hello, I'm just setting up my welding workshop, I don't have cranes or forklifts, but for the heaviest jobs I would need a frame to hook up a chain hoist to set up a sturdy and effective temporary crane, modest capacity around two tons, with a useful height between 3 and 4 meters of useful height and a gauge of about 3.50 meters of gauge some useful suggestions thanks greetings.

any photos, any drawings to draw inspiration from? Thank you

The funny thing about building a gantry crane is the need to have a hoist to lift the main cross beam onto the A frames. That beam is a lot heavier than you think it is…

Also... Before building any hoists or cranes, check your local rules and regulations surrounding these.

In many areas of the world this kind of equipment is fairly heavily regulated or subject to approval/inspection before it can be put to use.

if you use an electric hoist it must be certified if it is manual and you use it it depends, I have no employees it is a structure that I will have to use, how do you advise me to conceive and build it economically? it must be light and handy to use and clearly robust to support high loads, thank you. better all H-beams or I can do a mix, the H-beam and the lateral feet in tubular and box-shaped, what do you recommend??

[cj737]

I beam across top, square tubing for verticals, angle iron for “A” legs. I beam for side legs.

If you construct it laying on its “back” then you can get some help with a few strong pals and a rigging rope to tip it up onto its casters. Casters will make the crane portable and useable. Constructing it properly is always the trick.

I found out if the device is equipped with an electric hoist with a capacity exceeding 350 kg it must be certified and accompanied by a project by a professional such as an engineer

I built a gantry by hand with no machinery assist such as a forklift. I did however assemble it, then used my F-450 diesel dually to stand it. Then added casters and later trailer wheels and tires for better maneuverability on uneven ground.
