Rope come-a-long question

[mbarker]

A while back on a job site I saw a come-a-long that instead of using cable it used 1/2 inch rope. I believe that there was a slot in the hub and you just fed the rope through the hub and pulled it tight then started cranking. Has anyone heard of this product and if so any info you can pass on would be helpfull. Thanks Mark

I have one of those. I won it at a competition one time. It works prertty good. I've used safety blue, true blue, and blue stripe in there. The only pain the ass is pulling the rope back through when your done pulling. The rope doesn't wind up on the spool it just feeds out the other end like a grcs does. It can be pretty handy when you need. When you need it you need it.

That comealong works best using a three strand rope. It does work with sixteen strand arbo rope but it has been known to slip. Mine is rigged with about thirty feet of three strand that stays on all of the time.

thanks

Thanks for the prompt reply. That unit was exactly what I was looking for. I ordered it and some rope. Thanks again. Mark

I found that three strand does work nicely on the rope come along. The tighter braid makes feeding it in easier too. I just dont have laying around anymore.

I usually just feed what ever tag line is in the tree at the time unless it it a bull rope.

I've had mine slip a little with some 16 strand 1/2 "
When pulling on some heavy trees.
Not sure what it's rated at ... But id say less than 1000 lbs

 

[treeman82]

I think they are only rated for 500 lbs. Can't say for certain, but I think I remember reading that on my old one.

As everybody has said they are great, i have only used them for cabling, but other uses should be fine, always used 3 strand rope.

Two men using a bowline on the bight as an advantage will exert over 500lbs. Seems to me that the safe load limit may be exceeded using half inch line, the safe working load is 5-1 so a half inch lines rating is 1200lbs if the rope is rated 6000lbs b.s., knots reduce this figure to well under 1200lbs.. Asking for problems pulling a big leaner over backwards, be carefull.

puller ratings

I have one and with the 16 strand Blue Streak the rope starts to slip at 700-900 lbs. With three strand Safety Blue the rope starts to slip 1200-1500 lbs. I like the rope puller but you need to know it's limitations. Yes, it can pull a lot more than two groundmen can but DON"T try to overload it and get away with it. The rope will slide back. You want to pull more get a mechanical advantage with block or block and tackle, wedges. The advantage is the puller works with rope. We got rope in our kit.

I caught a glove in mine and messed up the spring on the ratchet pawl? I called the company and they were very helpful on the phone. A rebuild /repair kit was only five bucks and they shipped immediatly.
Last year I bought the second one. Almost as good as another set of hands.

I need a spring for mine .

Do you remember the contact info where you got it from ?

Two grown men pulling on a straight line should be able to exert at least 500 pounds of pull. Unless they built like women. They should be able to pull a bit more than their own body weight. Aren't most men over 200 #s?

said it already, notice with a bowline on the bight for added pull, do ya do that, or is it too simple for ya?

 

[Tom Dunlap]

Some people who work in rope rescue did pull tests to determine how many people were needed to lift a load. The test was very involved and accounted for a lot of variables. When all of the data was combined they found that a person can exert a pull equal to about 80% of their body weight on a rope.

Now, run that 80% load up at an angle like we would see in a pull over and the load on the anchor point is more than 80% but still wouldn't be amplified like we might think.

I wish that I could cite chapter and verse on the test but the bookmark got lost when a hard drive was reformatted.

Woodchux, the no. is 818 845 8769 Have the puller handy, seems like they need info from the handle.

Thanks John

Without that spring it can be a real finger pincher for some of the guys .

Exactly!!
I tried hanging a rather large deer from the rafter in my barn using my four wheel ATV and although I have hoisted deer up there before with it, this big old buck was too heavy and my tires started spinning on the barn floor. Me and my hunting partner tried hoisting it up by pulling and couldn't do as well as the four wheeler. I then remembered that I use a bowline on a bite almost everyday at work, and was able to pull the deer up all by my self. We use a Kawasaki Mule at work for pulling climbers up into the top of the trees and for hauling tools and brush out of back yards, very useful tool. We have found that 2 men with a bowline on a bite can put more pulling force on a tree than the Mule can. Now days though we also have a wench on our chipper that we use.

Dang, that's cool! How much can SHE pull? Is she big? Where did you find her? I wouldn't even know where to start looking for a chipper wench. :monkey:
