Excellent video ! I've used your shackles for decades never had a problem with any of them. Given a choice Crosby is always my first choice for hoisting work. Thank you for the factory tour !
Wtf! I walked past a crane yesterday, looked at the cable joint and wondered how long it would last, how it would be maintained and how you would assess when it needed replacing. Is Instagram reading my mind?
Such great work and information on an amazing process. Everyone involved are amazing people and it is such a great video! Very informational thank you.
I worked in crane repair in a steel mill. We never lubed the cables more than what they came with, which wasn't much at all. We changed them very often based on the number of lifts, but occasionally, our inspectors found broken wires, making those cables a priority.
The degree you are off is not usually exact. The idea is to make sure your lift is as level as possible so that you are distributing the weight evenly. There is tolerance there, but it is slight. A very slight tilt can be accepted, and you can eyeball that 5 degrees. Anything more than that can be dangerous. You don't need to be out there calculating how many degrees your load is tilting. The idea is to rig it so it is not tilting at all.
I am totally clueless. 😅 Here about chains info for exercise, and every time they talk about overhead lifting, I'm sure I was thinking differently than they!
Overhead lifting with chains means using chains to lift something off the ground from an overhead source, such as a hoist, a tractor bucket, a crane, etc. If you are lifting something with chains, it needs to be grade 80, 100, or 120.
Both would be synthetic slings. Are you referring to if it is nylon or polyester if it is a web sling? Or are you asking if it is a high-performance roundsling or a typical roundsling? Either way, all the information you need should be listed on the manufacturer tag. If it is not the sling should not be used.
Remember, edges can hurt chains and cables as well. Much more durable against abrasive surfaces, but an edge can bend a chain link or cut strands in wire rope causing those slings to be removed from service, at a much higher cost. It all depends on how much you are lifting and the edge the sling will be subjected to. Some simple protection solutions can improve safety and the life of all your slings or prevent damage to the load you are lifting. It is never a bad idea to have a few pieces of protection on site in case the need arises.
I'm in charge of inspecting these at my job. How does a person distinguish the difference between a knot made by the manufacturer and a knot (bunched up area) made by torn yarn?
There shall never be a knot in any synthetic nylon web sling. Single-path and Twin-Path slings may have what feels like a knot within the sling itself, but this is where the internal fibers are tied off and taped. The user shall become familiar with this during their pre-shift or pre-use inspection. Twin-Paths that use fiber optic, tell tails, or Check Fast systems will also have spots that feel out of place. If the internal fibers break within the Single or Twin-Path, they will typically “bunch up” in one spot, causing what may feel like a knot. Near this spot, you will feel something like a void where there are no fibers due to that failure. It is rare, but possible, that a user will find a catastrophic failure. I hope this helps. Please reach out with any more questions.
Gunnebo actually has its manufacturing facilities in Sweden and Norway and is part of Kito Crosby, so it should be readily available in Europe. Contact your distributer, where you buy your rigging, and they should be able to help.
Great video guys. Our cranes are being installed right now and I'm trying to gather as much info on rigging and slings as I can. You guys make it easy. Thanks so much for that!

No. This is unnecessary unless you have cause for concern that the crane is no longer able to support its rated capacity. If this is the case, though, other indicators found during the inspection should cause the crane to be removed from service while it awaits repairs.
