    Seeing the real world application of picking up those huge logs is encouraging...and daunting. Pretty audacious to make a rig like that and have it work so well.

    There are literally a gazillion pictures of stuff like that in Labbe and Carranco's : " A logger's lexicon".

    My guess is a rap or two w a sledgehammer to set the points in beyond any bark , same in reverse to unload. Shouldn't be that hard.

    I've never seen any need to set tongs. Might be different proportions with smaller logs and smaller tongs than those big tongs/ big logs. I bet it worked pretty easily. Maybe a kick to loosen.
    If it looks like I asked a question, but put a period, it's probably a question.
    Don't know why I'm question-mark challenged online. 😀 New Year's Resolution, better proof reading.

    I never hooked up to anything nearly as heavy as those logs, nor with tongs as large either...but I have pulled some decent sized wood with tongs...infrequently it was some trouble to get a solid grip, but never was it hard to knock them loose.

    Probably right. Its all about the angles. Never the less the psi on those tips must be intense
