Ramp structure

A ramp structure, the ramp structure comprising:

• a first ramp kerb;
• a second ramp;
• each of the first and the second ramp kerbs comprising a first longitudinally extending channel open at an inner transverse edge of the ramp kerb and a second longitudinally extending channel open at the inner transverse edge of the ramp kerb, wherein said first and second longitudinally extending channels are vertically spaced;
• a ramp surface having transverse edges spaced by an uppermost lateral edge and a lowermost lateral edge, a first of the transverse edges of the ramp surface being received in the first longitudinally extending channel of the first ramp kerb, and a second of the transverse edges of the ramp surface being received in the first longitudinally extending channel of the second ramp kerb;
• first and second ramp lip extensions, each of the first and second ramp lip extensions comprising a lip surface having transverse edges spaced by an uppermost lateral end and a lowermost lateral end, and an attachment portion comprising a downwardly depending skirt depending from the uppermost lateral end of the lip surface and at least one projection projecting from said skirt away from said lip surface, wherein said at least one projection is vertically spaced below said uppermost lateral end of the lip surface by said skirt;
• wherein the at least one projection of the first ramp lip extension is received in the second longitudinally extending channels of the first and second ramp kerbs, such that the uppermost lateral end of the lip surface of the first ramp lip extension is in abutment with the lowermost lateral end of the ramp surface;
• and
• wherein the at least one projection of the second ramp lip extension is received in the second longitudinally extending channels of the first and second ramp kerbs, such that the uppermost lateral end of the lip surface of the second ramp lip extension is in abutment with the uppermost lateral end of the ramp surface.
