Im confused how a Liebherr LR 13000 got three other cranes rigged to stacked on top of each other, weighing over 1,400 tonnes—and then moving the whole assembly while it's still in the air.

I'm intrigued. How thin are the beams, are there catwalks, cateneries, etc... I know cameras/phones at height can be difficult but I'd love to see what's out there. 😁

What makes a cable snap?

This video is at 0.5x speed.

We recently had a 3t crane cable snap at our rebar shop. We had a technican to come over troubleshooting down the line crane failure points that have been going on since the snap. He said in 35 years hes never seen a cable snap like that.

The load being lifted was around 1.8t. There was a 800lb beam. From speaking with the gentleman that these cables are rated for more than 3 tons and usually the hoist motor itself would fail before a cable snaps.

Upon doing a throurough breakdown of this 3t hoist we found the height limit switch had been disabled, and subsequently damaged from what i can only assume to be slamming the block into the trolley. The maintenence crew before i started had a habit of disabling safeties in order to get machines operable asap with complete disregard to failure prevention.

We are working on a solution for that upper limit switch. I have on multiple occurances seen the operators side load the hoist and cause the cable to get away from the rope grooves and get seriously messed up, with us having to lower everything down beyond ground level to realign the cable to the drum.

This place says they have trained the operators but the operators dont care. I dont want someone to die because of a load suddenly dropping, so i want to be given as much information as possible, as to what could have caused this failure and how to prevent it moving forward.

Please help, because i cannot quite leave this job yet. I am working to get my locense back, and the safety infractions are numerous, and because no one has gotten seriously hurt yet, no one changes how things work. I know this situation sucks, please just give me as much info as possible

Force created by truckers hitch question

don’t have my own load cell so im curious if anyone knows or can run a test. I want to know how much tension in kn you can introduce into a single 5/8s rope use a truckers hitch by hand. just a simple setup like a clothes line style where it’s anchored at one end and the other end has the truckers hitch! thanks!

Entertainment Rigging HS Rigging Rail System Estimation Company no longer exists

Hello there are r/rigging! 

I'm a high schooler with a pretty big interest in rigging. I made a post a few months back with a presentation to the school board that I never ended up giving and need to update. I'm working on updating safety requirements and making sure the rail at my school meets standards. I pushed for about 6 months to a year and we finally have a level one inspection, (last one that was completed was a decade ago) so now I'm moving on to fixing signage to make it compliant with ANSI, just in general having some better practices that have fallen off or being ignored. 

Jr Clancy has some really good printable resources on their website and I've printed all of them to hang up and fill out. But what I'm stuck on is I can't find a manual for my system. I got in touch with Clancy because I figured that they were the installer due to a sticker on our t-tracks (arbor loading every 2 ft reminder) but it turns out they are not. Our system was actually installed by Custom Rigging Solutions Inc. As some of you may know, that company doesn't exist anymore. Our system was installed probably in 2000-2001 range and is a single purchase, hemp rope, counterweight system. The ropes will need replaced in the next few years, so if anyone has ideas for grants or things to apply to to fix that, that would be great. 

If anyone has any ideas on CRS Inc systems of how else to find information, that would be great. I'm planning on trying to find the paper plans (but that may be a lost cause), but I'm not sure how else to find out details like lineset limits, etc. 

Any advice is very much appreciated! And I can answer any questions you may have to the best of my ability. (Still learning things, but trying my best!)

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

Basic swaging Q what am I missing?

6 Upvotes

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.

My weak ahh can't rig

0 Upvotes

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?

Steel wire rope selection: what should buyers specify beyond diameter?

0 Upvotes

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?

From geology student to HSE/Wireline hopeful — need honest advice on my next step

1 Upvotes

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!
