Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] This disclosure is further described in the detailed description that follows, with reference to the drawings, in which:

[0015] FIG. 1 illustrates, in simplified form, a schematic view of one example cargo container lift truck as described herein; and

[0016] FIG. 2 illustrates, in simplified form, a schematic view of the cargo container lift truck of FIG. 1 from a different direction.

DETAILED DESCRIPTION

[0017] Specific examples of our cargo container lift truck will now be described with reference to the accompanying drawings. It should be apparent that the described examples are only representative of a few, not all, of the embodiments that can be created based upon this disclosure. All other embodiments that can be created by those skilled in the art based on the examples herein are intended to be encompassed by the present disclosure.

[0018] Referring to FIG. 1 and FIG. 2, the cargo container lift truck comprises a body 1. The body 1 includes drive wheels 11 and at least one turning wheel 12 at the bottom. The body 1 also includes a lift nose 2 that capable of going up and down along the body 1. More specifically, the lift nose 2 comprises a lift body 21 that goes up and down along the body and fork levers 22 located on the two sides of the front of the lift body 21. The bottom of the fork levers 22 includes support rods 23 for holding up a cargo container 6. The body 1 further includes a movement drive device 3 that rotationally drives the drive wheels 11 and a lift drive device 4 that drives the lift nose 2 up and down. The body 1 further includes a pivotable handle 5 to control the body. The handle 5 includes buttons 16, 18, one 16 that controls forward and backward movement of the body and another 18 that controls raising and lowering of the lift nose. During use, the lift nose 2 is initially in its lowest position so that it can go underneath a cargo container 6. Then the lift nose 2 is raised and the lift truck and cargo container 6 are moved to a new location. The lift nose 2 is then lowered at the new location, yielding a use that is simple, convenient, and efficient.

[0019] The movement drive device 3 comprises a drive motor 31, a speed reducer 32, sprockets 7 and chains 8. The drive motor 31 is connected to, and drives, the speed reducer 32. The speed reducer 32 and the drive wheels 11 each include the sprockets 7, and the sprockets are connected to each other via the chains 8 so that the drive wheels 11 can be driven.

[0020] Ideally, the lift drive device 4 is a hydraulic oil cylinder, which directly controls the raising and lowering of the lift nose. Alternatively, the lift drive device 4 is a lift motor 41 and a lift rod 42 that is driven by the lift motor 41. The lift motor 41 controls the raising and lowering of the lift rod 42 to control raising and lowering of the lift nose 2.

[0021] In addition, the body 1 comprises a vertical support 13 and a base 14, the support 13 is fixed onto, or part of, the base 14, and the base 14 is provided with a U-shaped support groove.

[0022] Ideally, there are two drive wheels 11 and one or two turning wheels 12, with the drive wheels 11 and the turning wheels 12 being positioned in a triangle configuration (if only one turning wheel 12) or a quadrilateral configurations (e.g., square) (if two turning wheels 12).

[0023] Ideally, the turning wheels 12 are universal casters.

[0024] The handle 5 also includes a speed regulation button 9. The speed regulation button is used to regulate the speed at which the body 1 moves forward and backward.

[0025] Having described and illustrated the principles of this application by reference to one or more example embodiments, it should be apparent that the embodiment(s) may be modified in arrangement and detail without departing from the principles disclosed herein and that it is intended that the application be construed as including all such modifications and variations insofar as they come within the spirit and scope of the subject matter disclosed.
