Description

Technical Field:

[0001] The utility model relates to the technical field of crane booms, and more specifically to a crane provided with a lighting device. Background Art:

[0002] The jib crane, also called the slewing jib crane, simply referred to as the slewing jib, is a medium and small-sized lifting equipment developed in recent years. It has a unique structure, is safe and reliable, and has the characteristics of high efficiency, energy saving, time and labor saving, and flexibility. It can be operated arbitrarily in three-dimensional space. In the occasions of short-distance and intensive lifting, it shows more superiority than other conventional lifting equipment. At present, an I-beam steel structure guide rail is provided on the lower side of the cantilever of the slewing jib. Its electric hoist is arranged on the guide rail of the cantilever and can move on the cantilever. However, it limits the installation of lighting fixtures on the cantilever. Otherwise, the electric hoist will interfere with the lighting fixtures during the moving process. However, if no lighting fixtures are installed on the cantilever, the use is limited in the dark environment range. Therefore, a crane cantilever structure in which the electric hoist does not affect the lighting fixtures needs to be designed. Content of the Utility Model:
