Doosan Bobcat unveiled the world’s first fully electric construction equipment to the global market through CES 2022, the world’s largest technology exhibition.
Doosan Bobcat held a media day event at the Mandalay Bay Convention Center in Las Vegas to introduce the T7X, which won two CES 2022 Innovation Awards.
The T7X is the world’s first fully electric construction equipment that eliminates all hydraulic components. It is comparable in performance to existing internal combustion engine equipment and emits no harmful substances. Noise has been greatly reduced to one-tenth the level, and energy efficiency has been maximized.
The Doosan Bobcat also has achieved a strategic partnership with Sunbelt Rentals, a rental company in the North American region.

PSR Analysis: Many companies have been actively working on the development of electric construction equipment. Among them, this loader announced by Bobcat is worthy of attention.
It uses an actuator instead of a hydraulic system, eliminating the need for up to 57 gallons of hydraulic oil used in previous models, and only requiring one quart of coolant. This means that the loader requires virtually no fluid, which contributes lower maintenance costs, which will be a big advantage for users.
The power source is a 62kW lithium-ion battery, and the system recognizes the load at the time of operation and automatically reduces the power for light loads to extend the runtime. The system also enables performance analysis through two-way telematics communication.
Performance is comparable to engine models, with zero harmful substances. Noise is 10% of the engine model, vibration is almost zero, and energy efficiency has been maximized. This release is a milestone for electrification in the loader world and may be just what the market needs. I feel that this is a product could be a benchmark for other manufacturers. PSR
