Dont cry, just do it
I was looking at buying a Portable Winch Co. PCW-5000 Portable Capstan Winch and I wanted to see who uses them, and how well. Can you idle up and down to control the speed of the capstan?
Mr. Ryan....
Sometimes it's not the speed of a particular operation that causes it to be superior......it's the efficiency.
How many hemlock logs can you carry uphill in a day without being tired?
I have the Simpson winch, attached to a Shindaiwa 488 chainsaw. Less the bar & chain, of course.
We don't use it often, and you need to know where it is effective, and where it is not. I consider it a very useful tool, and I have no intention of selling it. It enables me to do some jobs at reduced labor expense that I could not do any other way except small logs and loads of labor.
Where it excels: putting more horsepower on a rope than any 4 men can do. If you have a situation where no machinery is available, and you have a big need for relatively rapid pulling on a rope, this is the tool for you. It does not pull harder than a simple little Maasdam rope winch, but it pulls a whole lot faster. With that kind of power on the end of the rope, you can afford to use pulley systems of 2 or 3:1 and really move some sizable logs.
Sure, men can cut up logs into 50lb chunks and crawl up a real steep grade, but they are worn out after one trip. My winch will pull 500lbs all day long and not get tired. Rigging with a pulley to an overhead lift point helps keep the logs from digging in, too.
The capstan is effective while controlling a winch load, but not as good as a port-a-wrap. One of my stories here: http://www.arboristsite.com/commercial-tree-care-climbing/170092.htm
Where it performs poorly:
It is a bit cumbersome and annoying to set up for a simple pull. If all you are doing is pulling
over a tree in some back yard, a few pulleys and a long rope are lighter and faster.
It is NOT as reliable as a hand winch or other proven methods. If you overestimate it's strength, you could put yourself in a heck of a hard spot on a leaning tree. I tend to not rely on it for that purpose very often.
You CANNOT count on lowering a load very far from the capstan winch. Feed it too far and it binds up on itself. It simply isn't designed to provide lowering capacity.
My Simpson winch relies on a chainsaw motor, which requires one man to operate the throttle, while two free hands are needed for pulling in the winch line. Basically, it's a two man operation, or you need a throttle lock of some sort. The model you are looking at probably doesn't have that problem.
It is a bit touchy about twists in a rope. While the capstan style of winches pull more aggressively with 3-strand rope, that type of rope tends to accumulate twists. At the end of a long pull, all the twists tend to get concentrated on the end, and then you have kinks galore when you take the load off the winch. Not a big problem with double braid rope, but that doesn't bind as well on the capstan as 3-strand. Don't try amsteel blue, that stuff is too slick and melts too easy.
Speaking of melting rope; idiots that are not real well trained can melt a rope down by overloading or not releasing a load while the capstan keeps turning. This is not your everyday tree equipment, and some folks don't seem to grasp all the important concepts to using it effectively.
It will never outperform a tractor or truck pulling logs. Those who think that they are too slow were not using it where it is well suited for the job. Use the right machine for each job.
