r/Rigging

Plan: 1) Bottle jack it up 2) 2x4 tracks + 5” PVC rollers 3) Pull it with snatch blocks anchored to screw-in ground anchors. Does this pass a basic feasibility test, or is it a bad idea? Not asking for a full design—just a gut check. Appreciate any thoughts.

Hi everyone!

I am 20F and looking to switch careers to become a rigger. Is there anyone who has done this traineeship or is a rigger in Sydney who can provide any advice? I have not had any experience with this beforehand and am not sure what I could be getting myself into so just looking for a better idea of this job.

Questions:
- is it a very difficult traineeship? Do they expect you to pick up things really quick and study outside of the working hours

- how is it structured?

- what kind of person would not enjoy this kind of work? I get that it's mostly outdoor working in all weather conditions, but is it really tough and difficult at times?

- what are the working hours? Is it a 9-5? How many hours and what are the start and finishing times

- anything you wish you knew before you started?

- what is the salary during the traineeship, and then progression afterwards?

- is it a stable career?

- is there work life balance, flexibility with leave?

- what are other potential jobs you can go into afterwards?

Thank you everyone :)

I’ve been looking for info on this but haven’t found anything quite discussing what I’m trying to find.

Is there any merit to the concern that dynamic shock-loading of a round sling (continuous polyester jacketed) can damage the core without apparent damage to the sling exterior that would be seen in routine inspection? I found some mfg guidance once that discussed de-rating round slings based on hook speed (ie they considered fast hook a dynamic loading scenario and called for I believe 50% de-rating), but not this specifically.

Ie if a sling has been used in a non-standard operating environment where it was subject to repeated heavy shock loads, but displays no apparent signs of damage, is the sling stiff safe to use? This question is entirely theoretical and I’m looking for a technical explanation, not ‘if in doubt throw it out’ which in real safety terms is probably the wise move.

thanks

Hi all,

I have a question regarding swl of schackles on tugboats and would appreciate your professional opinion on the following.

Apparently it is normal practice to cross SWL of schackles in tugboats operations. Since schackles usually have a safety factor of 5-6 breaking load would be 5-6 times SWL. What happens is that tugboatowners hold a safety margin of around 3 times SWl, so if a schackles is rated at 85 tons you can use it until 3*85 255 tons pull in towing operations.

This surprised me. Can the community here give their wisdom on this practice? I would appreciate it. Is this normal practice? Is this done in other industries?

Thank you.
