Hang on, Powder Puff!!!
No joke, after the initial do's and don'ts stern training for safety's sake, they can find more ways to entertain themselves than you can shake a stick at. Our rider lawnmower, welding bench, or anything else not bolted to the floor has gone airborne.
The truck is coming along well. Congrats

I can see things heading that way!

I'll be pulling my 305E off the trailer in a couple of days. After that I'll be looking for new and innovative ways to get into trouble

I too had been dabbling around with the idea of getting a shop crane/cherry picker. About the time I was doing the shopping, Fetch ordered his and it wasn' much more than a week later that I decided to also order the 2 ton Harbor Freight Deluxe Racing Shop Crane. It should do everything I need it to do with heavy "stuff" including big tractor wheels, small engines, my Aunt Bertha and I figure it would probably move a 305E if you were careful. Harbor Freight was also offering the "Once in a life Time Sale", and I also found a 25% off coupon, so there ya go. Bout $170 out the door.
The steel framing and the welds and the fact that it has cast steel wheels instead of rubber/plastic are all a plus for that price, but I wasn't real happy with the low grade bolts. I mentioned this to Fetch while he was quietly waiting for his damaged box of parts to be replaced. So I went on a search for some higher grade metric bolts. Many of the assembly bolts are metric grade 4.8 and a few of the bigger ones are metric grade 8.8. So I figured to bump them all up to 8.8 and 10.9 respectfully. I found the info I wanted on a metric grade chart that lists their stensil strength. I don't know much about "stensil", but I'm all about having "strength" for this project. After many days of looking I can tell you that these bolts are NOT to be found at Ace Hardware nor NAPA nor Home Depot nor Lowes nor Tractor Supply. But I did find all that I wanted and more by going to

. They have it all. Sizes, strengths, different plating and fairly cheap shipping. I ordered up a replacement batch of all thirty four bolts and it came to about $50. Since the colors of this Racing Shop Crane are Grey and black, I went for a complete set of flat black coated racing bolts, and got some lock washers for the set, as none come with the Harbor Freight package.
There is one more thing I changed somewhat, and if I can ever figure out how to post decent pictures, I'll chime in and show you. It's a feature that would enhance any decent Racing Shop Crane. In conclusion I'll say it's really a sad thing to let a persons mind flounder around on a 4 day rainy stretch with no project to focus on. Look what happens.

Thanks for all the rainy day footwork Foley! I went with SAE bolts instead because most of my tools are that. I think we made good choices and I'll sure feel better when I'm lifting heavier stuff after this.

I'm all about "more is better" and all that....
But the shear strength of the factory bolts on that hoist are so much more than the rated design calls for that I might have spent the cash on something a little more rewarding.
The bolts that are used on the lift cylinder (both top and bottom) require the highest shear rating of any other on the hoist. Because of the application, the shear requirements are cut in half (it is exposed to shear effects twice, once on each side of the cylinder ram) so we can double the rated capacity for a safe working load.
Theres always some smart guy just waiting for a chance to armchair engineer yer project.......aint there.
But of course, when using the lift for hoisting personnel, the safety factor is X4 of the calculated SWL.......so I'm not even sure if grade eight is enough for the Powder Puff pick.

I read that the max load for safety is /3 for shear and that ends up being about 300 lbs shy of the max load of the picker, that's why I was pretty sure Id want my bolts upgraded. Plus this is probably all chinese junk and you never know what youre getting there. I might not have *had* to do it, but for $38.00 I know that the frame will bend before the bolts do. That gives me a little piece of mind especially with the Powder Puff working right along with me so often. I just don't want to worry about her getting hurt. (Ever! but I'm paranoid

Maybe youre right about going to grade 100 or something!
