dimensional board for pillar and cross-platform

[odisseo 18]

hi, I should size a column and a cross to make a small-volume flag crane. we will want anchor through plates and threaded bars the flag column to a pillar bearing size 60 x 60 cm for a height of 5 meters. the foot of the plant will want to fix it on the ground through pins dowels to the foundation beam
The dimensions are:
flag arm 3,50 meters
height under hook 3 meters
capacity 600 kg
rotation angle at least 180 °
if it is possible we will want advice on how to achieve the support hinge, flag / pillar, which section use x various building elements thanks

how to size the knot hinge?

I would also be interested in having that answer.

If you're at school, you can talk about it. if really there is then to manufacture the crane, since it has to be certified, I highly recommend to buy it already ready from the various manufacturers certified intalians or European.
if undersized can get hurt or die someone.... Think about it.
you do not improvise designers less than lifting equipment.
However there are already discussions about the flag cranes on the forum.
At least the eurocode 3 must be used in the verification of hinges and beams as well as dyes.
the tie rod with threaded bar is to be excluded a priori because there can be hard snowing in the bottom of the hazelnut. better the bar with the pins at the extremes.

just to have a pattern on which to make reasoning we randomly have a couple of documents of academic analysis of flag cranes.
First you calculate the reactions and then you need to check the beams, welds and bolts. later it will analyze how to make the lower hinge which will carry axial and radial load and the upper hinge which will only bring radial. you will have to disturb the theory of end pins, axial and radial bearings, as well as the theory of pins replaceable by eurocode 3.
definitely a fem analysis could help determine the weak sections and see as a result of localized reinforcement effects on tension and deformation.

a solution with less friction and longer duration could be possible to establish bronzines in two roller-adjustable bearings, maybe axial or two different families, one above and one below and make verification with the skf tool.

if you go to the demag site there is the configurator and you can have his dwg that the 3d of the flag crane. in this way you will see the size of the beam and pin elements. Clearly demag uses a proprietary profile, but at the same inertia you can find a commercial profile and reproduce the thing.
Of course, structural audits in accordance with the norms, fems, risk analysis, harmonised standards and specific standards for cranes.

igo catalog pdf of the demag so you start to give it a look.... there are many info to know how to read well.
