| 摘要 |
<p>The invention relates to a crane comprising a diesel-electric drive (11), the three-phase generator (11b) of which supplies an AC voltage circuit (12), further comprising a DC voltage circuit (17) connected to the AC voltage circuit (12), electric motors which drive at least one rotating mechanism (d), a lifting mechanism (h) and a luffing mechanism (w) of the crane, at least one brake resistor (14), and a short-term energy store (13), which is connected to the AC voltage circuit (12) or to the DC voltage circuit (17) for the intermediate storage of excess energy. At least one of the electric motors is connected to the AC voltage circuit (12) and at least one is connected to the DC voltage circuit (17), and the AC voltage circuit (12) is connected to the DC voltage circuit (17) via a rectifier (16) such that an energy exchange is possible between the AC voltage circuit (12) and the DC voltage circuit (17).</p> |
