Small Jib crane for firewood bundles....

[Oldpath05]

I think this was plan D to lift and move a small-ish firewood bundle 6', if I'd got to plan F I'd gave up and bought a crane. Steel I beam is better, but the prime directive was to go cheap and spend alot of time, go through alot of aggravation and make a Wooden I Beam, and that's because there was a great lack of blueprints and no Youtube ideas. I go on youtube and seems like there's 10,000 examples and video's of jib cranes for cameras, a few floor space taking gantry cranes, but just TRY to get some ideas on jib jabbing. So I had to rely on three people that have no idea what to do, me myself and I and they all came to the same consensus, There will be no floor space taking gantry cranes in, at, on my garage.

First pic is I clamped the crane to the bucket, got it against the wall and screwed it, then a few more pic. to prove that wood can work. I estimated it to be capable of lifting 400 lbs. atleast once.

"at least once"!!!!! Hahahaha! That's funny right there, but good job to all three of you lol

Very nice! As long as the bottom "flange" of your built-up wooden I-beam is very well-secured to it's "web" you should easily be able to lift a 400 lb load. I hope you used lots of screws and and some good construction adhesive or strong glue to keep it attached under load.

Old P is that an old Husky 50 or 55 you've got in your hands? I had a dear and best friend pass away back in 1985. He gave me his hardly used 50 knowing he wasn't going to be using it much. Never met this man's replacement. I have this saw to this day and it is a working implement. With an 18" bar, it makes for a very nice felling saw.

That is a very nice construction. Me? I just would have built a shute.

I really like the concept - love lifting things with equipment instead of my back

This is just my opinion, but I'm pretty concerned about the screws pulling out.

Screws do good with sheer loads, not so good with holding a pulling load like your lever has created.

When they go, they likely will fail quickly.

Still, kudos for making cool stuff.

Lag screws need to be sized and installed properly in order to hold. For (say) a 5/16 screw, you can hope for around 300 lb of pull-out resistance per inch of thread depth. A few lags into a 4x4 post should hold the loads we're talking about here. The weak spot in this design is probably the bottom flange of that I-beam. If it is held in place only by screws, even long No 12's it could eventually fail under the proposed 400 lb load.

One of the biggest problems I had with working with just me myself and I, was no one could remember who did what with the blanking drill......

The Web is 1-1/2" x 5" x8' red oak, plane, the flange on top 2> 1/2"x5"x8' yellow birch boards>glued together,<<and that is glued and screwed with 4> 3" Spax lags to the Web. Bottom flange is 2> 1/2"x5"x8' boards>> where the trolley rolls<< thats 1/2" red oak with 1/2" yellow birch glued and screwed together and that was glued screwed to the Web with 4>3" Spax lags spaced out. I'd call the flanges to be homemade plywood, sort of.....

I was picturing to make it strong enough to lift 2 people who weighed 200 lbs each, but mu slab bundles are no ware near that heavy just heavy enough so I cant lift them by hand, estimating bundles to be 100-200 lbs, size is 20" long 24"x24" ish. This weekend I'll try to sneak out the bathroom scales when the wife ain't looking, try to get more accurate weight number.
