thats AWSOME!!! how much did it cost you in materials? I need one of thoes bad! I wish I could do the same thing but have a dirt bike on top :d my dad makes me store my sled out at someones farm and I even have to pay for it! that would be my solution!
LOL - you might not want to hear this.......$700. Metal was just under $500 total. The wheels ran me $150 - they are about $35 each. Then the rest is associated hardware - chain, cable, turnbuckles, etc. You could do it for a lot less than this, I used 3" x 1/4" wall tubing for the uprights and the bottom crossbrace, and then 2" x 1/4" wall tubing for everything else. The lift itself weighs almost 350 lbs fully assembled (in the pic) no plywood yet either, probably closer to 400 lbs all said and done. If you are not lifting a sled, you could do it for a lot less, probably around $300 with current steel prices.
Again, probably could have gotten away with a thinner wall thickness at times, but I say if you are going to do it, do it right, then you won't have to build it twice. It costs more to overbuild but I don't have to worry about it either. Everything has a redundant back up, double chains on the winch - ANSI Spec to 1000 lbs lifting, working strength doubled and tensile strength of 1780 lbs doubled. One is good - two is better. Double lifting cables, 1/4", good to 1600 lbs a side working strength, and 4000 lbs tensile strength. The turnbuckles are rated for 3500 lbs a side.
If I am lifting a 500 lb sled, all the hardware that I would use, should be rated for about 6 times the capacity of the load or around 3000 lbs. The cables, turnbuckles and the chain exceed that, the 3" tubing is used in car hoists, etc etc.
The other big thing is welding. There is a ton of welding on this. All welds bevelled and double passed on the uprights and gussetted, lots of triangulation, and lots of heat when welding. Penetrating a deep bead into 1/4" steel is tough, so if you don't know how to weld, get some help. This isn't something you want to practice on, if a weld fails, you could do some serious damage to you or your toys.
Hope that helps bud.
