Hand-held Drill Machine for rigging 3

[m2e]

I'm looking for a heavy duty hand-held drill machine. What it does is to drive a winch on site to lift up ~1700 lbs of load. It needs to have a speed of ~10 fpm rise.

I've found this product and have tested it. It was able to lift up the load, but it only archive about 1/3 the speed.

Does anybody know any similar product that will run off 110V but provide a higher horsepower?

Thanks.

A 1T electric hoist will probably be cheaper, and will certainly be safer.

I agree with Mike. If you are looking for something that runs off of 110 power, you will be drawing a huge current.

1/2 hp? Yeah HUGE.

Oops. I read 17,000 lbs and not 1,700 lbs.

Good catch Greg. I guess 3 Amps isn't a huge draw for most circuits.

I was thinking in particular of an account I read, which I cannot find right now, of an incident involving a drill- powered winch used for hoisting.

Short version: The improvised hoist, not properly designed for hoisting, e.g, lacking an automatic load brake, failed and dropped the load. Personal injuries resulted, and large sums of money changed hands.

Thanks for all the inputs. Basically a hoist is not possible in this situation because the driving unit has to be on the ground and the load is suspended in the air with a pulley on a structure. Therefore, the motor has to be on the ground and not mounted on the structure permanently. The operator has to bring the motor to the site and drive the winch. The winch has a brake in it so falling isn't a problem.

I can't picture your set-up. Is the winch that you need to drive a permenant fixture, and you take a "motor" of some sort to it? Where is the actual winch mounted? Can you draw us a picture of this set-up? Sounds rather dodgey (and dangerous) to me!

Having a wee bit of experience in this field, I'd say a drill motor is great for drilling holes, mixing paint or whatever, but not as a hoist motor. I would go with Mike's idea and pick up a nice little electric hoist. Man, even a $49 cheapie from Harbor Freight will be safer than a 'drill'!!!

Thanks for your comment, I agree that a hoist would do the job, but if so, the hoist need to be on the ground level and be portable.

Here's the concept of the problem:

The load is carried by a simple structure. There's nothing but some simple pulleys and a brake winch on the structure. We're to go to the site, lower the load, service it, and crank it back up. Hand crank is available but we're trying to find a "drill" of some sort to crank it up.

Maybe a "drill" is mis-leading. The link I've initially posted was actually a "electrical bore machine".

Is there any kind of hoist or "turning machine" you know of that can provide the kind of power we need? (1700lb and 10fpm)

Thanks.

From a safety aspect, I'd want to stay well clear of your winch assembly!
Why not get a simple electric vehicle winch, 12 or 24 volt, and use that? This would make you even more portable as you could take HD batteries to power it.
This site in UK,

http://www.electricwinches.co.uk/index.htm

has several examples, their smallest one capable of lifting 3000lbs!
I'm sure you can find the same wherever you are, and they are not expensive.
THINK SAFETY! KEEP CLEAR!

 

[m2e]

Thanks Cheddarcaveman for your input. That seems to be ideal. 3000lbs! But how do you make it portable? We need to leave the winch with the structure, and take the motor away. With the vehicle winch, the whole thing (drum, cable and motor) is in one unit.

 

[Cheddarcaveman]

OK. Why do you need to leave the winch with the structure and take the motor away? Why not leave the whole thing there?
Alternatively, if you do have to remove the motor/winch (for another job?) then you could run the cable above the winch through a "clamping device". You can than clamp the cable once you have raised the load to its resting position, remove the cable from the winch all together, which is quite an easy thing to do with a vehicle winch, and take the whole thing away to the next job??? Just a possibility!
Just for the record, what on earth is this huge weight doing suspended up in the air?

 

[Cheddarcaveman]

Just had another thought. How high is this lift? Could you use a hand winch rather than a powered one?
Look at the hand recovery winches on this site - they are easy to use, cheaper and are "self clamping".

Amazing what you can find out in a cave!!!

Could this be adapted for your application.

The Rigid Company used to make a portable drive unit on two wheels, we used it to power our sheet metal roll. I don't know if they still have them, but hand held portable threading machines are available, and could be adapted for your winch.

The electric utility companies used to use a winch that clamped, like a pipe clamp, on any size pole for hoisting transformers and things to the top of their poles prior to boom trucks and cherry pickers. I'll try to find my old literature.

 

[m2e]

Thanks Metalfixer and unclesyd! Those would be the things I'm looking for exactly, thanks!!

 

[unclesyd]

Here is something like I was referring to. I haven't been able to find my literature as of yet. Trying to catch a utility truck with some older guys as the power company maintenance yard is locked down.
