Would this work for partial?

As the title says I found this in the base meant not to far off there is a some sort of cement casing and it loose REALLY Heavy would this work??
It's pretty sturdy when I checked the wood and what position would work best? Such as kneeling???

Pull on it and test how strong it is

Exactly: pull on it. If you can bounce on it and it doesn't give, you should be fine. It isn't as if you're going to shock load it for partial.
