<p>This hybrid hydraulic shovel (1) is provided with an engine (17), a generator motor (19), a capacitor (25), a swing motor (23), a transformer (26), a transformer temperature sensor (50), a capacitor temperature sensor (51), and a hybrid controller (C2). On the basis of the temperature of the transformer (26) detected by the transformer temperature sensor (50) and the temperature of the capacitor (25) detected by the capacitor temperature sensor (51), an overheating suppression control unit (C21) of the hybrid controller (C2) changes the amount of the power generated by regeneration by the swing motor (23) to be supplied to the capacitor (25) and the amount thereof to be supplied to the generator motor (19).</p> |
