Variants, Applications and Advantages

A portal crane is a versatile and efficient solution – mobile for various lifting and transport tasks in industry, workshops, and on construction sites. The decision of when to use a large portal crane outdoors rather than an externally built bridge crane system depends on several factors.

Use of Large Portals Outdoors

Large portal cranes are ideal for outdoor use when extensive loads must be moved over greater distances. They offer the following advantages:

• Flexibility: A portal crane can be deployed over large areas with significant width and, depending on the design, is not bound to fixed rails. This allows for flexible positioning and adaptation to various working conditions, for example in warehouses, outdoor storage, and production.
• Higher Load Capacities: Compared to bridge crane systems, large portal cranes can often lift heavier loads, making them an excellent choice for construction sites and warehouse halls.
• Weather Independence: While bridge cranes are mostly installed indoors, large portal cranes can be used even under challenging weather conditions, expanding their range of applications.

Use of Small Mobile Portals Indoors

In indoor environments, for example in warehouses or production, smaller variants of mobile portal cranes (also called “Bockkrane”) are frequently used. These offer the following advantages:

• Space-Saving: Small cranes require less space and are ideal for confined areas in workshops, warehouses, and production facilities where a large bridge crane system would not be practical. At Dahs, products can be adapted in terms of width, girder length, height, and load capacity so that they perfectly and simply support your internal transport. There are also foldable “Bockkrane” available.
• Manoeuvrability: Due to their compact design, small cranes are easier to move and adjust, which is advantageous in production and assembly work.
• Safety: In indoor environments, movement can be restricted by other machines or fixtures. Small cranes minimize the risk of collisions and ensure a safer working environment.

The choice between a large portal crane outdoors and a small portal crane indoors (and the execution of the products as aluminum portal cranes) depends on the specific requirements of the respective application. While large portal cranes are ideal for extensive, heavy loads in open areas, small portal cranes indoors offer the necessary flexibility and safety. In planning, the optimal crane should always be selected to ensure efficiency and safety in the workplace.

Advantages and Disadvantages of an Aluminum Portal Crane Compared to a Steel Portal Crane

Advantages of an Aluminum Portal Crane

• Lighter Weight: The aluminum portal crane is the standard lightweight variant. Aluminum is significantly lighter than steel, making transportation and handling easier. This version is particularly useful when the crane is to be used in mobile applications, as it can be erected and dismantled more quickly.
• Corrosion Resistance: Aluminum is naturally not only light but also more corrosion-resistant than steel, meaning aluminum portal cranes are less prone to rust in moist or corrosive environments. This reduces maintenance efforts and extends the crane’s lifespan in certain applications.
• Easy Installation: Due to its lower weight, an aluminum portal crane can be installed more easily by hand, making the location more flexible and reducing the need for heavy installation tools or machinery.
• Lower Wear: The surface of aluminum is resistant to many environmental influences, leading to lower wear and a longer lifespan, especially in environments with chemical exposures.

Disadvantages of an Aluminum Portal Crane

• Lower Load Capacity: Aluminum portal cranes made of aluminum have lower strength than steel, meaning they tend to have a lower load capacity or narrower dimensions compared to steel models. For applications requiring heavy loads, steel is often the better choice.
• Higher Material Cost: Aluminum is often more expensive than steel, which can increase the acquisition cost of an aluminum portal crane, particularly in larger systems.
• Risk of Deformation: Aluminum is softer than steel and can deform more easily under certain loads or impacts, making aluminum portal cranes more susceptible to mechanical damage in harsh industrial environments.
• Temperature Dependence: Aluminum loses strength more quickly than steel at higher temperatures, which may limit its use in hot environments.

Accessories

Trolleys

• Trolleys are essential for moving loads along the girder of the portal crane. They ensure that loads are precisely transferred from one point to another along the girder. There are manual trolleys, which are moved by hand, and electric trolleys, which are used for heavier loads or faster and more precise movement. A manual trolley can be operated by a hand chain or may be a reel trolley driven by a chain wheel attached to the trolley chain.

Electric Chain Hoists

• Electric chain hoists are a common accessory choice to efficiently lift and lower heavy loads. They are electrically operated and offer high load capacity with minimal effort. These are especially useful for frequent lifting operations and large loads, as they work quickly and reliably.

Hand Chain Hoists

• Hand chain hoists are a manual alternative to electric chain hoists. They are ideal for applications where lifting is less frequent or requires greater precision, as they do not require an external power supply. Hand chain hoists are robust, cost-effective, and easy to use, though slower than electric hoists.

Electric Winches

• Electric winches provide another option for lifting or pulling loads on portal cranes. This product is the perfect accessory for cranes with high load capacity and often comes with an integrated electric trolley. They are available in manual or electric variants and are used in applications requiring a flexible and versatile solution. They offer advantages over chain hoists, particularly at higher lifting heights or over longer distances.

Undercarriages

• Undercarriages enable the mobile movement of the entire portal crane on rails or directly on the floor. This accessory provides mobility and flexibility, allowing the portal crane to be moved from one location to another. Both manual and motorized undercarriages are available, depending on the application requirements.

Protective Devices and Safety Technology

• Accessories for portal cranes from Dahs GmbH, whether steel or aluminum portal cranes, also include safety devices such as overload protection systems, limit switches, and locking brakes, which ensure that the crane operates safely and reliably. These systems help prevent accidents and guarantee the longevity of the crane and its accessories.

The Selection of the Appropriate Chain Hoist – We Help You Make the Right Decision

The selection of the right electric chain hoist for your column swing crane is crucial for the efficiency and safety of your lifting processes. It is independent of the boom length. A chain hoist must be optimally matched to the requirements of your operation, the type of loads, and the frequency of use. We assist you in finding the ideal chain hoist that meets both your technical requirements and economic considerations.

