Abstract

A material handling system is disclosed, having at least one solid rectangular storage container for liquid or solid items; a pallet upon which the container sits; and a transporter which is adapted to move the container from the pallet. The pallet has a structure to permit both movement of the pallet and the container and movement of the container independent of the pallet. The transporter with the container can be moved safely and easily using human power.

Claims

1. A material handling system, comprising:

(a) at least one solid rectangular storage container for liquid or solid items;

(b) a pallet upon which the container sits; and

(c) a transporter which is adapted to move the container from the pallet;

wherein the pallet has a structure to permit both movement of the pallet and the container and lifting of the container from the pallet and movement independent of the pallet;

wherein the pallet has an upper surface and a series of ribs rising above the upper surface;

wherein the ribs comprise a center rib, two edge ribs, and two support ribs combining to provide a container support surface;

wherein the ribs extend nearly an entire distance of the upper surface from the front of the pallet to the back of the pallet;

wherein the transporter has a platform with a split forming two toe plates and a gap between the toe plates that is slightly wider than the width of the support ribs;

wherein the transporter has two larger wheels for vertical alignment of the container on the transporter and two smaller wheels to be used with the larger wheels for alignment of the container on the transporter at an angle to a floor;

wherein the transporter has a frame of tubes and wherein the frame rotates about an axis of junction between the tubes and the platform to alter the position of the platform from parallel to a floor to angled to the floor with the container reclining at about a 30°

angle relative to the floor;

wherein the transporter has a double, reversing curvature frame from the tubes to the two smaller wheels, wherein the double, reversing, curvature of the frame from the tubes to the smaller wheels provides a center of gravity in all situations which has the principal mass of a filled container over a plane between the larger wheels and the smaller wheels;

wherein the transporter has a dual handle assembly, wherein one handle is for maneuver of the transporter when upright relative to the floor and a second handle for maneuver of the transporter when reclining at an angle relative to the floor;

wherein the platform of the transporter has at least two positions, comprising regular flush position with a floor and elevated position for use with the pallet wherein the platform has tubular ends of an inside diameter slightly larger than diameter of tubes of the frame, wherein each end has a hole bored in the same axis as the axle of the transporter, whereby aligning holes on the tubular ends and the tubes of the frame permits the platform to be raised from a floor level to a pallet level using mechanical locking pins to firmly secure height of the platform at a useful level relative to the upper surface; and

wherein the container on the transporter can be moved by human power.

2. The system of claim 1, wherein the container support surface ranges from about 1.9 to about 3.81 cm above the upper surface, and wherein the space between upper surface and container support surface is sufficient to permit the transporter to be inserted to lift and move the container from the pallet.

3. The system of claim 1, wherein the upper surface of the pallet is made of a plurality of upper deck boards in alignment with a plurality of lower deck boards, both being connected to stringers transversely arranged between upper deck boards and lower deck boards, which elevate the upper deck boards above the lower deck boards to create a space above a floor and the upper surface.

4. The system of claim 3, wherein the ribs are parallel with the stringers.

5. The system of claim 3, wherein the ribs are perpendicular to the stringers.

6. The system of claim 2, wherein the ribs are segmented to permit the transporter to lift the container from either of two different sides of the pallet.

7. The system of claim 1, wherein the pallet is made from a material selected from the group consisting of metal, wood, plastic, and combinations thereof.

8. The system of claim 1, wherein the transporter also has a securement strap to be used about the outer surfaces of the container.

9. The system of claim 1, wherein the double, reversing curvature frame has a first curvature near the larger wheels of approximately 48°

and a second curvature near the smaller wheels of approximately 122°

.

10. The system of claim 9, wherein the larger wheels are outboard of the toe plates.

11. The system of claim 1, wherein the container is made of a single composition to permit recycling both for re-use for the same purpose and re-constitution into another product of the same composition.
