They are BAL 23007 jacks. They are rated for 1000 lbs, but they can't lift anywhere near that, and the plane the screw and leg lie in must be perfectly vertical. This means they can't carry that load unless the trailer is perfectly level.
They are stabilizers--not really jacks in the true sense and should not be used for lifting purposes. The design does not allow for much leverage without excessive force.
They can be used to make some very fine level adjustments if needed.
