Abstract
Abstract A platform for the lifting and handling of goods comprising a base frame, a loading frame, both made of a polymeric material, and superimposed on one another, and uprights extending between and connecting the frames. The loading frame is formed by a pair of reticular structures, which are superimposed on one another. The intersecting elongate members of each reticular structure are staggered with respect to those in the other such structure and the reticular structures are connected to form a rigid construction at least by means of joining elements connecting the structures at locations where the elongate members of one structure cross those of the other structure.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
133 words
In a platform for the lifting and handling of goods, comprising a base frame, a frame forming a loading plane, both frames being made of a polymeric material, and being superimposed on one another, and uprights extending between and connecting the frames, the improvement wherein the frame forming the loading plane is formed by a pair of spaced apart superimposed reticular structures which each comprise a network of intersecting elongate members, the members of each reticular structure being staggered with respect to those in the other such structure and the reticular structures being connected at least by means of joining elements connecting the structures at locations where the elongate members of one structure cross those of the other structure forming the loading frame itself as a rigidly braced three dimensional reticular framework structure.
Claim 2
Dependent Claim
133 words
In a platform for the lifting and handling of goods, comprising a base frame, a frame forming a loading plane, both frames being made of a polymeric material, and being superimposed on one another, and uprights extending between and connecting the frames, the improvement wherein the frame forming the loading plane is formed by a pair of spaced apart superimposed reticular structures which each comprise a network of intersecting elongate members, the members of each reticular structure being staggered with respect to those in the other such structure and the reticular structures being connected at least by means of joining elements connecting the structures at locations where the elongate members of one structure cross those of the other structure forming the loading frame itself as a rigidly braced three dimensional reticular framework structure.
Claim 3
Dependent Claim
33 words
A platform according to claim 1 wherein the said reticular structures are formed by series of joists located to form said elongate members having the cross-sectional dimensions of about 8 × 10 cm.
Claim 4
Dependent Claim
55 words
A platform according to claim 1 wherein said joining members are uprights having cross-sectional dimensions corresponding to the breadth of the respective elongate members which they connect so as to lie flush with the side surfaces of the elongate members in order to allow removal of the frame from the mould after its forming therein.
Claim 5
Dependent Claim
30 words
A platform according to claim 1 wherein a web connects adjacent joining elements and closes the space in the superimposed structures, when viewed from above, defined between those joining elements.
Claim 6
Dependent Claim
51 words
A platform according to claim 1 wherein the base frame is formed by a structure comprising a perimetrical rim and a cruciform central stiffening structure both formed of elements comprising a raised central portion having on both sides side walls; said portions and side walls being connected by transversel stiffening ribs.
Claim 7
Dependent Claim
45 words
A platform according to claim 1 wherein the base frame and the frame forming the loading plane are separate mouldings and said uprights comprise upright sections formed around the periphery of the opposed faces of said frames which sections have juxtaposed end surfaces secured together.
