consiglio telaio gru a cavalletto per paranco o monorotaia fai da te per capannone

Ciao, ho pensato di dotare il mio capannone di una gru a cavalletto da usare nel caso in cui dovessi spostare pesi pesanti o caricare oggetti ingombranti sul pianale di un veicolo o nel cassone del mio rimorchio. Idee? Altezza utile sotto il gancio 3,50 metri, larghezza 4 metri, capacità tre tonnellate. Qualche suggerimento utile online, ho trovato alcuni video didattici, grazie

I recommend gantry crane frame for hoist or DIY monorail for shed

Hi, I've been thinking about equipping my shed with a gantry crane to use in case I need to move heavy weights or load bulky items onto the bed of a vehicle or into the bed of my trailer. Ideas? Useful height under the hook 3.50 metres, width 4 metres, capacity three tonnes. Some helpful tips online, I found some instructional videos, thanks

I've worked in several shops with DIY hoists like these. Problems were related to wheels too small, and short wheelbase.

Use large wheels far apart.

One of the auto wrecking yards around here has hoists using compact spares from cars for wheels. It works well on gravel.

I never liked the roll around cranes like that for several reasons. They take up a bunch of room, are cumbersome to move around on rough ground, and need 2 people to use effectively. I used one in a machine shop for loading parts and angle plates onto small boring bars for machining. The concrete floor was getting chewed up from the metal wheels. All other shops had moving overhead cranes or single post jib hoists. I installed a fixed 2 post 2 ton hoist in my building. Instead of moving the crane, I move the vehicle. It has worked for me.

Why do you even care, if the Italian doesnt care to translate it himself....

I have an IR air operated 2 ton hoist running on an I beam that runs the length of the main shop. I use it all the time. Great for oil changes on motorcycles, no more bending over. I use fabric machinery slings to hoist them up to eye level. I prefer air over electric just because I have plenty of compressed air available.

I see Harbor Freight offers a gantry crane package.

Get a used one of these with side shift for the same cost as a gantry crane. You will thank me later.

Not a bad idea actually but if I ever got one, would have to have other than solid rubber tires. I load and unload trucks at the shop but I use one of my M9000 Kubota's with the SSQA forks on the loader arms. Solid rubber tires are instant stuck on gravel or loose dirt. We don't have a loading dock anyway so everything gets side loaded and unloaded. Steel deliveries are the big PITA simply because of the weight of the steel but so far, the M9's have handled it.

If for some reason I had to load or unload something beyond the lift capabilities of them, the farmer down the road has a BIG JLG telehandler I can borrow and my SSQA fork set fit on his JLG.

I need it to load the wagon without unhooking it from the tractor for safety reasons and stability of the tractor trailer convoy, am I wrong as a precaution? underneath I will lay a concrete screed to make the surface harder and more compact and increase the load-bearing capacity of the ground. sorry for the translation I'm not very good greetings

Cute little toolroom / second operation lathe. Not much in the way of swing or overall bed length either. I'd say it weighs less than 1500 pounds (US).

If I were building a crane that would go off-road, I would get the biggest casters I could and gusset the connection between the top rail and side legs more.

Dovrei recuperare le travi per la trave orizzontale e le colonne per le gambe, che materiale e sezione uso trave e tubolare o tutti i profili H o U? che sezione. se avete foto o disegni utili vi invito a mandarli nella discussione grazie

(Should I recover the beams for the horizontal beam and the columns for the legs, what material and section do I use beam and tubular or all H or U profiles? What a section. If you have useful photos or drawings I invite you to send them in the discussion thanks)

I agree with most above, if going off concrete the biggest wheels available are very important, I think I know the salvage yard bcp is referring to and they do work real nice.

I have one but it has ~4" casters so it is limited to smooth concrete.

I would get the casters as far apart as reasonable and as high as you have available, two trollies and two chainfalls make it way nicer to use for most things...

I'm not sure what's commercially available in Italy but if you have the ability making something shouldn't be too much of an issue.

Acquistane uno usato con spostamento laterale allo stesso costo di una gru a portale. Mi ringrazierai più tardi.

dove tu case in Italia

Grazie, potresti gentilmente allegare delle foto con delle misure di riferimento? Per la traversa penso che userò una trave ad H da 180 mm o 200 mm, credo che abbia la giusta capacità di flessione. Ho guardato le tabelle. Per le colonne penso che userò un tubo quadrato o una scatola rotonda da 4 mm di spessore e 100 mm di sezione. Cosa ne pensi delle proporzioni per i rinforzi o i profili a T o L o U? Ci devo pensare. Grazie. La capacità delle ruote è divisa e distribuita per tre, non per 4, perché a volte una gamba verticale non poggia correttamente in piano. Grazie.

Never side load a crane.

Power hoists are nice for repeatable large loads. Manual hoists offer high precision adjustments.

Power or chain travel along the beam a nice feature.

I have a 5,000# lift with worn cushion wheels and a gravel driveway. When the ground is dry I have no problems with traction but I have to avoid wet soft ground as I only have 1-2" of ground clearance at the drive wheels.

When I built my shop I made provision for a monorail crane.I picked up the forklift with triple mast and side shift and I can go 16'. I can do everything the crane can plus a whole lot more with the forklift. You need really good and level concrete floors to use a gantry crane effectively. The crane idea is now history. A bridge crane can be handy but can't touch a used forklift price wise. Certified cushion wheeled propane forklifts are everywhere and dirt cheap.

Purtroppo non posso permettermi un ulteriore sollevatore, un carrello elevatore o un muletto telescopico, al momento devo arrangiarmi con quel poco che ho e che per il momento mi basta - devo arrangiarmi con le mie piccole risorse.
tornando al progetto, ho trovato il paranco manuale a catena in un negozio locale. Ho visto il carrello per la traslazione del paranco su internet. come trave orizzontale penso che un H di 200 mm sia sufficiente.
Devo dimensionare i cavalletti laterali ad A oa T rovesciata. Devo dimensionare le diagonali, i rinforzi ei rinforzi. Ho trovato le ruote ad alta capacità molto costose. Mi pare che un amico abbia detto che nel capannone c'è una trave monorotaia, vorrei gentilmente allegare foto del fissaggio della stessa grazie alla traversa del binario e ai pilastri scusa se ti disturbo saluti
