weight limits on 2x10 floor joist

Can you set the equipment so it is over the supports of the floor so the floor is actually carrying little weight? Is this a static weight or does the machine present a dynamic load due to moving parts and vibrations?

Proper cross bracing will spread the weight on adjacent joists. If you have concerns, why not double up the joists under the equipment.

You could always put a beam across the two joists and a pole to the floor. That would ease your mind.

Try here.

You need a lot more detail than that to determine if it's safe.

First off, 30" x 26" (5.4 sq. ft.) is not a large area, so it would be considered a point load.

Now, what is "very heavy"? Some people would consider 500# very heavy, though it's equal to a couple large people standing together. 2,000# would reasonably be considered very heavy.

Next, what other loads are on this section of floor? Is the underside accessible for providing additional support? Is there height available for a load spreading structure between the equipment and the floor? How about dynamic load like someone else mentioned? Big difference between a welder and a punch press as far as dynamic loading.
