Special Solutions / Custom Crane Construction for Single-Girder Cranes by Dahs

Dahs is renowned for its customized special solutions in the field of single-girder cranes and, of course, for double-girder cranes as well. We offer specially adapted systems and technologies to maximize the performance, efficiency, and lifespan of your cranes. These individual solutions take into account both static requirements and operational optimizations to provide you with the best possible outcome for your specific needs. Our experts develop innovative concepts that improve your operational processes while simultaneously increasing the safety and efficiency of your crane systems.

Switchable Motor Poles and Frequency-Controlled Drives for the Single-Girder Bridge Crane
Dahs offers a variety of motor solutions that enable precise control of lifting movements. For special requirements, switchable motors with two speed settings are available, allowing easy adaptation to different lifting needs. In addition, we offer two types of frequency-controlled motors:

• The first type enables a softer load lowering, as the speed is dynamically adjusted to the weight of the load. This is particularly energy-efficient and ideal for applications where energy conservation is a high priority.
• The second type, as part of our premium solutions, maintains a constant lifting speed regardless of the load. This ensures faster lifting operations, especially in applications with frequent use and higher loads, such as in iron storage facilities.

Master/Slave Circuits
For more complex crane systems, we offer a master/slave system for the bridge crane with a transmitter/receiver setup that enables the simultaneous operation of multiple cranes, usually in synchronized control. These circuits ensure that two or more cranes operate in unison, allowing larger loads to be moved more efficiently and safely.

Tandem Operation for Single-Girder Cranes
For particularly demanding lifting operations, Dahs also offers solutions for the tandem operation of single-girder cranes. In tandem operation, two cranes work synchronously to safely and efficiently move particularly large or unwieldy loads. Typically, a common remote control is used as the transmitter and each crane is equipped with its own receiver. This solution is ideal for lifting long or heavy objects that a single crane cannot handle alone – the system then operates in synchronized control. Through precisely coordinated controls and master/slave circuits, it is ensured that both cranes work simultaneously and evenly, optimizing load distribution and increasing safety. Tandem operation is especially advantageous in heavy industry and logistics, where flexibility and capacity are crucial.

Our tandem solutions for trolley cranes not only offer higher load capacity but also increased efficiency in handling complex lifting operations with the single-girder bridge crane. The synchronization of the cranes can be individually adapted to meet the specific requirements of your operations. Whether it is about lifting long materials such as steel beams or large machines – our tandem operation solutions ensure that these tasks are carried out safely and reliably.

Solutions for Optimizing the Lifespan of Trolley Cranes
To maximize the lifespan of your crane systems, we offer various designs characterized by increased load capacity and robustness for the single-girder bridge crane. For the same types of cranes, we provide higher-grade materials that are especially optimized for frequent and heavy loads. This ensures that your crane system remains durable and operates reliably even under extreme conditions.

Static Special Solutions and Height Optimization
For special requirements regarding statics and installation height, we offer specialized variants with a low profile that are optimally adapted to the available space. Dahs also provides various girder suspension options on the head girder, which allow for customization to limited installation heights. This makes it possible to integrate high-performance crane systems even in low halls or rooms without compromising load capacity.

Special Load Distribution and Capacity Utilization
A highlight of our special solutions is the ability to lift more load on the outside of the bridge crane than on the inside when necessary. This special design allows you to maximize the capacity of the crane. Electrically controlled shutdowns ensure that the crane operates safely under these extreme load conditions without risk of overload.

Special Solutions for Outdoor Crane Systems
For outdoor crane systems, we offer specialized solutions that ensure the safe operation of the single-girder bridge crane even under extreme weather conditions. Our cranes can be equipped with heating systems for snow and wind loads, ensuring reliable operation even in harsh environments.
