Saw a pretty cool column derrick in my travels, installing a water tower. Had my wife take a picture, let me tell you she was as thrilled as i was :lol: Sorry about the dirty windshield, the bugs have returned.

Yo, Kyle :).

Here's some pics of another bit of big weight moving. I know I posted these and the whole story somewhere here, but danged if I can find that thread to link. So I'll repost a few pictures for your perusal :).

Best estimates put the weight of the boulder within a few percentage points of the Chevrolet 1500. 5500 pounds-ish. Only way I was able to move this was pulling downhill, otherwise the truck would have been the more moveable object. Also had to chock all four wheels and stand on the brakes during the pulls.

Winch is a Warn 12k. Only needed a single block for this setting...so 2:1 ma, less friction.

As you can see from the pictures and the spin patterns on the gravel, I reset the rigging multiple times to keep turning the rock farther off the roadway rather than just a straight ahead pull. Frankly, that was the only special challenge here. Otherwise, I would not have been able to get it sufficiently clear of the travelway...just not enough room to place the truck for a straight on pull.

I won a $50 bet on my being able to rig and move this one solely with my truck and winch. From a master's degree road design engineer :D. He was fairly new to the Mt. Hood NF at that point, didn't know his opponent's skills well yet :lol:.
Yup, these are the photos that I remember B! Wasn't sure where to find them.

This is one of my fav ongoing threads on the TH.

Thanks again!

Fun grocery trolley from a bit ago. Apparently rigged by a ship's captain for his cottage. No lugging stuff up the 30 foot staircase. Was apparently water powered at one point, now electric winch. Oh yeah , the house is chained to the rock too! If you like rigging, you solve problems with rigging!

We use this system, or a variation of it for moving debris. Doesn’t happen often but it’s a huge help when we do.
We refer to it as a tensioned high line, get a high line set at the debris end and tension the landing side with a ute. Use gravity to slide load to the landing.
Here’s a small light weight version I used to get a load of firewood.
There wasn’t any suitable back spar so I had to be pretty gentle with the loads. Heaviest was probably only 300kgs but that was pushing the back spar and the WLL of the high line to it’s limit.
Sometimes use a haul back line to slow the load down or just to make getting the trolley back up the hill easier.
