<p>A wheel spacer(10) having a boundary wall (12) being substantially rectangular in shape. The boundary wall (12) is defined by first and second longitudinal walls (20) and first and second latitudinal walls (30). Extending between the longitudinal walls (20) are a plurality of load bearing members (40) having a chamfered top and bottom surface. The load bearing members (40) are spaced in cooperating pairs each providing a space for a row of wheels. Extending between cooperating pairs of load bearing members (40) are load bearing cross-members (50) and extending between non-cooperating pairs of load bearing members (40) are connecting support members (60).</p> |
