There is no black-and-white answer to this question. This is what our inspection manager, Tom Horner, who has over 26 years of experience performing inspections, had to say. It is never recommended to paint a synthetic sling. However, it is correct that no ASME statement specifically says you cannot do this. Ultimately, it is the inspector's duty to determine if the paint is, in fact, an issue. A light dusting from overspray is probably not an issue, but has the application of their paint caused other issues, such as stiffness or a lack of flexibility in the sling? I have failed synthetics due to this, which is most notable for paint shops and paint booths. We highly recommend never painting a synthetic sling simply because it is the introduction of a chemical. We also do not recommend the practice of marking your slings to show that they have been inspected. Here is a link to an article that gives you 7 reasons why marking your slings with inspection tags is not making your lifting program safer. www.mazzellacompanies.com/learning-center/7-reasons-inspection-tags-arent-making-lifting-programs-safer/

@@LiftingandRigging Thanks alot

Portal Crane is another name for a Gantry Crane.

Glad it was helpful! Thanks for watching!

For some, it may not be. For others, making a ton of picks a day with loads that are challenging to rig evenly, this can help speed up the process. It really just depends on the work you are doing.

Thanks for watching! Glad you found it useful.

@@LiftingandRigging sure 💯% I like your channel

So, I'm not sure exactly what you are asking, so I have two answers for you depending on what you meant. If you are saying you hand-splice a sling and then put a carbon sleeve over the body of the splice, then NO. You don’t want to do that. We have already performed the “splice by opening up the s strands and 3 strands + core and performed the splice back onto themselves, forming the eye. We then have small tails on the Mechanically spliced sling that get tucked around the neck, and the carbon steel sleeve is pulled over them and hammered into place prior to putting them into the swagger. If you are asking if you can have a sling with a hand-splice taper and conceal eye on one end and a mechanical splice eye on the other, then YES. That is being used quite heavily with ironworkers to have the mechanical splice eye in the hook of the crane (the same end that has the tag on it to protect the tag from damage), and the hand-splice end is being used to choke the load and does not have a carbon steel sleeve on it to obstruct the slings from pulling out from under the load easily. So recap - Do not put a carbon steel sleeve on a hand-spliced taper and conceal-eyed sling. But you can have different style eyes on the ends of one sling.

Thank you for good explanation​@@LiftingandRigging

Our pleasure!

Getting roofing tar on your harness, lanyard, or SRL could interfere with its proper operation. Therefore this is a cause to remove from service.

Glad to hear it. Thanks for listening!

Nice chatting with you today, Jack.

A great skill!

Most slings are proof tested to 2 times WLL before they go out. Technically an overpull would not pull the sling from service unless afterwards it does not pass a visual inspection. The key thing to remember here is that you do not need to pull test slings as part of a periodic inspection, but having a competent and qualified person perform and document those periodic inspections is required and very important. All employees using the slings should be trained to perform visual inspections daily before the sling is put into use, and they should be trained to spot removal criteria at any point during a shift.

@@LiftingandRigging Yes, that is how we operate. But some "expert" in our department is pushing annual 200% Load Testing. 🙂

​@@robbyburty If you would like your slings load-tested, you can always send them off to Mazzella, and we will be happy to do that for you. It is not a requirement as part of a periodic inspection though. A better practice would be to hire a 3rd party who specializes in rigging inspections to perform and document your periodic inspection. Mazzella would be more than willing to help with that as well. Here are some more resources on rigging inspections that you can share with your team. www.mazzellacompanies.com/rigging-inspection-services-resources/ You can always reach out to our inspection team here as well. www.mazzellacompanies.com/company/contact-us/contact-rigging-division/

One thing to keep in mind here is also "load test" vs "proof test." Synthetic slings are not proof-tested. Proof-testing them would be like you said, an overpull. Not great for a synthetic sling. Many synthetic slings are also batch-tested as the slings are manufactured to a proven process.

Industrial Training International is able to help you get certifications. They are a partner with us. www.iti.com/ They are a partner with Mazzella, so feel free to work through us. www.mazzellacompanies.com/liftingu/iti-training/

Doesn't sound OSHA compliant.

@LiftingandRigging 3 wraps past the junction point is what I've been told. I've never used them around OSHA but MSHA inspectors have always approved them.

Devon no longer works on the Lifting & Rigging Channel, but thank you for digging into our library of videos. I hope you find that the newer videos are at a better more understandable pace. -Ben

@@LiftingandRigging Ben, Thanks. Your Method of Teaching is quite amazing.

Most, if not all, wheels used in underhung applications these days are dual-type, flat and tapered. This allows them to be used on W (flat tread beams) or S (tapered flange beams). However, when dealing with patent track, the wheels need to be designed specifically for patent track (they will be made of hardened material) and will always be flat.

@@LiftingandRigging Thank you. Keep up the good work!

Thanks for watching. Appreciate the kind feedback.

Most monorail cranes use an underhung system and fall under ASME B30.17. The process of purchasing a monorail crane will be the same as that described in this video.

Glad to hear that! Thanks for watching!

Great question. I would suggest a mobile fall protection system. There are several options out there including one that we have done a video on in the past, the XSERIES Mobile Grabber by Malta Dynamics. What they refer to as the "hook in the sky" providing fall protection where there is no anchor point. Feel free to check out the video/article here www.mazzellacompanies.com/learning-center/what-is-the-xseries-mobile-grabber-mobile-fall-protection-unit/

Glad it was helpful! Thanks for watching!

I see what you did there. Nice.

Are you asking if there is a similar product to tighten turnbuckles?

@@LiftingandRigging yes I apologize. That’s what I was asking. I seen a power tool with some type of device that goes on turnbuckles and loosen and tightens it. Would you know the name of the tool

Yes. ASME B30.9 requires a design factor of 5:1 for synthetic slings. ASME B30.9-5.6.2 Proof Load Requirements (a) For single- or multiple-leg slings and endless slings, each leg shall be proof loaded to 2 times the single-leg straight-line hitch rated load. HOWEVER, you should never load any sling or piece of rigging hardware past its Working Load Limit.

D/d ratio is important and should always be taken into consideration. For complete information on D/d ratio, please refer to the website wireropetechinicalboard.org. The rated capacities of grommets are based on a D/d ratio of 5:1, where “d” is the body diameter of the finished grommet. You should consider a reduction in WLL for anyone using a cable-laid grommet with a D/d ratio of less than 5:1.

@@LiftingandRigging thank you very much, it's really kind of you, Appreciated 👍

2.6 t - 6.8 t depending on the size you are looking for.

Thanks for watching!

We'll get to work on that for you. Stay tuned.

Marine is definitely one of the best applications for the SS 316 turnbuckles. Corrosion resistance is of supreme importance in marine applications. Really, it's anywhere with water. Wastewater treatment plants, for example, are places where they get used frequently. 2nd to Marine applications would be hazardous chemical places. The chromium-nickel alloy has resistance to many chemicals such as sulfuric acid and phosphoric acid. On another note, these can also be used in high-heat situations. The SS 316 turnbuckles are suited well for high-temperature applications as well. We do see them used a little bit in construction.

Congratulations! As you are getting up to speed be sure to let us know if you have any questions.

Great point!
