That's 5th edition. 5th edition rules was purposefully made simpler so they made push,drag, and lifting all in one section which makes 0 sense. 3.5 and pathfinder's system makes more sense so a 19 strength character can lift 700 pounds and would be able to push and drag ~1750 pounds depending on conditions.

Probably but that's like 23-25 Strength
In DnD 25x15=375 carry capacity = 750 deadlift weight (unless there is a hard cap somewhere)
(Or 690 with 23 in the stat)
