lifting hook question

[Russ Hanscom]

The obvious answer is that there are no specs, if it can be loaded on the boat without failing then it is good to go.

I have a neighbor who has a side business working on "big wheel trucks", off-the-road trucks, and similar. He has a legit 2T engine hoist. It looks like it could lift any of my tractors.

I'm sure they run an analysis in Autocad and it tells them they have a 1.2 safety factor assuming a vertical static load.

As far as I know, they still proof test All lifting devices at 2:1. That’s an actual physical test, to check for any material yielding.

I am doubtful HF got that memo! I would honestly call John's guess at a 1.2 safety factor optimistic. Legit lifting companies, sure. But not these engine hoists. I think the only thing they really go off of is the ram's capacity and the leverage on the boom.

No argument with that Dave. The Horror Freight hoists are reverse engineered, like most everything else they do. I’d guess they physically copied the hook, as well as the rest of the hoist, and called it a party.

Exactly my thoughts.
