The electrification process affects every sector of mobility, including working machines. Bulldozers, excavators and other technical machines powered by electricity are certainly nothing new, but during the current edition of CES in Las Vegas, Doosan Bobcat He unveiled what he called the world’s first fully electric excavator. What do they mean by this statement?
the Bobcat T7X, that is its name, in addition to having an electric drive, the first to completely abandon the classic hydraulic system of movement of the arms and the bucket. In fact, the classic oil-filled pistons have been replaced by System of actuators and electric motorsthat do not require fluids. It is all powered by a 67 kWh battery.
That’s why the T7X only uses approx liters of refrigerant (which Bobcat also calls environmentally friendly), instead of dozens of liters of petroleum derivatives. So in addition to being zero emissions for movement, it is also for its mechanisms, reducing noise in the working environment, reducing vibrations, and providing Instant and adjustable torque more easily. Moreover, the operator does not have to respect any “warm-up” time.
Expensive prototype then? Not at all, the Bobcat T7X received CES Awards for Innovation in the Vehicle Intelligence, Transportation and Smart Cities category, as well as the interest of Sunbelt Rentals, one of the top US rental companies, which will acquire a massive fleet of over 1,000 stores.
