Description

Technical Field

[0001] The utility model relates to the field of auxiliary lighting for excavators, in particular to auxiliary lighting equipment for excavators at night. Background Art

[0002] An excavator, also known as an excavator or a backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the supporting surface and load them into transport vehicles or unload them to a stockpile.

[0003] When an excavator is working at night, lighting equipment is a necessary accessory of the excavator. Relying solely on the excavator's own lighting equipment for lighting cannot meet the lighting needs at all. Therefore, many excavators will install auxiliary lighting equipment on the body to increase the brightness and range of illumination. However, the current auxiliary lighting equipment is directly fixed on the body. When the auxiliary lighting equipment is not in use, it is not convenient to protect the lighting equipment, which can easily cause damage to the auxiliary lighting equipment. Therefore, technical personnel in this field provide an excavator night auxiliary lighting device to solve the problems raised in the above background technology. Utility Model Content
