Composite cribbing
An improved cribbing apparatus for placement at selected locations at a site of an accident to stabilize a post-accident vehicle against unwanted shifting on ground located at the accident site during rescue of a victim trapped in the vehicle, the cribbing apparatus includes a composite cribbing having a wedge shape with a forward end, a rearward end spaced longitudinally from the forward end, an upper surface, and a lower surface spaced altitudinally from the upper surface, wherein the composite cribbing includes a core of plastic or a substantially non-compliant material, and a skin of wood, rubber, or a substantially compliant material on the upper and/or lower surfaces thereof.
1 . A cribbing apparatus for placement at selected locations at a site of an accident to stabilize a post-accident vehicle against unwanted shifting on ground located at the accident site during rescue of a victim trapped in the vehicle, the cribbing apparatus comprising:
a composite cribbing having a wedge shape with a forward end, a rearward end spaced longitudinally from the forward end, an upper surface, and a lower surface spaced altitudinally from the upper surface;
wherein said composite cribbing comprises a core of plastic or a substantially non-compliant material, and a skin of wood, rubber, or a substantially compliant material on the upper and/or lower surfaces thereof.
2 . The cribbing apparatus of claim 1 , wherein said skin is affixed to said upper and lower surfaces.
3 . The cribbing apparatus of claim 1 , wherein said skin is affixed to said core using glue, epoxy or cement.
4 . The cribbing apparatus of claim 1 , wherein said skin is reversibly affixed to said core.
5 . The cribbing apparatus of claim 1 , wherein said skin spans said core from said forward end to said rearward end.
6 . The cribbing apparatus of claim 5 , wherein said skin does not hang over the edge of the core.
7 . The cribbing apparatus of claim 1 , wherein the wedge is a single rigid unit including a plastic core with wood skins rigidly affixed to the upper and lower surfaces thereof.
