Patent number: 9349532Abstract: The present invention relates to a turning joint for an electric excavator, which includes a direct current/alternating current convertor, an upper coil, a lower coil, and an inverter. A turning joint for an electric excavator (or a hybrid excavator) uses the principle of a transformer to transmit electric energy from the upper portion of the excavator to a travelling body in the lower portion thereof. Thus, even while an upper rotator body of an electric excavator performs a rotating operation, electric power can be supplied to a travelling electric motor in the lower portion of the electric excavator, to thereby perform a travelling operation.Type: GrantFiled: November 25, 2010Date of Patent: May 24, 2016Assignee: VOLVO CONSTRUCTION EQUIPMENT ABInventor: Ji-Yun Kim
