Description

Technical Field

[0001] The utility model relates to the technical field of collector installation, in particular to an installation structure of an excavator collector. Background Art

[0002] The collector is the main device for collecting electric energy on the collector side of the busbar system. It conducts electric energy directly to the electrical appliances through the sliding contact between the collector brush and the guide rail, thus realizing the mobile power supply of the system. The collector consists of two parts: a tension device of the mechanical structure and a collector brush that is in direct sliding contact with the guide rail.
