Made to Maneuver
Tadano’s goal in designing these cranes was to maximize maneuverability. Both models feature steered front and trailing axles, with the second and third axles being positioned closer to the center of the crane versus standard axle configurations. This allows for a turning radius that is six feet smaller than on preceding models.
Both cranes are equipped with H-style outriggers, which take up less space than their swing-out counterparts and are able to lift the chassis higher. They can be positioned asymmetrically in cooperation with the crane’s control software to reach maximum lifting capacity. A storage compartment for tools and accessories is located in the body frame.
The three rear axles ride on an air suspension system, allowing for additional roll stability and traction when traveling to and from the job site. Both cranes can be paired with a trailer for transporting additional counterweight.
