Omni Block Failure

There is no doubt that gear should be inspected frequently, however, in my opinion, it seems that the bigger issue here is that RE was using a set screw as opposed to drilling and pinning the axle assembly. This, in itself would have completely alleviated any potential issues. In my mind, this is a huge red flag for this product. I understand that the set screw was put in place to make the unit rebuildable, but in this case, a set screw is the wrong way to go. It just goes to show you that even a big player like RE has flaws. This is a major issue. A set screw in a product like this is just asking for problems.
 
Maybe they've done away with the set screw. I recently got a 1.5" and a 2.6" material handler and they got little coiled spring pins in them. It looks like after the pin is in, they deform the hole to lock it in place.

Are both of the holes on them deformed? I get what your implying with the deformation but they are supposed to stay in without. I wonder if it's just an assembler using the wrong punch to set it. Seems odd they will purposely deform a precise product like that.

What is the difference anyways between the MHP & the other (sorry I don't remember the nomenclature)?

Both my 1.5" and MHP2.6 are like that. Like they used a bit and a press to deform the hole. I imagine it's to keep the pin in place and to keep the consumer from messing with it at all. The idea is if you find any play or vertical movement in the swivel, you send the pulley to Rock Exotica instead of tightening it yourself. It looks like the pin isn't going anywhere without drilling the outside of that hole that's now oblong/ deformed.

I don't have a regular 2.6 omni to compare the 2, but from what I gather, the difference is the material handler is rated in pounds force instead of kilo newtons, it's red instead of orange, and it's certified to meet ASTM standards for lifting and industrial rigging. So far that's the only difference I can tell, but there may be more.

You know what? I just remembered I actually asked rock-o all this before.. i just searched my emails.. here is their response to questions about shock loading either of those two pulley models & asking what the difference is..

I'm actually hesitant to post this quote, as the consensus around here is to not shock load or negative rig/block down on these pulleys.. Anyhow.. here it is..

"Gotchya. You can negative rig with our blocks, just use caution and inspect your gear before and after each set up . The MHP's are the same as the Omni's, just labelled for overhead rigging and marked with pounds-force and colored red.

The larger 4.5 MHP is the largest block we produce will handle shock loads better than the 2.6 MHP/Omni because its bigger."
 
Interesting.
The 2.6 can probably take everything I'd throw at it with a 1/2" rope, but I tend to keep stuff small and not approach limits. Careful to a fault maybe.
