Description

technical field

[0001] The invention relates to a large mining excavator, in particular to a cable drum device for the large mining excavator and a large mining excavator with the cable drum device. Background technique

[0002] With the gradual mining of large-scale open-pit mines, the demand for large-scale mining excavators is gradually increasing. At the same time, users have put forward higher requirements for the performance and human-machine safety of excavators.

[0003] In the past, in order to reduce the purchase cost, the user did not have a cable reel device at the tail of the large mining excavator, but made a cable bracket in the shape of a sledge. When the excavator was working on site, the external cables were fixed on the cable bracket. 6kV Or the 10kV external cable is dragged on site, the cable wear is serious and the risk is high.

[0004] Considering the above problems, a cable reel device has been installed at the tail of large mining excavators to imp...
