摘要： A self-propelled electric concrete saw having at least two electric motors. A first electric motor of the concrete saw is powered by an external power supply and can power both a saw blade and a drive system. A second electric motor of the concrete saw is powered by a rechargeable battery and can power the drive system. The concrete saw can be maneuvered by using the second electric motor with or without the concrete saw being connected to the external power supply.

摘要： A hybrid concrete saw includes a saw blade, an internal combustion engine having an output shaft operably connected to the saw blade, and an electric motor connectable to a battery for receiving power therefrom and having an output shaft operably connected to the saw blade. A transmission is connected to the output shaft of each of the engine and the electric motor and the saw blade. A clutch selectively decouples one of the engine and the electric motor from the transmission. A controller controls operation of the engine and the electric motor. The concrete saw is operable in a first mode where the saw blade is driven solely by the engine, a second mode where the saw blade is driven solely by the electric motor, and a third mode where the saw blade is driven by both the engine and the electric motor.
