Abstract
A screw jack system with three (or more) stops that is capable of raising and lowering a substantially heavy load. Specifically, once the elevator sleeve travels through the case sleeve and is raised to its maximum height, the three (or more) inner stops of the elevator sleeve engage with the three (or more) outer stop channels of the case sleeve. These engagements are the stopping points of the screw jack which are the optimal points of support in order to prevent any lean from raising or lowering a heavy load or preventing any potential breaking points or sleeve pullout. Further, the screw jack system includes a pinion gear, drive gear, drive screw, elevator screw, and elevator tube that permit a user to covert rotational motion into linear motion in order to perform its desired raising and lowering functions.
