The rising/falling means includes the electric cylinder that moves forward and backward a rod part projecting from a cylinder part by the electric motor. The electric motor is driven and controlled by control means having an inverter unit. The rising/falling means includes the one electric cylinder disposed at the lower end of the boom. At least one driving and controlling means of the electric cylinder are disposed for the electric cylinder, preferably disposed on both sides via the electric cylinder. |
