A hybrid construction machinery, comprising electric motors (6, 7, 13, 15, 23, 25) capable of being operated with a power from a generator (11) driven by an engine (10), a power from a main battery (12) to which the power from the generator (11) can be charged, and a power from an auxiliary battery (42), and a selector switch (43) capable of switching so that, in normal operation, the electric motors (6, 7, 13, 15, 23, 25) are operated with at least one normal power of the powers from the generator (11) and the main battery (12) while, in an emergency operation in which the electric motors (6, 7, 13, 15, 23, 25) cannot be operated with the normal power, the electric motors (6, 7, 13, 15, 23, 25) are operated with an auxiliary power from the auxiliary battery (42). |
