1. A wheel chock handling unit for use with a wheel chock, the wheel chock handling unit including:
a base;
an articulated cantilever arm assembly having opposite first and second ends, the first end being pivotally mounted to the base for angular displacement of the arm assembly in a substantially vertical plane between a storage position and an extended position, the arm assembly comprising:
a proximal arm; and
a distal arm;
the proximal arm having opposite top and bottom ends and the distal arm having opposite top and bottom ends, the first end of the arm assembly corresponding to the bottom end of the proximal arm and the second end of the arm assembly corresponding to the bottom end of the distal arm;
the proximal and distal arms being pivotally connected for pivoting the distal arm about a pivot axis perpendicular to the vertical plane;
a pivoting assembly laterally offset from the pivot axis of the arm assembly comprising:
a first member secured to the distal arm, having a first member top end and a bottom end and a longitudinal axis extending therebetween; and
a second member secured to the first member at a first position that is offset from the first member top end along the longitudinal axis, and configured to be pivotally connected to the proximal arm;
a main spring assembly extending between the arm assembly and the base, comprising:
a rigid structural connector member connected to the pivoting assembly at a position above the first position, the connector member having a portion extending towards the base; and
at least one spring having:
a top end operatively connected to the portion of the connector member extending towards the base; and
a bottom end operatively connected to the base.
