PROBLEM TO BE SOLVED: To provide a boom lift enabled to prevent deterioration of a battery by reducing regeneration power.SOLUTION: When an operation to lower a lift mast is performed by a lift operation lever in the state of a battery voltage detector detecting that a battery 14 is charged to less than full charge, a vehicle controller 12 and a lift inverter 13a control regeneration of a lift motor 16 so as to lower the lift mast at a speed corresponding to the operation and store the power obtained by the regeneration in the battery 14, whereas when an operation to lower a lift mast is performed by the lift operation lever in the state of a battery voltage detector detecting that a battery 14 is charged to substantially full charge, the vehicle controller and the lift inverter control driving of the lift motor 16 so as to suppress a regeneration amount of the lift motor 16, or to cause consumption of power. |
