RTG / ARTG Freerider Cantilever

Kuenz offers a new and unique gantry design in which the main girder is oval-shaped, which minimizes wind resistance. The rounded design allows the crane to operate using less drive power and energy. Additionally, the dynamic forces on the crane’s wheels, runway and structure are reduced. The result is a lower gantry weight, meaning fewer wheels and less load on each one, with the added benefit of lower noise levels.

As a global leader in innovation, Kuenz builds automated functionality into nearly all its products. By eliminating human error and removing people from dangerous environments, we are making workplaces safer and more efficient.

Fully automated Kuenz Tankhouse Cranes have been active for decades in copper and zinc production. At seaports around the world, our fully Automated Stacking Cranes move containers without the need for human involvement. Furthermore, Kuenz Container Cranes in intermodal terminals are delivered and retrofitted with various levels of automation.

Customers benefit from automation through increased productivity as well as a safer and more comfortable working environment.

Moving semi-trailers is time-consuming and requires additional ground personnel. Kuenz has solved this challenge by developing special gripper cameras which make handling semi-trailers safer and easier. Eight cameras are installed on the inside of the piggyback arms of the spreader, providing visual coverage of the areas around the gripping corners. The images are displayed in the crane cabin or at the remote operation station. The positions of all four grippers are clearly visible so the semi-trailer can be safely taken in the right place. At night, the area is illuminated by LEDs. With the new camera system Kuenz significantly increases the safety and efficiency of semi-trailer handling.

Intermodal terminals are increasingly being built in residential areas and must therefore comply with noise restriction standards. Kuenz Soft Landing is an innovative assistance system that reduces noise emissions, increases productivity and protects the lifting equipment and cargo from damages. A digital stack map is created with all containers of the block. The system then knows the stack heights and reduces the speed automatically and just in time before landing. This ensures a significant reduction of noise emissions and an extended equipment lifetime.

It is normal that things break over time but finding the reason behind it can take long. CMS can help you deal with this problem:

• Getting information via alarms
• Tracking down the cause by looking at the trend of the system states

Using the maintenance plan implemented on each crane at the CMS can help to:

• Plan your maintenance in advance
• Get preventive maintenance points, where the time is based on historical data
• Add your personal maintenance points, appearing regularly or only once
• Reduce predefined maintenance periods additionally if desired, e.g. cable interval might decrease the last weeks before exchange
• Check maintenance work after it is done
• Export final list of maintenance points

Hoist, trolley, and gantry are driven by highly efficient electric motors. Therefore, the typical disadvantages of hydraulic systems, like environmental pollution, poor efficiency, and high maintenance costs, are eliminated.

The energy which results from braking or lowering is used to charge the battery. This reuse of energy leads to a significant boost regarding overall efficiency.

Kuenz has decades of experience in the crane industry. The resulting knowledge is the basis for the optimized design ensuring low maintenance costs and safe access to all maintenance positions.

• Platforms for inspections and maintenance
• Safe and easy access to all maintenance points
• Safe maintenance position of the spreader directly on ground level
