Battery-driven hydraulic excavator

摘要

There are provided an electric motor driven by (electric) power from a battery; a hydraulic pump driven by the electric motor; a hydraulic motor driven by operating oil discharged from the hydraulic pump; an operating member for performing a predetermined operation by the drive of the hydraulic motor; and operating levers for operating the operating member by switching a flow and a shut-off of the operating oil discharged from the hydraulic pump. The operating levers are operatable between a neutral position at which the hydraulic motor stops operation and an operating position at which the hydraulic motor operates. An accel-trimmer is provided to adjust the supply amount of power from the battery to the electric motor in the state where the operating levers are operated to the operating position.
