GMK5150L-1e and GMK5150XLe models. The ATs are built on the manufacturer’ s existing five-axle, 150-ton capacity GMK5150L-1 and GMK5150XL cranes while featuring a new, fully electrified superstructure.
Up to a full day of emissions-free power is possible with the new Grove models. The battery pack enables approximately five hours of lifting. When the crane is connected to the grid, crane operation can be extended to approximately 20 hours without compromising speed or capacity.
At the heart of the new Grove hybrid cranes is a battery pack with 180 kWh of energy that can be charged from the grid with either AC or DC power, or from a 170-kW generator integrated into the carrier. This set up also allows charging while driving and the cranes can be operated while charging if there is infrastructure at the jobsite.
To eliminate any negative impact on lifting performance, the new Grove cranes feature the same main booms as their diesel model counterparts and use the same load charts. There are also no significant changes to the driveline, the MEGATRAK independent suspension system with disc brakes, the Manitowoc Crane Control System( CCS) with boom configurator mode and the company’ s flexible outrigger positioning system MAXbase.

even drive to the jobsite using HVO fuel to power their Mercedes-Benz engines, which can reduce carbon emissions by up to 90 %,” said Florian Peters, senior product manager for AT cranes at Manitowoc.“ Then, they can set up and use electricity to handle lifting tasks without producing harmful emissions, and there’ s also a massive reduction in noise pollution.”
Fully Electric
Tadano’ s EVOLT eGR-1000XLL-1 delivers the same lifting capability as the manufacturer’ s GR-1000XLL-4 100-ton rough terrain crane while offering up to seven hours of lifting or up to five hours of lifting plus 5.5 miles of jobsite travel with its on-board battery pack. The crane is powered entirely by lithium-ion batteries for both transportation and lifting.
The EVOLT eGR-1000XLL-1 can be charged using standard 480 VAC grid power or a CCS1 rapid charging system. When using 3-phase 480V normal charging with capacity 60A, it takes 4.5 to 5.5 hours to fully charge the battery and rapid charging capabilities can complete a full charge in two to three hours. Regenerative braking also enhances battery longevity and a plug-in capability provides for continuous crane operation.
The Tadano Lift Visualizer system on the EVOLT eGR-1000XLL-1 utilizes a suspended load monitoring camera, allowing operators to see loads directly from above. The Lift Visualizer pulls critical information from the AML control system, including radius, capacities and load, and displays it on a video screen for the operator.
The EVOLT App is also available for use with the eGR-1000XLL-1 rough terrain model. To support jobsite operations, it displays battery status, operating history and distance to the destination.
With an increasing number of jurisdictions enacting stricter environmental requirements on machinery, manufacturers are helping crane operators meet that challenge with new electrically powered designs. In the end, those new options are combining sustainability with maximum efficiency.
