BATTERY-DRIVEN CONSTRUCTION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide battery-driven construction equipment which can effectively cope with the depletion of the changing of a built-in battery. SOLUTION: The battery-driven construction equipment activates a hydraulic pump by the built-in battery as a driving source, and drives a plurality of actuators by using hydraulic pressure generated by the hydraulic pump. The battery-driven construction equipment is formed of: a commercial power source connector and an external battery connector; an AC-DC converter for converting commercial alternating power inputted via the commercial power source connector into a direct current, and supplying it to a hydraulic pump driving system by the built-in battery; and a voltage adjuster for voltage-converting direct current power inputted via the external battery connector, and supplying it to the hydraulic pump driving system by the built-in battery.
