Mister Crane, my latest creation

[densie 20352]

   The story is, Im not supposed to lift anything over 20# or do anything strenuous, but I havent been able to give up playing around with cars, so I built Mister Crane to remove parts and carry them around.  The only problem now is that its kind of hard to push around in the soft sand, or over humps.   I have a small towbar that I may attach to it so that I can push it around with a garden tractor, or I may make it self-propelled.  Hmm...

Youd better watch out, it looks like hes trying to snatch your compressor!  Looks like hes already made away with your hood. . . Doug

Look in your phone book under "Material Handling". Somebody probably has "Beach" type wheels to fit your crane. I have a pair on my handtruck. They also make them to fit wheelchairs! I put a set on one. Also, have you Googled "surplus 12v motor"? Be amazed! I used to get catalogs in the mail (remember mail?) all the time for surplus industrial stuff. Then I got old.
BTW, Mr. Crane is way cool!

Go to this website. You wont learn much about twelve volt motors, although they are used heavily. You will laugh hard enough to be inspired once more! http://www.sashimitabernaclechoir.org/Construction-more.html

I think youre playing with fire when using pneumatic wheels when dealing with lifting heavy and often unstable weights.  If the ground is so uneven that you have to resort to this type set up, how are you going to keep it from tipping over if a wheel goes into a depression or a signigicant rise in elevation? A 750 pound engine/tranny combo, raised high enough to clear the height of the radiator core support (which is already raised >12" higher for the pneumatic tires to clear the undercarriage is just asking for someone to get hurt and something to get broken.  A collective Oh S**T! will sond if the tip of the boom tilts too far left or right or the center of balance of the suspended weight or its momentum yanks the whole kit and kaboodle onto the ground.

Nice thought process, but Ill stay clear and come up with a better way to lift.  Thanks.

....That is it you plan on lifting "heavy weights".  Using it for light duty shouldnt be a problem. (Suggest investing $600 and having a cement pad poured so you can easier get around, creepers, cranes and what not.

  I love the part about driving into the garage with the soloist up and decapitating him.  Ive already done that with Mister Crane...WHACK!

  The last extension boom has a tested weight limit of 100#.  Thats where it begins to bow, but is still elastic to the bending load.  I wouldnt be crazy enough to lift an engine with that part of it!

  Heavy weights like engines have to be lifted on the center boom, then they can be lowered onto a little table that I attach to the front legs.  I lifted a big television this way...set the weight down on the legs so that it was nice and stable and then I could move it around with no problem.
