a base;
a lower frame connected to the base;
a plurality of wheels supporting the lower frame and the base;
an upper frame pivotably secured to the lower frame, the upper frame configured to support a pallet thereon;
a gear coupled to the upper frame, such that rotation of the gear in a first direction lifts the upper frame relative to the lower frame;
a pawl engaging the gear to prevent rotation of the gear in a second direction opposite the first direction;
a spring biasing the pawl against the gear;
an outer plate configured to reposition the spring such that the spring would bias the pawl away from the gear; and
a handle configured to rotate the gear in the first direction.
