PROBLEM TO BE SOLVED: To provide a construction machine which is favorable in securing running efficiency.SOLUTION: When construction work by a wheel crane 10, a drive pinion gear of a lower structure 12 rotates, and a circular gear of an upper structure 14 rotates, a rotor reverses via a power transmission mechanism. By the reverse of the rotor, a first power generation part generates power, and a battery charge part is charged. When an intermediate boom 1604 is moved in linear direction with respect to a base end boom 1602, the rotor reverses via the power transmission mechanism. By the reverse of the rotor, a second power generation part 32B generates power, and the battery charge part is charged. When a tip end boom 1606 is moved in the linear direction with respect to the intermediate boom 1604, the rotor reverses via the power transmission mechanism, by the reverse of the rotor, a third power generation part 32C generates power, and the battery charge part is charged. |
