Blackwall Hitch Double Blackwall Hitch - Attaching a Load to a Crane Hook
I am not sure, but I may be wrong, I would think that in this day and age the Blackwall Hitch is more of a novelty. In the days before health and safety the Blackwall Hitch was a way of attaching a load to the hook of a crane. It is such a simple hitch and it is only due to the crossing point on the crane hook that the load is locked tight.
I would also suggest the the Double Blackwall Hitch is not much more secure than the single version. Whilst the line around the hook is under tension, the hitch remains locked in place. Once the line is allowed to become slack, it is all to easy for Blackwall Hitch to come loose or free from the crane hook.

Johnny - though I wouldn't use this for lifting, I've used the Blackwall hitch for winching multi-ton logs up ramps onto a saw mill. It never slips as long as its under load. And, there's an easier way to "throw" the hitch over the bill of the hook by starting with an overhand loop facing away from the bill, dropping it over the bill and sliding it around the back.

Thanks for taking the time to leave a comment Robert. I have to say that I did test this a number of times and was really impressed with the speed and strength of this hitch. Thanks for letting me know that this particular hitch is still alive and kicking.

Great video thank you. You could also mention that slack can be taken out of the system by pulling on the running end.

@martinroberts2019 2 жыл бұрын

This would have been used by dockers moving huge amounts of cargo from a ship's hold. The big advantage is once the crane puts the load down the hitch falls free, no one needs to untie it. Pretty much a Sheet Bend, but round a hook rather than a bight in another line. 🙂

Great little knot. If you tie a figure 8 stopper on the end of the free end it will be much safer. Especially if the cordage is properly mated to the hook. Very useful for hanging gear temporarily. It works well tied in the fork of a branch too. 😀

Ashley has this to say about it: > The BLACKWALL HITCH is one of the most common applications of the SINGLE HITCH, but it is not to be trusted too far. At sea it is used in setting up rigging lanyards when they are too short to tie with a better hitch. The name BLACKW ALL HITCH was applied by Steel in 1794. So it seems that it was only really used when they had to.

This is such a fun knot because it is so simple and looks so insecure, but it holds even a heavier load as long as the load is maintained. It reminds me of the self tightening half hitch knot which has those same properties. You should check it out. I don't think you've done a video on it. I don't know if you want suggestions, but the Kalmyk loop is another cool but relatively obscure one I just learned. Thanks for keeping knotting interesting. Yours is one of my favorite channels

I am glad that you mention the Kalmyk loop, I was thinking about it only yesterday and could not think of the name!! I personally like the Imitation Slipped Bowline which looks rather similar: kzfaq.info/get/bejne/n5d7hr2XuK2pgJs.html

@claytonwaterman2301 5 жыл бұрын

@@KnottingKnots Hi Johnny, that is a nice little knot too. Easy, secure, and quick to tie. I do see similarities between it and the Kalmyk loop, but one advantage of the Kalmyk loop is that you don't need to have access to the end of your working end.it can be tied in the middle of the rope, yet it is not tied on a bite. I've rarely seen a knot that can do that. Just remember to be aware that the small loop that runs down the middle, parallel to the standing end goes around the standin end side of the loop that goes around whatever it is you are tying to, instead of the working end side. Then it won't slip. It's kind if like a slipped eskimo bowline in its structure. I will send you a link to a nice explanation video done in a KZfaq bushcraft video

@claytonwaterman2301 5 жыл бұрын

Sorry, cannot figure out how to send a link in a comment, but it as a man named Lonnie and his KZfaq channel called Far North Bushcraft and Survival. Just posted the video featuring three knots about 2 weeks ago.

@johnlinquist2998 5 жыл бұрын

I used to use this hitch all the time when lifting smaller loads (less than 1 ton say). It is secure as long as the load is maintained but as a security feature I used to leave the working end long and put a half hitch around the standing end below the hook to stop the hitch from working loose. You also need to bring your sling around quite high on the back of the hook. If the sling slips around to the bottom of the hook it will fail. The advantage of the Blackwall Hitch is that it is very quick to tie, won't jam and allows you to shorten the sling which is useful when you have limited head room.

@KnottingKnots 5 жыл бұрын

I am glad that this is still being used today!! Where do you work that requires this hitch?

@johnlinquist2998 5 жыл бұрын

I used to work as a rigger, mainly relocating machinery. Often headroom was very limited and on the smaller machines we would use flat nylon slings as short as possible. So far as safety goes the hitch won't slip if used properly and it is kept under tension. It is the rigger's responsibility to check the slings before each lift. Nobody should ever put any part of their body under a suspended load no matter how it is slung.

@jaaqess2525 2 жыл бұрын

Used to use this as a temporary when I needed to hold something like a tool or cable while I was building fiber optic plants, but I had a hook on either end of my hand line, so I would secure the end of the rope just to be safe. Never used it with any machinery though, and more often than not a larks head would do what I needed.

I first experienced this in use to lift a bucket of ‘bits’ - say 25 kg. I asked the riggers about it (I didn’t trust it!) and they said they use it ‘all the time’. I insisted they put a stopper in it (I showed them the Oyster stopper to their delight) - and to my surprise it didn’t slip at all! The key is to tension down the standing end as load is applied. Still: gotta keep things standard and safe - I won’t be using it! Why not just tie a decent loop knot? We’re not allowed to use anything but certified gear anyway so a sling would be more appropriate...

I think you have misunderstood the purpose of this hitch. The working end is attached to the load and you hold the standing part. Apply tension to the standing part and you lock the hitch, but can lower the load by easing off the tension on the standing part.

@nokieng6502 2 жыл бұрын

@Knucker…I think you’re right. But how do you control the descend of the load that has the working end by slacking the standing end, safely? There has to be some sort of ratcheting involved to catch the load at incremental steps so it doesn’t just drop when you’re ease tension on the standing end. Or you don’t burn your hands as you’re slipping the standing end, on say a pulley.
