165/PICT0597.JPG

The motor came with reduction box and a tensioner pully that I used. On 24 volt, the speed was too fast so I used a belt , 2 pullies and a capstan to reduce the speed. LOTS OF POWER... this baby lifts 4 traps with no problem at 100 feet per minute. I use my battery selector switch to isolate one of the battery that I connect to a spare battery for 24 volts. I use booster cable clamps for this (quick and easy). The cables are permanently monted to the spare battery. The set up takes about 1 minute including mounting the puller on the scotty mount.

Now, for the cost:
I bought 2 motors for $100.00 including shipping and taxes (EBay)because my buddy will also build one. I got most of the aluminum out of a metal waste bin at work. But i would think that it would not cost all that much if you bought it. The pullies, belt hardware, bearings for the capstan shaft (I used a 5/8 bolt), on/off switch (Heavy duty 50 amp), were bought at Canadian Tire for around $40.00.
The most expensive parts were the Capstan and the open end pully for the rope ($100.00 for both at Redden in Campbell River) maybe you can come up with a cheaper solution.. So the total is below $200.00 for a puller that will outdo any of the electric pullers that I used in the past.

You can also run these motors on 12 volts but the speed and the torque is reduced by at least half. although there is nothing that you can do about the loss of power so you may want to use a big wheel made of 2 aluminum frying pan bolted together (my original plan) and mount this directly on the motor shaft to increase the speed. I think that such a set up will lift 2 traps at 100 feet per minutes easily. Remember that the motor will last about 60% or 70% of its life on 12 volts.
good luck...
 
wow great job... I'm building one that is sorta the same as the Ace pullers. I got a gear reduction motor from Ocean Outdoor Gear. Hope it works...Ha Ha. Good fishing. Al
 
That looks very good! You should consider making a few extra and selling them!
 
Thanks for the comments...:D
I only posted to seed an idea in someone else head. I just couldn't afford to spend upward of $600.00 for one of these ace hauler. However, a couple of hun is not too bad. Think about it next time you are hand pulling the 3rd haul of a couple of sets. Ouch!
But yeah, I like it a lot. Now if only the traps could get filled.:)
 
very nice How many feet per minute does it pull is it faster then the ace puller
 
Falcor
Over 100 feet per minutes with 4 traps on 24 volts. The speed can be changed by using different size pullies. Faster speed = less torque. I think 100 feet/min is plenty. it would go faster with less traps on a line. I tried an ace puller about 3 weeks ago and yes, this set up pulls faster and heavier than an Ace puller. But like i said, the speed can be altered. On 12 volts, the speed and the torque are cut by over half. So the capstan should be mounted on the main shaft of the gearbox or the pully ratio should be altered.
 
Your idea: "you may want to use a big wheel made of 2 aluminum frying pan bolted together" is perfect.
I've been trying to figure out an inexpensive large pulley for a prawn puller that I am building and your suggestion really rung a bell. I went to WalMart and found two smaller size pizza pans that will make a great pulley when bolted back to back. Now I just need to make a hub. Thanks for the idea!

If I had gone with the frying pans idea, I would have used a sheave from Canadian tire as a hub and bolt it to the pans. Their sheaves fit from 1/2 " to 3/4" shaft and are keyed.
 
Awesome DIY plans! I've looking around for ideas! I was thinking of using a starter of an old car to turn the hauler. Spose that would work?
 
Makes sense, I wonder how many hp a wheelchair motor is...I know you can pick up 2hp treadmill motors for like 30-40 bux....
 
I made one out of an atv winch motor in metal work a few years ago. It was a bad layout and not thought through as the motor has alot of torque but slow rpm. If you put a large drum on it then it would be a nice setup. I think blueorca might have done this as well.
 
fyi - an ace line hauler with an 11 inch wheel is about 45 rpm under no/light load. This will give you a benchmark to evaluate various motors and the requirement to gear them down...

Just finishing up an adaptation of a Superwinch T1500 to an Ace wheel/frame will report back in the next few days on the success of the gearing ratio on that winch. Fingers crossed.
 
Anyone have the phone number or email address for Island plastics in Campbell river? they will make up a pillow block and pulley out of plastic for these pullers

Do you have measurements for your trap puller frame.
I am making one and using a motor from an electric scooter with a gear box.

Thanks for the help.

bounty.
 
When I'm not fishing I'm a mechanical designer (Comox).
I could draw one up, but the design depends on your components.
Gear ratio and sheave selection will come into play.
Let's engineer this and make a few.
