Good use of rigging, carefull or you will be giving Reg a run for his money..............

 

Enjoyed that.

Lovely riggin on this one David. I prefer steel myself. But wire rope, not chain!

 

But it's a lovely choke point nonetheless, and a job well done no doubt!

one thing I can't be accused of is not having patience

 

6 years on and we finally had a job worthy of hiring one in for.............

Hi David ,

Really neat job mate.

We're just starting out but we're really busy. We're only able to do the most basic forms of lowering at the moment. I look forward to the day when we can work to that sort of standard and technical ability. Any tips ??

Thanks

Cheers, glad you got something from the vid.

 

The videoing works two ways, both as a way of showing what we're up to but also as a constructive way for the team to appraise/review a technical job afterwards.

 

as for tips, we're still learning.

Just building on experience and equipmment and applying those two things when we get the chance even if we have to make that chance, all in the name of progressing our skill set.

 

we played with the rigging idea in the yard a few weeks before and applied it on the job after a bit of tweaking.

Cheers Jon,

and went pretty smoothly.

 

No helmet footage of that pick, but it went straight up and away.

 

10 picks in all, a couple that were learning curves, a few went really smooth and the rest were the bits in between.

 

 

 

out of interest, why wire rope & not chains?

That's a very impressive rigging setup David.

 

Your's is the best vid of such a system I've seen to date.

 

One of my most challenging removals demanded such a speedline/lowering/lifting/haulback line combo.

 

When you have a tree growing over the L of a bldg, in my case The Torrey Pines Golf Course pro shop, and they don't want any one on the two story bldg's roof? No crane access! Only one line of sight out from 80 feet up

.

Enter the traveling speedline/lowering line, which takes 3 rope men working together in an extremely coordinated fashion to run properly. It really is one of the coolest rigging systems ever.

 

Congrats on such an excellent demonstration of a complex system workin it's magic mate!

Why wire rope rather than chain for heavy lift crane removals?

 

Like steel chain, wire rope stretches very little if at all. This is why steel's my buddy.

 

But I'm just a wee bloke who's been tasked at times with thousands of crane removals.

 

Chains are too heavy for aerial work being performed by wee tykes. So I use wire ropes and sliding steel clevisses on my big picks, just cause I'm a weakling yu see?

[David Humphries]

thanks for that Jon.

 

Cool shot, how many tonnes in that Euc?
