Description
- Often large cargo, such as an appliance, needs to be moved for repair, removal or installation. This type of large cargo is often difficult to move on a typical dolly. In this regard, a typical dolly has a tall frame with a handle on the top of the frame. Coupled to the bottom of the frame is a nose plate. A typical nose plate does not extend in width or length enough to fully go under the appliance for moving. This makes it difficult to move the appliance.
- The system is described with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements. Additionally, the left-most digit(s) of a reference number identifies the drawing in which the reference number first appears.

The exemplary dolly comprises a frame having a first central tube that has a first circumference. The first central tube is hollow. Attached to one end of the first central tube is an angled tube that extends at an angle vertically. At the top of the angled tube is a handle coupled perpendicular to the angled tube. Coupled at the opposing end of the first central tube is a second central tube. In this regard, an end portion of the first central tube has a circumference that is less than the circumference of the second central tube such that the end of the first central tube fits within the second central tube. Note that when not in use, the first and second central tubes may be decoupled for storage.
- Perpendicular to the second central tube is a cross tube. The cross tube may be integral with or coupled to the second central tube. The cross tube is hollow. At one end of the cross tube is a first moveable tube having a circumference that is less than the circumference of the cross tube such that the first moveable tube fits within the cross tube. At the other end of the cross tube is a second movable tube having a circumference that is less than the circumference of the cross tube such that the second moveable tube fits within the cross tube. On non-insertions ends, each moveable tube is fixedly coupled to a stop and an axle, and a wheel is rotatably coupled to each axle. Thus, when the moveable tubes are adjusted, the stops, the axles, and the wheels are automatically adjusted accordingly.
- In use, large cargo rests on the central tubes and the cross tube. Further, the moveable tubes are configured to move inward or outward relative to the cross tube so that different sizes of cargo may be secured horizontally to the dolly via the stops.
