Abstract: A lifting device for lifting heavier loads is disclosed including a square base plate having a plurality of wheels attached in triangular arrangement which provide a low center of gravity for the lifting device. Mounted in the center of the square base plate is a cylindrical housing having a sealed tube within an unsealed tube, a space between the tubes, a fluid holding chamber, a fluid filed chamber, a fluid filled space, a plurality of hydraulic seals, an orifice between the fluid filled space and the fluid holding chamber, a plurality of orifices in the bottom aspect of the fluid holding chamber and a plurality of external connections, an orifice in the top aspect of the fluid holding chamber between the fluid holding chamber and the operating chamber, a tube in the fluid holding chamber for transferring pressurized hydraulic fluid to the operating chamber, and a piston assembly having an operating chamber which is slidable longitudinally in the cylindrical housing.
