Dormant hero!!
ok steve, the pink thing is the yarder
green line is a guy line
blue is the sky line
red is the skidding main
grey is the carriage
black is the choker
brown at the bottom is a stump and the brown in the middle is a log
engineer tightens skyline, then feathers brake (brake controls drum speed) for skidding main as the weight of the carriage (which hangs from sky line by 2 pullys) is unspooling drum on the way down the hill. there are 2 "clamps" in the carriage, one will clamp to the sky line and the other to the skidding main. if you want to stop the carriage along the skyline then you activate that clamp, at this point you can release the skidding main clamp and pull slack through the carriage. when you want to pull the logs in the engineer winds that drum in puling the logs towards the carriage, when they get close the skidding main clamp is activated and the skyline clamp is released allowing the carriage and logs to be pulled up hill. clear as mud?
