A floodlight is installed on the bottom surface of the floodlight base, and a junction box is installed on the top surface of the junction box base. The floodlight is connected to the first support plate by a fall-proof chain.

[0006] As a further improvement to the above technical solution:

[0007] Optionally, a handle is fixed to the top of the lifting extension rod.

[0008] In a detachable floodlight device for a port crane provided by this utility model, a first support plate and a second support plate are fixed to the side of the crane body, and a lifting extension rod is provided. One end of both the first and second support plates has a mounting hole, and the top surface of each has an anchoring hole. The lifting extension rod is located in the two mounting holes, and two steel plates are fixed to its side. The two steel plates are respectively located on the top surface of the first and second support plates, and their bottom surfaces are fixed with anchors located in the anchoring holes. A floodlight base and a junction box base are installed on the bottom side of the lifting extension rod. A floodlight is installed on the bottom surface of the floodlight base, and a junction box is installed on the top surface of the junction box base. The floodlight is connected to the first support plate via a fall arrestor chain. Using this detachable floodlight device for a port crane is convenient to maintain, has low safety risks, strong wind resistance, and is beneficial to improving port operation efficiency.
