    How to: Move giant rock

    this rock has been in the middle of our trail for the past year and we finally moved the sucker to complete the road gap step up to connect the upper and lower section of the Sentinel.

    so if you cant sink it, and if you can't break it, winch it. we used a 5000lb come-a-long 2 tow straps and a whole load of safety straps. use trees as anchors with tree straps as to not damage the tree and be very cautious to secure all the straps so if something slips its either tied down or roped to.

    so heres a photo directive of how we moved it and the completed section of trail.

    the rock in question

    Nice man! That trail looks sick! Big boulders are a pain in the butt to move. Good idea!

    Nice work! And that's a big bench cut that you did by hand. Yikes!

    If you don't mind me asking, where is this? Also, why didn't you incorporate that rock into another feature? I'd love to have a rock like that here to work with.

    Lastly, check the cable in that come-along after a move like that. Watch for frays and kinks. An even better tool for that is a grip hoist, which offers a continuous wire feed but is very $$$.

    ya that is one of the bigger bench cuts on the trail wasen't to bad it took us about 8 hours with 3-4 guys to build the whole section. as far as the grip hoist goes yes it may be a better tool but we have a come-a-long and you said it your self grip hoists are spendy.

    we tried with 4 guys just to roll the rock over the edge when we had it close and it still would not budge. we tried using 2 6 foot rock bars and nothing happened so moving it and using it was not an option.

    thanks for the compliments guys the trail is smooth as butter!

    I agree with the suggestion to get some rock bars. Rock bars and come-a-longs work well together to move really large rocks. You can use the cable to tension and control the movement of the rock and the rock bars to encourage the rock to move where you want it to go. Only downside of rock bars is they are one of the worst tools to carry out to the worksite.

    Must be a privet forest then. Just figured it was a public area that you and your crew were improving.
