Dahs Double-Girder Crane – Maximum Power for Heavy Loads!

Double-girder bridge trolley cranes / double-girder bridge cranes, or double-girder crane systems, are typically large cranes that, unlike single-girder cranes, consist of at least two head girders and two main girders (profile or box girders). As high-performance cranes, these trolley cranes from Dahs GmbH impress with their double-girder design, offering maximum load capacity and span. They enable the safe and precise transport of large and bulky loads.

Our representatives are happy to advise you on your Dahs GmbH double-girder crane regarding design, type, lifting devices, special features of the crane’s electrical system, installation, and accessories. Our double-girder cranes / double-girder trolley cranes can be optimally integrated into both existing and new hall constructions, ensuring consistently high quality of crane components and ease of operation of our lifting technology. As an electrical specialist, we can particularly offer excellent solutions for special requirements in crane electrics. Of course, we are also happy to handle the installation for your single-girder crane, double-girder crane, or other trolley cranes.

Selection Criteria for a Double-Girder Crane / Double-Girder Trolley Crane

• What loads should be lifted with the double-girder crane / double-girder trolley crane (weight and type of loads)?
• What span is required for the double-girder crane / double-girder trolley crane and what spans are feasible?
• How high must the lifting height of the double-girder crane be (hook height)?
• What load capacity is needed?
• What type of travel and lifting speed is desired for the double-girder crane?
• Are special safety functions and features required for the double-girder crane (e.g., overload protection, emergency stop systems)?
• How frequently will the double-girder crane / double-girder trolley crane be in operation (daily cycles)?
• What power supply or energy source is available at the installation site?
• Are there any special environmental conditions (e.g., extreme temperatures, humidity, dust, explosion-protected environments) for the double-girder crane?
• Are special control requirements necessary (manual, electric, remote-controlled)?
• Will the crane be fixedly installed or does it need to be mobile (e.g., on steel rails)?
• How will maintenance and servicing of the trolley cranes be organized?
• Will the double-girder crane / double-girder trolley crane be connected to existing systems or facilities?

Options, Accessories & Installation

Double-girder trolley cranes from Dahs GmbH are one of the most efficient and robust solutions when it comes to heavy or higher loads and demanding lifting operations. The double-girder crane often operates more smoothly than a single-girder crane and can work more precisely at higher loads compared to a single-girder crane. Especially when combined with the right accessories and professional installation, they offer companies optimal performance. As your competent partner, we provide you with customized solutions for double-girder cranes, including installation and a broad range of accessories, such as:

• Load Handling Devices for the Double-Girder Bridge Crane:
  • Type Gripper: Specifically designed for bulk materials, scrap, or wood.
  • Type Magnets: For the transport of metal parts.
  • Type Clamps: For the safe lifting of panels, pipes, or other specific goods.
  • Type Hooks: A universal solution for various loads.
• Lifting Mechanisms:
  • Rope Hoist: The standard lifting device for double-girder bridge cranes. Here, the lifting height is decisive for the price since rope hoists can only be wound in a single layer.
  • Electric Chain Hoists: For precise and automated lifting operations of the crane system. They are used for double-girder bridge cranes only in special cases.
  • Winches or Chain Hoists: Depending on the lifting requirements and load weight of the crane systems. A chain hoist is rarely used for double-girder bridge cranes, usually only rope hoists are employed.
  • Electric Chain Hoists: For precise and automated lifting operations of the crane system. They are used for double-girder bridge cranes only in special cases.
• Radio Remote Controls: Enable flexible and safe operation and the ability to call the crane from a distance.
• Safety Devices:
  • Load Stops: Prevent overloading of the crane or crane system.
  • Limit Switches: Secure the double-girder bridge crane against exceeding the rail limits of the bridge cranes.
  • Safety Lights and Warning Signals: Alert when the double-girder bridge crane is in motion.
• Frequency Converters: Allow stepless regulation of the crane movements for both the drive systems and the lifting system for precise operation, depending on the type.
• Load Indication Systems: This accessory displays the current load weight and various operating parameters of the cranes in real time.
• Trolleys: Additional lifting devices facilitate the lateral movement of loads, whether manually or electrically operated.
• Crane Rails and Rail End Buffers: For precise guidance of the cranes on the rail.
• Rotary Devices: This accessory facilitates the rotation of loads on the double-girder bridge crane during the lifting process.
• Automation Systems: Increase efficiency by automating repetitive tasks of the cranes.
• Protective Devices for Outdoor Use: Protect the electronics and mechanics of your product from weather influences.
• Maintenance Platforms: Provide safe access for any bridge crane for maintenance and repairs.
• Explosion-Protected Cranes: Upon request, our representatives can configure explosion-protected trolley cranes with ATEX approval. Explosion-protected indoor cranes are particularly used where flammable, explosion-protected materials are handled.
