I bought one of the Titan sets off EBay. [...] I don't lift things frequently, but when needed, they work great.... for my use....
That use is considered "light use". I have lifted a full 55 gal drum off of the truck, lifted 16- 4"x6"-8' pressure treated posts, carried / moved pallets with 4-500 lbs on them. [...] If I had to use forks on a daily basis... well I would get an SSQA set of forks.
The bolt ons are ok for those occasional uses
I also have a Titan set, without the stabilizer bar. I have the same experience.
Great to have around for moving a pallet with something on it, lifting stuff out of a pickup truck, etc.
But given the geometry, don't expect to pick up anything remotely close to the nominal lifting capacity of your loader, a number reflecting capacity at the pins, not several feet out in front, pinching the bucket at one point.
I've seen people who have put a divot in their bucket through carrying excessive weight on them. I'm being careful, and I have a heavy duty bucket.
I've learned the hard way to keep the screw lubricated and to unmount them at end of day: they can get semi-stuck if you leave them on too long, tightened. Nothing you can't get off, but it's no fun on a rainy, November day when you need the loader for something else.
In case useful to anyone, I do have a screwed-on Piranha tooth bar on the bucket. The forks will go on over top, but need to be set between the teeth.
