Battery-powered fully electric rough terrain crane “EVOLT eGR-250N”
Tadano announced on December 6th that it will release the world’s first battery-powered fully electric rough terrain crane “EVOLT eGR-250N” with a maximum lifting capacity of 25 tons from December 8th, 2023. The price is 148 million yen (excluding tax). The EVOLT eGR-250N is a rough terrain crane with a lifting capacity of 25 tons that operates entirely on batteries for all crane work and travel operations, making it the world’s first fully electric crane to be put into practical use.
The EVOLT eGR-250N has the same driving performance and crane performance as a model equipped with a conventional diesel engine, and is a product that can handle an average day’s crane work when fully charged, and has a rough lifting capacity of 25 tons. Terrain cranes are in the highest demand in Japan and have the highest versatility, so the decision was made to introduce them to the Japanese market.
Main features of EVOLT eGR-250N
The main features of the EVOLT eGR-250N are the “basic performance that is the same as the previous model”, including a maximum lifting capacity of 25 tons, a maximum working radius of 34 m, a maximum ground lifting height of 44.2 m, and a maximum speed of 49 km/h. In addition to having the same lifting and running performance as the 25t class, it continues to be equipped with the Tadano View System and Setup Radio Control, which are also installed in the company’s G5 series, making it easier to operate and more comfortable than previous models. It is possible to drive.
The noise during driving and crane work has also been greatly improved, and compared to the previous model “GR-250N”, the noise has been reduced from 78 dB to 71 dB during steady running, and from 104 dB to 94 dB during crane work. It provides a new added value of quietness for use in severe workplaces.
Equipped with two high-output motors with a maximum output of 97kW (132PS) and a maximum torque of 2500Nm as driving motors. Acceleration performance has been dramatically improved, and there is no shock when shifting gears, allowing for smooth driving and reducing operator stress.
The driving battery uses a lithium-ion battery with a capacity of 226kWh. As a guideline, the battery can be used for approximately 5 hours of crane work + approximately 42 km of driving time (approximately 11 hours of crane work only and approximately 70 km of driving time), which means that a full charge will allow for an average day of crane work and driving.
In addition, charging time is approximately 2.5 hours for quick charging and approximately 8 hours for normal charging. The quick charging method uses the CHAdeMO method, which is becoming more popular in Japan, and the normal charging uses AC 200V three-phase commercial power, making it possible to perform crane work while plugged in at the work site.
The company positions the EVOLT eGR250N as the first product that will bring it closer to realizing its long-term environmental goals, and will continue to electrify products in other categories such as rough terrain cranes, aerial work vehicles, and crawler cranes for overseas markets. The company has also begun development on the project, and plans to continue to make it more environmentally friendly.
