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
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!!!! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OJjhkYwRsQk.html&ab_channel=jackytanski
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!
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
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.
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
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.
