A barrel dolly (10) includes a main frame (12) that has members (16, 18, 20, 22) for supporting a barrel (42) and a roller frame (14) detachable from the main frame for loading the barrel through an open end (22) of the main frame. The main frame includes bridge hooks (30) that mate with receiver notches (34) on the roller frame for attaching the roller frame to the main frame. The roller frame includes a sliding handle (38) that a user grasps to rotate the roller frame for releasing and securing the roller frame and the main frame. An optional lifting handle (54) enables the user to safely and easily load heavy barrels on the barrel dolly.

1. A dolly apparatus for loading and transporting a container on a surface, comprising:a generally U-shaped main frame having a back support member supported by a first wheel set and mechanically coupled to opposed side members that form an open end of the main frame through which the container can be loaded; a pair of bridge hooks attached to the opposed side members and protruding from the open end of the main frame; and an elongated roller frame having opposed ends supported by a second wheel set, the opposed ends including receiver notches that are aligned to receive the bridge hooks protruding from the main frame, the roller frame being rotatable from a bridge hook receiving angle to a final angle and further including a first fulcrum point that contacts the surface when the roller frame is at the bridge hook receiving angle, a second fulcrum point that contacts the surface when the roller frame is at an intermediate angle between the bridge hook receiving angle and the final angle, and a third fulcrum point that contacts the surface when the roller frame is between the intermediate angle and the final angle, for providing stable attachment of the roller frame to the main frame and thereby support by the first and second wheel sets of the dolly apparatus and any container loaded thereon. 2. The apparatus of claim 1, further including a bottom support member attached between the opposed side members and adjacent to the open end of the main frame.3. The apparatus of claim 1, in which the roller frame has captivated thereto a sliding handle for rotating the roller frame from the bridge hook receiving angle to the final angle.4. The apparatus of claim 3, in which the main frame further includes a stowing bracket for receiving an end of the sliding handle when the roller frame is attached to main frame to lock the roller frame at the final angle.5. The apparatus of claim 1, in which at least one of the first and second wheel sets includes swiveling caster wheels.6. The apparatus of claim 1, in which at least one of the first and second wheel sets includes two wheels.7. The apparatus of claim 1, in which the roller frame further includes at least one arcuate member that serves as a fulcrum while the roller frame is rotated between the bridge hook receiving angle and the final angle.8. The apparatus of claim 1, further including a lifting handle and a storage bracket attached to the main frame for storing the lifting handle, the lifting handle usable for tilting the container to ease its loading on the main frame.9. The apparatus of claim 1, in which the container is a 55 gallon drum.10. A method of loading and transporting a container on a surface, comprising:providing a generally U-shaped main frame having an open end that contacts the surface, a closed back end supported above the surface by a first wheel set, and bridge hooks that protrude from the open end; tilting the container and sliding the open end of the main frame under the container such that the main frame supports the container providing a roller frame supported by a second wheel set and including receiver notches that are spaced apart to receive the bridge hooks protruding from the main frame, the roller frame further including a first fulcrum point that contacts the surface when the roller frame is at a bridge hook receiving angle, a second fulcrum point that contacts the surface when the roller frame is at an intermediate angle between the bridge hook receiving angle and a final angle, and a third fulcrum point that contacts the surface when the roller frame is between the intermediate angle and the final angle; rotating the roller frame to the bridge hook receiving angle such that the receiver notches engage the bridge hooks; rotating the roller frame through the intermediate angle such that the receiver notches lift the bridge hooks and thereby the open end of the main frame and the container off the surface; and rotating the roller frame to the final angle such that the roller frame and the main frame are attached and support the container for transporting above the surface by the first and second wheel sets. 11. The method of claim 10, in which the rotating is carried out by a handle attached to the roller frame.12. The method of claim 11, further including locking the roller frame to the main frame by securing the handle to the main frame when the roller frame is at the final angle.13. The method of claim 10, further including providing a lifting handle for tilting the container.14. The method of claim 13, further including storing the lifting handle on the main frame.15. The method of claim 11, in which at least one of the first and second wheel sets includes two wheels.16. The method of claim 11, in which at least one of the first and second wheel sets includes a swiveling caster wheel.
