The Sennebogen 673 is a unique powerhouse in the 70-ton class. It combines robust construction, advanced technology, and compact deployability. The Full-Power Boom can telescope under load and continuously offers optimal lifting capacity, without having to pre-select boom lengths. This allows the operator to work faster and more efficiently, regardless of the situation.
What makes the 673 extra versatile is the possibility of variable ballast. With counterweight blocks that can be adapted to the task, you maintain maximum performance without being tied to one configuration. The inward-folding railings on the upper carriage and the double-folding fly jib make transport easier and drastically shorten the set-up time on the construction site.
Thanks to the telescopic crawler undercarriage, the machine remains compact during transport, but can be set up on location for maximum stability. Despite its weight, the crane is easy to move and quickly operational, even under challenging conditions. This makes it ideally suited for urban construction sites, bridge construction, or civil engineering projects where space is scarce.
Ease of use and ease of maintenance have been integrated into the design. Access to maintenance points is optimally arranged; a central lubrication station and easily accessible components save maintenance time and increase availability on the work floor. This facilitates daily use and ensures reliability and durability in the long term.
The cab—the comfortable Maxcab—takes ergonomics to the next level. With a standard tilt of approximately 20°, hydraulically operated remote adjustment, and a seat console that moves with it, it offers an ergonomic working environment. The adjustable joystick control ensures precise control and prevents fatigue during prolonged use. This combination of comfort and overview makes working safer and more efficient.
With its impressive lifting capacity of 70 tons, maximum hook height of 51 meters, and a wide range of tools such as fly jibs, the Sennebogen 673 is an exceptionally versatile machine. It is designed to perform under load—even when turning, swiveling, moving, and precisely placing loads in one movement. This in all circumstances, even on slopes, thanks to 360° rotation and stable management of loads up to 100% capacity during movement.
In short, the Sennebogen 673 offers a unique combination of power, flexibility, ergonomics, and ease of use. Whether it concerns prefab assembly, bridge construction, civil engineering works, or projects with limited space: this machine delivers performance, comfort, and efficiency in one complete, top-performing crane.
