All depends on the loads and in this case the twisting of the load. I know I’ve welded more web to flange stiffeners than boxing in beams with plate, again which way is better, no idea! Would like to hear from an engineer’s point of view.

    How’s the new winch working out so far?
    Web stiffeners are in there behind the flanges 4 of them 2 each side of the beam.

    Hi Adam, Wish I could have caught you before you used the beam for the upright, A square tube would have been the best choice and to have used the beam on the top.

    Boxing the beam in will be better than webb stiffners, you were correct to have stiffners at the pivot points however.

    My next concern would be your anchoring to the cement, a footing is best, epoxy anchors are second and wedge anchors being my least favorite.

    I've installed a few cranes in my day and almost all manufacturer specs call out for footings with a anchor bolt cages.

    From my educated guess I would say the weakest link is your anchors in the concrete, Excluding the hoist.

    I dont mean to tear your jib crane apart more than likely youll be fine.

    Hope things are good with you. P.W.

    Good informative post, i like VERSALIFT, because this is a big dog in the bucket jib crane industry. They specialize in aerial lifts provided to telecom, utility, forestry, sign and lights, and a lot more. Thanks
