A transportable jack system includes a jack disposed on a base. The base includes a base plate with a plurality of wheel openings formed therein, and a biasing member disposed between a wheel and the base plate. The biasing member is configured from a single piece of material consisting of a top horizontal portion, a bottom horizontal portion, and an angled middle portion disposed between the top horizontal portion and the bottom horizontal portion. The biasing member biases the base away from a ground surface when a load applied to the jack is below a predetermined threshold and deforms when the load is above the predetermined threshold, wherein the deformation allows the base plate to contact the ground surface.