First, we analyze the planned applications of the chain hoist together with you. Factors such as load capacity, the type of loads (e.g., delicate or bulky goods), lifting height, and required lifting speed play a key role. For lighter loads, manual chain hoists are suitable, while for heavy loads or frequent use, electrically operated chain hoists are the better choice as they significantly accelerate work processes and make operation more comfortable.

Another important aspect for the electric chain hoist is the lifting speed. In high-cycle operations with a high throughput, it is advisable to choose a chain hoist with variable speed or a higher base lifting speed. We ensure that the chain hoist not only enhances your efficiency but also meets safety requirements and is compatible with the working environment.

The environment in which the chain hoist is used also plays an important role. In dusty, humid, or corrosive environments, it is crucial to select a chain hoist that is specifically designed for such conditions. We help you identify the appropriate protection classes and materials to ensure a long service life and reliable operation.

Finally, we advise you on choosing the right control system. Depending on the application and user requirements, we offer various control options ranging from simple manual operation to advanced remote-controlled systems. These systems allow the chain hoist to be operated from a safe distance, thereby increasing both comfort and safety.

With our extensive experience and expertise in lifting technology, we support you at every step of the selection process. Together, we will find the chain hoist that is precisely tailored to your operational requirements and ensure that you receive an efficient, safe, and long-lasting solution.

Installation and Foundation Mounting of a Column Swing Crane

The installation and floor mounting of a column swing crane are complex and crucial steps to ensure that the crane operates efficiently and, most importantly, safely at all load capacities. As part of our comprehensive service, we handle the entire installation of your crane—from the initial analysis of the site conditions to the final commissioning and fine-tuning. Every phase of the installation is carefully planned and executed to ensure maximum stability and long-term reliability.

Before installation begins, a detailed site analysis is conducted. Our specialists examine the floor conditions and available space at the installation site to ensure the best possible anchoring and positioning of the crane. Since the floor mounting plays a central role in load bearing and stability of the column swing crane, we assess whether the existing foundation can withstand the stresses of the crane’s weight and the loads to be moved. If necessary, a new, specially reinforced foundation is constructed to meet the required static conditions.

The actual installation of the column swing crane begins with the precise alignment of the column, which must be perfectly vertical to allow for even and smooth swinging operation. Any misalignment could impair functionality and lead to increased wear or even hazardous situations. Our technicians use state-of-the-art measuring instruments to ensure perfect alignment. The column is then securely connected to the prepared foundation.

For floor mounting, we use high-strength anchor bolts (composite anchor systems, anchor screws), depending on the type of foundation. These fastening elements are deeply embedded in the concrete and are designed to withstand extreme loads and dynamic forces acting on the crane due to swinging movements and load acquisition. We ensure that the floor anchoring meets both static requirements and is capable of withstanding the forces generated by the crane’s movement. The composite anchor system plays a crucial role in the safe and long-lasting mounting of column swing cranes. These high-load anchors are embedded deep into the concrete foundation and provide an extremely stable connection between the crane and the floor. They are designed to reliably absorb forces such as swinging movements and load acquisitions during operation. The composite anchor system is ideal for industrial applications where high stability and safety are required.

After the column is anchored, the swing arm and mechanical components are installed. Our specialists ensure precise adjustments for smooth swinging operation. The joints and pivot points are carefully inspected, lubricated, and aligned to ensure quiet and smooth operation. Depending on the crane model and customer requirements, lifting devices (e.g., electric or manual hoists) are also installed and calibrated.

Once the crane is fully installed, we conduct comprehensive tests, including both static load tests and dynamic movement tests, to ensure that the structure can withstand the forces and that the swing arm functions correctly. Our experienced team ensures that the crane meets the highest safety standards and is ready for everyday operation.

The floor anchoring and precise installation of a column swing crane guarantee that the crane remains stable and safe under maximum load. Our extensive expertise and use of modern techniques ensure that your crane is reliable, durable, and safe. This meticulous installation process is critical to the success and efficiency of your crane operations, which is why installation and floor mounting are an integral part of our comprehensive service.

Load Capacity of Column Swing Cranes

The load capacity of a column swing crane is one of the most important factors when selecting and operating this lifting device. It defines how much weight the crane can safely lift and move without compromising structural integrity. Our column swing cranes are available in a variety of load classes to meet the specific requirements of different industries and work environments. We offer solutions with load capacities ranging from 125 kg up to several tons, depending on the loads to be lifted.

For lighter applications in workshops, production lines, or small warehouses, cranes with lower load capacities that still allow precise and efficient operation are suitable. In industrial settings where heavy machinery or components must be lifted, cranes with higher load capacities are used. These cranes can easily handle loads of several tons, making them ideal for large production facilities, shipyards, or construction projects. The high load capacity ensures that even the heaviest loads can be moved safely and efficiently.

Another advantage of our column swing cranes is their modular design, which allows the load capacity to be scaled according to requirements. For customers who frequently handle heavy loads, we provide cranes specifically designed for continuous operation under load. These cranes are characterized by robust construction, high-quality materials, and durable mechanisms that ensure consistent performance even under intensive use.

When selecting the right crane, it is important to consider not only the maximum load but also the operating environment. Depending on the application, additional safety features can be integrated to ensure that the crane operates reliably even under extreme conditions. Our experts will advise you to ensure that the crane's load capacity is precisely tailored to your operational requirements, ensuring safe and long-lasting operation. The correct load selection not only maximizes efficiency but also extends the crane's lifespan and minimizes the risk of damage or accidents.
