Method for freight container loading
Disclosed are apparatuses and methods for use thereof for loading bulk material into freight containers. One apparatus comprises a hopper configured to receive bulk material that is sized and shaped to be at least partially enclosable by a container to occupy a substantial volume of the container and a ram. The ram comprises a plate and a driver configured to move the plate from a back end of the hopper to an open end of the hopper to expel material into a container. Another apparatus comprises a hopper configured to receive bulk material that is sized and shaped to be at least partially enclosable by a container to occupy a substantial volume of the container and a reciprocating conveyor floor system. Optionally, a chute can be employed in combination with a loader vehicle to quickly and efficiently load bulk material into a container.
1. A method of loading bulk material into a shipping container, comprising:
(a) providing a channel having a proximal section with an open proximal end and a distal section having a distal end;
(b) backing the shipping container into a position such that the container encloses the distal section of the channel, and such that the distal end of the channel substantially extends to a front wall of the container, whereby the channel takes up substantially the entire length of the container and ends up just short of the front wall of the container;
(c) advancing a self-propelled loader vehicle through the open proximal end into the proximal section of the channel;
(d) depositing a quantity of bulk material into the proximal section of the channel; and
(e) causing the loader vehicle to push the deposited bulk material along the channel into said container and off the distal end of the channel.
2. The method of claim 1 , wherein the step of depositing a quantity of bulk material into the proximal section of the channel, and the step of causing the loader vehicle to push the deposited bulk material along the channel into the container and off the distal end of the channel, are repeated until the container is full.
3. The method of claim 2 , wherein each quantity of bulk material that is deposited in the channel prior to being pushed into the container comprises substantially less than the bulk material capacity of the container.
4. The method of claim 1 , wherein the container is shifted forwardly as bulk material is pushed off the distal end of the channel.
5. The method of claim 1 , wherein the container is shifted forwardly after bulk material is pushed off the distal end of the channel.
6. The method of claim 1 , wherein the container is shifted forwardly by the loader vehicle as it pushes bulk material off the distal end of the channel.
7. A method of loading bulk material into a shipping container with a channel, wherein the shipping container has a front wall and the channel has a proximal section with an open proximal end and a distal section having a distal end, the method comprising:
enclosing the distal section of the channel with the shipping container such that the distal end of the channel substantially extends to and short of the front wall of the container;
advancing a self-propelled loader vehicle through the open proximal end into the proximal section of the channel;
depositing a quantity of bulk material into the proximal section of the channel; and
causing the loader vehicle to move the deposited bulk material along the channel, into the container and off the distal end of the channel.
8. The method of claim 7 wherein the step of depositing a quantity of bulk material and the step of moving the deposited bulk material are repeated until the container is full.
9. The method of claim 8 wherein each quantity of bulk material that is deposited in the channel prior to being moved into the container comprises substantially less than the bulk material capacity of the container.
10. The method of claim 7 wherein the container is shifted forwardly as bulk material moves off the distal end of the channel.
11. The method of claim 7 wherein the container is shifted forwardly after bulk material moves off the distal end of the channel.
12. The method of claim 7 wherein the container is shifted forwardly by a loader vehicle as the loader vehicle pushes bulk material off the distal end of the channel.
