ABSTRACT:
A crane assembly has a bracket, a supporting plate, a crane device, a chain and a chain bag. The bracket has two side plates with wheels connected with each other. Each side plate has a first recess defined in the bottom of the side plate to make the side plate have an inverse U-shape. Two axles are mounted between the side plates and are respectively located at two sides of the first recesses in the side plates to combine the side plates together. The supporting plate is attached to the axles and is mounted between the side plates. The craning device is pivotally attached to the supporting plate and has a top portion received in the first recesses in the side plates. Accordingly, the location of the crane device is heightened, and the craning travel of the chain is prolonged.
