Abstract

An apparatus for lifting a buried explosive device includes a T-shaped base including a flange member and a web member. The web member has one end fixed at a right angle to the midpoint of the flange member. A vertical upright member is fixed at one end to the midpoint of the flange member. A diagonal member is fixed at one end to the other end of the vertical upright member and fixed at another end to a second end of the web member that is distal the flange member. The vertical upright member is at least twice a length of the web member. The flange member, the web member, the vertical upright member and the diagonal member are L-channel members made of carbon fiber.

First claim

What is claimed is:

1. An apparatus for lifting a buried explosive device, comprising:
a T-shaped base including a flange member and a web member, the web member includes one end fixed at a right angle to a midpoint of the flange member to form the T-shaped base;
a vertical upright member being fixed at one end to the midpoint of the flange member and normal to the plane of the T-shaped base, the vertical upright member includes a second end that is distal the T-shaped base;
a diagonal member being fixed at one end to the second end of the vertical upright member and being fixed at another end to a second end of the web member that is distal the flange member;
wherein the vertical upright member is at least twice a length of the web member, and wherein the flange member, the web member, the vertical upright member and the diagonal member are L-shaped channel members; and
a first brace being fixed at one end to a lower half of the vertical upright member and being fixed at another end to one side of the flange member,
wherein the first brace extends at an angle from the vertical upright member to the one side of the flange member.

2. The apparatus for lifting a buried explosive device of claim 1 , further comprising a second brace being fixed at one end to an opposite side of the flange member from the first brace and being fixed at another end to the web member, the second brace extends at an angle from the flange member to the web member.

3. The apparatus of claim 2 , wherein the vertical upright member and the diagonal member each comprise a plurality of sub-members fixed together.

4. The apparatus for lifting a buried explosive device of claim 1 , further comprising a pull line including one end being fixed at an intersection of the second end of the vertical upright member and the diagonal member and another end located distal from the vertical upright member.

5. The apparatus for lifting a buried explosive device of claim 4 , further comprising a connector being configured for connecting to the buried explosive device, the connector is fixed at an intersection of the second end of the web member and the diagonal member.

6. The apparatus of claim 1 , wherein said each of the L shaped-channel members comprises a pair of equal width legs normal to each other.

7. An apparatus for lifting a buried explosive device, comprising:
a T-shaped base including a flange member and a web member, the web member includes one end fixed at a right angle to a midpoint of the flange member to form the T-shaped base;
a vertical upright member being fixed at one end to the midpoint of the flange member and normal to the plane of the T-shaped base, the vertical upright member includes a second end that is distal the T-shaped base;
a diagonal member being fixed at one end to the second end of the vertical upright member and being fixed at another end to a second end of the web member that is distal the flange member;
wherein the vertical upright member is at least twice a length of the web member, and wherein the flange member, the web member, the vertical upright member and the diagonal member are L-shaped channel members;

a pull line including one end being fixed at an intersection of the second end of the vertical upright member and the diagonal member and another end located distal from the vertical upright member; and
a connector being configured for connecting to the buried explosive device, the connector is fixed at an intersection of the second end of the web member and the diagonal member,
wherein, with the buried explosive device fixed to the connector and disposed below a ground level, a pull force on the pull line causes the apparatus to rotate and lifts the explosive device up to ground level without mechanical failure of the apparatus, when a force at the connector is up to about 400 pounds.

8. An apparatus for lifting a buried explosive device, comprising:
a lever in the form of a truss, the truss having a base configured to rest on a ground, one end of the base acting as a fulcrum for the lever and another end of the base configured for attachment to the buried explosive device, the truss including a vertical upright member fixed normal to the base at the one end of the base and a diagonal member extending from the other end of the base to a top of the vertical upright member wherein the truss is made of a plurality of L channel members comprising carbon fiber.

9. The apparatus for lifting a buried explosive device of claim 8 , wherein the truss is operable to withstand a force of up to about 400 pounds, measured at the end of the base configured for attachment to the buried explosive device.

10. The apparatus for lifting a buried explosive device of claim 8 , wherein the base is a T-shaped base, which includes a flange member and a web member, and wherein the web member includes one end fixed at a right angle to a midpoint of the flange member to form the T-shaped base.

11. The apparatus for lifting a buried explosive device of claim 8 , wherein the base is a T-shaped base, which includes a flange member and a web member, wherein the web member includes one end fixed at a right angle to a midpoint of the flange member to form the T-shaped base, and wherein the vertical upright member is fixed at one end to the midpoint of the flange member and the diagonal member is fixed at one end to the top of the vertical upright member and fixed at another end to a second end of the web member that is distal the flange member.

12. The apparatus for lifting a buried explosive device of claim 11 , wherein the vertical upright member is at least twice a length of the web member.

13. The apparatus for lifting a buried explosive device of claim 8 , wherein each of the plurality of L-channel members comprises a pair of equal width legs normal to each other.
