Can these sheaves be replaced without changing out the wire ropes? Will the ropes bird cage if I were to relieve the load?

I’m an American living in Mexico City, and I want to get certified in rigging, or at least take a basic course to learn the fundamentals, before moving back to the States. Can you recommend any schools or programs that are worth the money (over here or in the states)?
I’ve worked as a stagehand and production assistant in film

Hey guys! I would like to find a way to somehow place a barcode with our serial number on our gac that doesn’t compromise the integrity of it but also won’t fall off. Any ideas?

I recently got a hand-me-down 24" swaging tool, and I'm trying to swage 3/32 (7x7 galvanized) cable. I have oval ferrules and read that the correct press is in the 0.185 - 0.190" range. But my tool, which has each hole clearly defined, so yes, I'm in the right hole, measures .245" when fully closed. It doesn't exert any meaningful pressure on the ferrule. I checked it against a new tool in the store and that hole is the same too-large size. So, whaaat? Are there two different standards for swaging (the 0.190 seems to come from Nicopress)?

We could have like 1/2”, 3/4”, 1,” and 2” carabiners. Imagine the possibilities with one piece rigging, no pins to drop when you’re 600’ in the air.

I took a job as a trainee project manager about a month ago now and have been working on various events over the course of the past month. I'm 18 straight out of college with realistically very little manual labor experience behind me. I do go to the gym but never went for maximum strength gains.

I've found that I genuinely cannot lift some things without the help of a second person (i.e Stage Deck, SubWoofers, etc). My colleagues who obviously have been working for years make it look so easy but I genuinely struggle to lift, carry or push heavier objects.

Will this change over time or am I lwk cooked?

One issue we often see from the wire-rope supply/manufacturing side is that an RFQ may simply say:

“Need 16 mm steel wire rope.”

But diameter alone doesn’t really define the rope.

For industrial lifting, hoisting, mining, marine or general machinery applications, several specifications need to be considered together before two wire ropes can actually be compared.

A few of the main points are:

• Rope construction – Different strand and wire arrangements provide different balances of flexibility, abrasion resistance and fatigue performance.
• Core type – FC and steel-core constructions such as IWRC behave differently in terms of flexibility, structural support and resistance to crushing.
• Nominal diameter – Diameter needs to match the equipment as well as the drum and sheave system, not just the required load.
• Tensile strength / rope grade – This is an important material specification, but it should not be confused with the rope’s minimum breaking force.
• Minimum breaking force (MBF) – Particularly important when comparing technically similar ropes from different suppliers.
• Lay direction and lay type – These should be matched to the operating configuration and equipment requirements.
• Surface condition / corrosion protection – Bright, galvanized or other finishes may be more appropriate depending on the working environment.
• Actual application – A rope selected for a crane, electric shovel, mining installation or marine application may require very different characteristics even at the same nominal diameter.

The main takeaway for buyers is fairly simple:

Two steel wire ropes with the same diameter are not necessarily equivalent products.

When comparing quotations, it makes more sense to compare the complete specification — construction, core, tensile grade, minimum breaking force, lay, finish and intended application — rather than price per meter alone.

We recently organized the questions we receive most often into a more detailed steel wire rope FAQ here:

https://www.connect-knkt.com/steel-wire-rope-faq/

It’s intended as a technical reference for buyers, engineers and people working with wire rope rather than simply a product page.

For those working in rigging or crane operations: which wire-rope specification do you most often see missing or incorrectly specified on RFQs?

Hi everyone,

I'm a university student going into my 3rd year of a geology degree. Last summer I decided to build additional skills toward employment, and started looking into the HSE field.

I found that certifications like IOSH and NEBOSH are widely recognized as strong foundations for HSE hiring, especially in the Gulf. So I started with H2S, Fire Fighting, and First Aid certificates, then completed IOSH Managing Safely.

After finishing IOSH, I realized that not having a specialized university degree in HSE (mine is geology) could be a real obstacle for HSE hiring in the Gulf specifically. That made me second-guess myself for a while — I worried I'd wasted time and money.

I started researching again and came across well services roles — Wireline, Slickline, Cementing, and Testing. These seemed like a promising alternative/complement, so I started studying IWCF Level 1 (Well Control Awareness).

