who has the best combination of shall we say strength to weight ratio for pallet forks?

That would probably be Artillian.

The 2300 pound (capacity) frame weighs 73#. With 36" x 3" forks that weigh 112 pounds the total would be 185 pounds. The 42" x 3" forks weigh an additional 8 pounds putting you at 193 pounds total.

While these are likely the lightest and one of the best designs out there, they are also one of the most expensive. There are other options that are lighter on your wallet.

 

Considering the lift capacity of a 1 series, I went with the HLA 900 LB Cap. - Light Duty Pallet Fork

The price was reasonable also, around $495 with 42" tines as I recall.

 

I got forks with mine when I bought it, I think JD sells Frontier brand. You shouldn’t have any problem with 350 lbs.

 

Most used attachment for my tractor. I bought Artillian/42, as they are very light and have other uses. They are also expensive. I'd compare weights and versatility of the frame vs cost. Forks are like having 2 or 3 really good friends, and you don't have to buy them lunch.

 

Artillian's are the lightest, and they are made in the USA.

I chose Titan forks because they were half the price (slightly less than half actually) and the frame is only 20lbs heavier. Absolutely no regrets, they work great.

 

I have the Titan with the 42” tines. Perfectly adequate for the price. You’ll have no problem snatching your 350 lbs and more to full height.

 

Thanks for all the info. In looking the options over, I like the Titan with the headache rack and front 2” receiver. Of course, they are out of stock for online ordering. I’ll call them tomorrow and see what’s up.
