Claims

[Scope of claim for utility model registration] 1. In a grounding collector for a crane that enables the crane saddle and the traveling rail to be mutually energized:
A brush stand 1 on which a brush 2 whose tip is brought into contact with a travel rail 15 is installed, a support 4 erected from the brush stand 1, and a support 4 attached to the crane saddle 13 to slidably support the support 4. It consists of a fixture 9, and resilient means 16 and 17 that are interposed between the fixture 9 and the brush stand 1 and urge the brush base 1 toward the traveling rail 15; the fixture 9, the support column 4, A grounding current collector for a crane, characterized in that the triggering means 16, 17, the brush stand 1, and the brush 2 are made of a conductive material. 2 The resilient means constitutes a first spring 16 and a second spring 17; the first spring 16 is interposed between the fixture 9 and the brush stand 1, and the brush stand 1
while biasing the second spring 17 toward the support column 4 inserted from the fixture 9.
The spring pressure of the first spring 16 is applied to the spring pressure of the second spring 17. A grounding collector for a crane according to claim 1, characterized in that the earthing collector is larger than the pressure.
