how do you know how much is the load

I’m assuming that the hole by the tip is so you can mouse the hook if desired?

Very good video to learn about the load angle factor of the slings above the hooks.

Would be beneficial if you were to include examples and show point by point inspections. I travelled with a large contractor. Thankfully, never personally saw or had a failure. I know of three rigging/ lift incidents in almost 50 years that occurred on other jobsites. One was, from what I recall, a crane operator error of some type which resulted in a fatality at a hospital construction site. Only one was due to actual rigging component failure. Falls and trips caused many injuries and some deaths

so cool!!

Just for humor!!! I am the designer of FORGE FRANCE safety lifting hooks I designed the CL.7 24/26 caliber chain in 1999 which everyone subsequently copied Proof ! Follow the link for info!!!! ua-cam.com/video/OJjhkYwRsQk/v-deo.html&ab_channel=jackytanski

Ok nice

Muito bonito

like it!!

Thank you

How

China sells rigging manufacturers.

What if I put 2 side loads on it.. in opposite directions

Girls big friends are sometimes snatch blocks

No your awesome

Thank you for the info

Crosby, thank you for posting and I would love to use one of these in a video... I will check your webpage. Thank you.

Thank you

12 years ago that video already had like another 12 yearsof being made lol

great video I learned a few things

Hi, do you need to do a similar process for pairing with the SW-BS? Do I need to unpair the handheld as well? I have the SW-BS connected to a GL240 data logger with a 250ohm shunt resistor to convert the amp signal into volts, but it's not giving us anything when a load is applied. We have checked all the wiring and all the input and output power levels and it all seems ok. The input voltage is 12V DC, the signal is showing 10V, and with the shunt the voltage across the signal wires is 4V, but no variance (and we expected close to 1V (given the signal is 4-20mA). All I can think of is that the SW-BS isn't connected to the Radio link plus load cell (12te). Please help!

Im trying to tighten my round pin anchor schakel but it just keeps spinning 😂

very bad quality. no primer

Do you guys recommend placing a shackle onto the choking eye to increase bend radius and less cable on cable friction?

is this a self-locking clamp?

Hello sir how can I join on-line lifting and rigging course

Jason, I enjoy the Crosby short videos very much, but I would like to share some thoughts on this particular subject. If I adhere to the Crosby Hoist hook instructions, most importantly in-line loading straight through the hook, centered in the bowl, it does not matter if the hooks are inward facing or outward facing. Your demonstration in the video will apply to a hook and shackle in any attitude. When load is applied, regardless of positioning, the shackle, or swivel, by virtue of the radius of the hook design, will seek out the bottom of the bowl. Therefore centered in the bowl. Without getting into the dozens of scenarios where hooking out would create a hazard for the rigger, we teach "best use", of the product (adhering to the manufacturers instructions). In other words, after creating the rigging plan, including the loads movement through the transition, we will develop how the rigging gear will be oriented, including hooks. I really think when we say, "hooks must be pointed outward on multiple bridles", we are probably speaking about chain grab hooks. In Crosby's Edition 7 "Fundamentals "red book", Section IV-A Page 5, there is an image (POH295A) showing chain slings and their incorrect use. I am 1000% in agreement with the chain image, as the loading is pulling toward the open part of the hook. In this case, an outward facing hook directive would apply. However, the other two correct images shown would perform equally to the task if hooks were pointed inward. At the end of the day, properly trained personnel who know to look for these things as the load is applied, is the last line of defense for safety. Regards

Hello brother, how The sheaves can be set on a single shaft, four winding drums. Can you please send me a sketch

I had no idea a loads weight doubled. One being gravity and the other being load weight

I inspect a ton of chain and Gunnebo GBK hooks are almost always used for choking and you can tell because there will be excessive sideplay in the hooks but also the bottom 1/3 of the chain legs will have the coating worn off. Hooks are often bent or broken off when used in this fashion and the proper choker hooks should be used but customers will continually buy new rigging and repeat.

People have different opinions. I have seen that people asked the hardness for refuse cranes (class F) in the range of 380-500BHN (42-52 Rockwell"C") in the past. It would be interesting to see what the reasonable number is.

What does the engineer say about side loading his lug. I guarantee he didn’t design for this application

But the question is really good and not answered specifically through some example of exception. I tried and cannot find any exception with different cases. Please clarify

How to find centre of gravity for unequal load if only total load is given and not separate load..

FOR LANCE STORZ, WHO SAID NO MORE TODAY MAYBE TOMORROW, SOMETIME CHRISTIAN MEN ARE HATED, NO MORE, JUST NOT TODAY, OK.

Excellent demo. Concise and to the point. No fluff. Thanks! 👍😊

This is great. I will save it for all of the off road videos that use snatch blocks on the anchor claiming there is mechanical advantage. Thanks for the demo. One note, the winch force or power is not increased. The load limit it is able to pull is increased by the mechanical advantage. There’s a slight difference but important to understand.

the only thing that makes this a "snatch" block is the fact that you can open it up to allow you to put the line on it rather than having to thread it through from the end of the line. In all other respects it's a regular pulley, and all regular pulleys will act as your "snatch" block acts.

You guys are crushing social. You're ahead of the industry.

I am also an erection as well as a mechanical engineer i love these video

There must be someone on this planet that can produce a video of a technical nature without the miserable unneeded distracting background music.

Thank you. Great setup and demonstration.

wait a second... isnt the capacity lowered further if the edge radius is less than the chain diameter? you dont mention that

Not very helpful at all.

Could you please drop a direct link to the "tool-less" locking pins for your shackles?

Nice example and too the point. Suggestion for using a swivel eye to get around the angle issue too👍

The eye with the tag always goes to the hook

I dont understand

Can u do a video for SCC? Bitte
