Thanks for taking the time to post that. I've been operating a Grove 35 ton crane for about 8 months myself. I already understood most of this but it never hurts to have it reinforced by someone with a lot of experience. We put the jib on for our first time a couple of weeks ago an managed to get the cable snarled up even though we had a small loader pulling on it to try to keep it tight. It's something I would like to avoid doing again. I'll be doing it differently next time around. We're using our crane for doing tree work only.

@@ToTheTopCrane Yes I could see that. There's a lot of unknowns when doing tree work. Are you familiar with wet wood weight calculators? They help a lot by at least giving you approximate weights. They don't however take into account the foliage which can ad up a lot. The crotches are also more dense. We aim to work at 60% of the chart max to allow for slight miscalculations. The weight is also variable due to how much water is in the tree at that point in time. We've been doing crane work for years but we got to the point of buying our own in 2018. I really appreciate the offer of help. I may take you up on it at some point. Thanks for taking us along with your crane adventures.

Great explanation, thanks. In theory you can pick up a 100 ton load with 25 ton rope, if you have enough wraps around the blocks.

Ya done good! Even your artwork was discernible. I did a 28 ton Pioneer for a time, and the cable would stack two or three lays on the left side of the drum before it would drop down in place. That meant that the load would drop every time with it. They finally resolved the problem but sure was unnerving when a load would drop 'n bounce like that. The Pioneer was the only unit that has a 2° & 10° offsetable jib and stinger, wireless LMI, 94' main, with a tip height of height just short of a hundred and fifty feet. It was quite a machine. They got bought up and shut down during a monopoly Shuffle. Wishing y'all a safe, prosperous and blessed New Year!

Great explanation! I was setting up for a truss job with some pretty long picks a couple years ago, I had ran out enough boom for the job and as is my habit I ran the line up into the a2b for a function test and all was good so I started swing back to the pile for my first pick booming down slewing and winching down while watching out the side window judging the radius for my first pick, I looked back at my boom tip and the ball had not been lowering. It turned out that the a2b chain had got fouled in the line clamp on my tail. Long story short it cost me a $4,000 line. The only good thing was the line was scheduled for replacement anyway.

Lacing is when the rope comes into one side of the block, reeving the rope comes into the centre of the block. Reeving keeps the block even.

Nicely explained

I think you just answered my question - what is the little collar that hangs from the chain at the end of the boom tip? Sounds like that's the anti two block device. Prevents the lower block from crashing into the upper block.

Revers mechanical advantage, boom angle, hook height limit and why they are so important.

good video. Im getting ready to buy all new rope for my Insley. Not quite sure how the shipper shaft gets reeved and the manual doesn't go over it well. cable was already broken so I have nothing to go by. Main boom shows it better and is pretty simple.

You can improve gravity descent in a friction rig by disengaging the engine clutch, and engaging the "lift" brakes... This will force your load to turn all the draw works too.,.

Does it work to run 2 parts of line on a 3 sheave block? It seems like it wouldn't be very stable but I've never tried it.

Question. On lifts where multiple parts are used, each part will "move" at different speeds with the first part moving the fastest. How do you keep the block/hook level if each part is moving differently?

@ToTheTopCrane

Each part of line is reeved around it's own sheave. The sheaves can turn at different speeds. They share a pin, but are independent of eachother. Hope that makes sense.

i just bought a 1979 Drott without a blockt then found a beautiful 30 ton mckissick at an auction for thirty bux!..im going to reeve it 3 parts..using 2 sheaves top and one at the block then deadman at the block..right? its got 2 sheaves on the block but i will only use one,,,plus the deadman...i puuled off all the 5/8 cable because it birdnested on the last guy who was silly...how do it get it to go back on the winch drum smooth? i thought maybe i will hook the rope to a pickup not running and roll it up on the drum,using the pickup as a load...whatcha think?

My question is a bit off the subject, but I see plenty of cranes tipping over due to various reasons...I can see how trying to recover by 'boom down' would fail, by instantly increasing the lift radius….BUT what about releasing the winch to sort of 'free-wheel'...? Is this even possible, and would/could it help save the crane...??

@ToTheTopCrane

5 жыл бұрын

Doug Ankrum, the newer cranes don't have free fall. So, the only recovery would be cable down as fast as possible, and possibly boom up (but that may upset it even worse). But, trying something would be better than trying nothing. Whether it would work or not, depends on lots of variables. Many thanks for watching! 🙂👍

@tiredoldmechanic1791

5 жыл бұрын

The older cable cranes were friction operated so they had a brake on the drum that could be quickly released to recover in a tipping situation. Hydraulic winches can't do that. Even the ones that can be free spooled can't be released under load. That's why it's so important to keep everything within the safe operating limits of the crane.

when you determine how many parts of line you'll need for a bigger lift do you base it off of line pull or winch pull. ie depending what layer on the drum you are would limit how much you could lift?im just thinking about a heavy object that just has enough parts of line to make the lift and you are near the top of the boom so you would be on your largest layer on the drum. i haven't been in that situation yet but i have made lifts near the max line pull and the winch would be jumpy.

@ToTheTopCrane

We base it off of line pull. The winch is actually rated for more than line pull. But, is de-rated down to line pull by the manufacturer. If your winch is jumpy, you may have a mechanical issue or too much rope on the winch.
