Transportation container

1. A container for transporting material comprising:

a main body comprising a floor, two sidewalls, and an end wall, wherein the sidewalls and the end wall define a perimeter that at least partially defines an interior space; and

a liner disposed within the interior space of the main body, the liner comprising a floor, two sides, and an end panel, wherein the sides and the end panel define a perimeter with a shape corresponding to a shape of the perimeter of the main body and at least partially define an interior space,

wherein the floor of the main body and the floor of the liner have substantially the same shape, but differ in size such that a gap is provided at least between the two sidewalls of the main body and the two sides of the liner, and

an uppermost perimeter of the liner is movably connected to an uppermost perimeter of the main body to allow the two sides and the bottom of the liner to thermally expand into the gap.

2. The container of claim 1 , wherein the main body is comprised of a plurality of frame members that define a plurality of open spaces.

3. The container of claim 1 , wherein the liner is movably connected to the main body by at least one pin attached to the main body or the liner that extends through at least one elongated slot in the other of the main body or the liner.

4. The container of claim 1 , wherein a lift gate is pivotably attached to the main body.

5. The container of claim 1 , further comprising:

a lift gate pivotably attached at an open end of the main body; and

a link having a first end connected to the lift gate and a second end adapted to be connected to a vehicle used to transport the container,

wherein when the container is placed on the vehicle and a closed end of the main body is raised with respect to the open end of the main body, the engagement of the link with the lift gate and the vehicle automatically transitions the lift gate from a first position in which the open end of the main body is covered by the lift gate to contain material within the interior space to a second position in which the open end of the main body is not covered by the lift gate to allow material to be emptied from the interior space.

6. The container of claim 5 , wherein the link is a flexible attachment member comprised of a cable.

7. The container of claim 6 , wherein the cable is threaded through a plurality of pulleys between the first end and the second end to facilitate transitioning of the lift gate.

8. The container of claim 1 , wherein a flange extends from the sides and the end panel of the liner at an uppermost perimeter of the liner and the flange is movably connected to an upper surface of the sidewalls and end wall of the main body.

9. The container of claim 1 , further comprising a plurality of rollers located on the underside of the floor of the main body.

10. The container of claim 1 , further comprising a plurality of nose rollers located between two rails on an underside of the floor of the main body to assist in loading the container onto a transportation vehicle.

11. An assembly for transporting material comprising:

the container of claim 5 ; and

a vehicle including an engagement member that connects to the second end of the link.

12. The assembly of claim 11 , wherein the link is a flexible attachment member comprised of a cable.

13. The assembly of claim 12 , wherein the cable is threaded through a plurality of pulleys between the first end and the second end to facilitate transitioning of the lift gate.

14. The assembly of claim 11 , wherein the container is removable from the vehicle.
