Westinghouse machine weights

Hello,
Does anyone have literature on Westinghouse geared elevator machine weights?

Specifically machine numbers: 28, 38, and 58

We are replacing the machines on a mod and have to calculate the forces on the machine beams compared to the old machines. I know Otis had a little handbook with info like this, and was wondering if Westinghouse may have as well. If not, no big deal, I can just weigh the machines with a dynamometer.

Thanks

In the past Sheila has helped me.
