Think about it ...

4000 lbs / 7 = 571 lbs

I can't pull 571 lbs!

Bought something similar, years ago ... junk. But hey, sometimes things do get better

I used one to lift a 170 lb deer from my truck

Good luck with that 1/4 inch polyprop. line. I found it very useless.

wouldn't that mean you would never exceed the WLL, Reducing the risk of it breaking? But I agree, it looks like it is just waiting for you to use it so it can break!

Call me crazy, but that's not really a 7:1 MA at all, right? More like 2:1.

 

[chewbacca]

If you ever seen one of those things in person, you'll notice they are quite flimsy. Not at all something useful for tree work. Hoisting a deer? Maybe (a small one).

haha i think a cmi double sheave micro pully advantage kit would do the same thing in a smaller size. when do you ever need a 6-1 advantage??

Hey crazy, how do you figure 2:1

Count the parts of rope at the traveling block. In the image, it is set up as a 7 to 1 MA.


Looks like it's very cheaply made. I, personally, wouldn't invest in it. Accident waiting to happen in tree care.

If the sheaves are independent then it's a 7:1. It could be useful for tightlining but 5:1 fiddle block is a lot neater and easier to keep sorted out... never mind how much beefier it is.

I can see wanting 7:1 for getting trees off structures or pulling out a hangup. I've put a 3:1 on the downhaul of a 5:1 before... great aerobic exercise, definitely pushed the WLL.

I think the WLL on that thing is based on the system capacity, with a fiddle block each component is rated for the WLL.

made in china.......

 

[treemaninmo]

i dont like having ANY unrated equipment around in case u have a new groundie , and you are out back and he sets a line and tries pulling himself up a tree out front thinkin hes a climber and winds up hurt

just one scenario i can think of