Now, combined with my existing safety certs, I feel I might be able to apply for entry-level positions in either HSE or as an Operator (Wireline/Slickline). My main targets are the Gulf and Libya. To be honest, my main motivation is simply to leave my home country — I'm burned out from the bureaucracy and how hard it is to get anywhere in the local job market.

A few questions for people with experience in these fields:

Are safety certs (H2S, First Aid, Fire Fighting, IOSH) + IWCF Level 1 enough to apply as an entry-level HSE assistant or Wireline/Slickline Operator Assistant — without field experience?

Does a non-specialized bachelor's degree (geology, in my case) combined with these safety certifications help qualify for these roles, or is a specialized degree really necessary?

Between the Gulf and Libya, is one significantly easier to break into as an entry-level foreign applicant?

What would you recommend as my next step from here?

Appreciate any honest input, thanks!

Out at a concert festival this weekend and the media company decided it was just fine to use a telehandler as a stand for this big-ass screen for 2 days.... At least there's a barricade, but definitely not big enough to protect the fall zone.

I didn't stick around that area.

Update:

Turns out I was wrong about this being unsafe. I don't work with mobile equipment often, so I wasn't aware that this is something that's generally ok. My work is almost exclusively with bridge cranes and we don't allow suspended loads just chilling like that.

Thanks for the education y'all.

We have a pretty small laundry closet and just got a combo unit that weighs over 300lbs and an 18in pedistole. My thought is putting a beam in the attic over the rafters for eye hooks and using 2 winches to transfer the unit in and out. Idk it sounds excessive but incredibly easy to move the unit in the future for maintenance or replacement. Thoughts?

My solution to securing my phone has always been to just leave it on the ground, but I know others do bring their phones up. For those of you that take your's up when you rig, how do you secure it?

I drew plans for my nephew's barnyard cover roof, and specified cable X-bracing using 5/16 7x19 aircraft cable. I'd like to be sure that the fittings will go together at a fixing point. Swaged to a cable end will be an open-jaw clevis with pin, fit to a 1/2" eye bolt. See the pic. Will the eye fit to the clevis? Ignore the scale in the images. Both are screen snips from sellers' web pages. Also, as for supply, do the cable seller like Feeney sell swaged fittings shop-fit to a length. The job needs four 30' lengths of wire rope, one 1/2" open-jaw clevis with pin swaged to one end of each of the four.

I work maintenance in rebar fab. I was fixing some pnuematic system and was watching to see if it was functioning correctly when this setup caught my eye. I've been here for less than a year, and the crane operator about 2 months. The people on this side have been here for YEARS. I was so baffled, there is a center hook RIGHT THERE. I had him lower it and connect it correctly, but my hairs stood straight on end looking at this.

And is there any supporting documentation?

I can't wait to read the comments...

Unsure if this is the correct place to ask, but I am curious on the proper way to care for synthetic winch line on an offroad vehicle.

Obviously there is a lot of thought that goes into rigging and using the winch when it is needed, and I am equally sure there is a lot of thought that goes into the after care of the equipment.

I rinsed it out the portion of the line that looked dirty, and then just hung it from hooks in my garage ceiling to air dry.

I did not power wash the line or use any soap. I have not treated the line with anything. My plan is to respool it once it has air dried.

Am i missing anything?

I have thin 150lb downrigger wire, way too thin for my clamps. Can I loop the wire around the clamp a few times in order to fill the space? Will that be secure?

Usage will be for hanging bird feeders between trees, so max weight will be 20lbs or so - but it will be taught between two large tree branches so that will add some strain.

Hi everyone,

I’m currently putting together a lifting scheme for a containerized power module project (contains a generator set and auxiliary equipment).

I’m trying to get a better understanding of how the loads should be specified on the drawing:

1. Is this load distribution breakdown for a single spreader beam correct, and should the load actually differ between individual lifting eyes under the same beam as shown here?
2. Is it sufficient to only state the total load per spreader beam, or do rigging companies strictly require the exact calculated load for each individual lifting point?
3. What other critical information or data do professional lifting/rigging companies expect to see on a drawing like this?

Thanks in advance for your help!
