You can't see it but theres a deep gorge of a canyon in the timber ,I wish I had a picture of the finished bridge , it was a major accomplishment to build and an impressive bridge to cross.Wow, that took some thinking.

Yes its not far from the old Renfrew camp on the Gordon R. M/L ,just before Bugabo Cr. Its the only crossing of Gordon River after the Braden Cr. junction , until Tr.11is the the one that is just off gordon main?
That's my favourite rock dropping bridge.
The crew that rigged the system up are the product of mentors like riggers Fred Mcmurray Jack Messer Morris Trembly Bob Robertson Blondie Moxness Blain Hanna . If you look at the rigging ,they used two skylines and a block purchase on a spreader log to raise it . Everthing is a little over built to ensure nothing fails ,these guys take a challenge like this and just do it . Unfortunetly most of these fellows have left the industry ,and along with them goes their skills and work ethics .Seeing that excavator picked up and being sent across like that is truly amazing. Guess when you get the right people around, they can engineer just about anything. Not sure of the size excavator but had no idea that they could pick up a load like that. Must of had some good brakes to hold it back going down hill like that. Just can't get enough of the pictures you people have been so good to share. Hope you all have a good Thanksgiving Day!
I really don't know that much about excavators so I would only be guessing at the weight. The straps or slings that cratle the machine pass between the inner tracks and the track rails ,the 10x12 in. timbers would prevent the cable from cutting its self on the medal edge of the track rail the track rollers would keep the straps properly spaced .The two skylines are spread apart to lift the excavator without damaging the top or sides .The yarder mainline has heal blocks attached to a bridle that is attached to the spreader log to raise the sky lines. The haulback off the yarder has a block purchase hooked to the excavator to snub it down the hill and the winch on the line horse is being used with a block purchase to pull it in to position on the far side of canyon.Camptramp What size of excavator could this be, 25-30 tons? I notice they have blocks in front and rear of undercarriage,did they use the haulback on the front block, and what about the rear one? Which drum did this rope go to..
Thanks for pics and stories

tw Timberwest more Edinburgh crossing
i've built a few log bridges for machines to haul logs across streams and getting those right took some thinking the first couple of times, but DAMN this looks like a HEAP of fun....wow
