Einträger- vs. Zweiträger-Brückenkräne: Die beste Wahl für Ihr Unternehmen?

Introduction to Bridge Cranes

Verstehen der Grundlagen

What are Single Beam Bridge Cranes?



Single beam bridge cranes, also known as single girder cranes, are designed for lighter loads, typically handling capacities up to 20 tons. They feature a singular bridge beam and are known for their simplicity and ease of maintenance. Ideal for small to medium-sized operations, these cranes are a cost-effective solution, often costing 20-30% less than their double beam counterparts for the same span and lifting capacity.

The Double Beam Bridge Crane Explained



Double beam bridge cranes, or double girder cranes, support heavier loads, often exceeding 20 tons and reaching up to 100 tons or more. With two parallel beams, they offer enhanced stability and are built for large-scale industrial applications. These cranes are typically 50-60% heavier than single beam cranes, leading to higher costs in both installation and operation.

Detailed Comparative Analysis

Diving Deeper into Specifications

Load Capacity and Span Length

Single beam cranes usually operate efficiently with span lengths up to 65 feet and a maximum load capacity of 20 tons. In contrast, double beam cranes can handle span lengths over 65 feet and lift heavier loads, making them suitable for operations requiring extended reach and higher lifting capacities.

Structural and Operational Differences

The single beam design is less complex, resulting in lower manufacturing costs and easier installation. However, for double beam cranes, the dual-girder construction offers better load distribution, reducing wear and tear and enhancing durability. This is particularly crucial for facilities operating cranes for extended periods or under harsh conditions.

Practical Considerations for Businesses

Matching the Crane to Your Needs

Evaluating Facility Requirements

Facilities with limited headroom may benefit more from single beam cranes due to their compact design. On the other hand, if a facility requires heavy-duty lifting with high precision, a double beam crane, with its added stability and capacity, would be the better choice.

Long-Term Cost Implications

While single beam cranes are less expensive initially, their maintenance costs can be higher if used beyond their intended capacity. In contrast, double beam cranes, though pricier upfront, offer longevity and reduced maintenance costs for heavy-duty applications, potentially leading to cost savings in the long run.


Selecting the Optimal Crane for Your Enterprise

In summary, the decision between single and double beam bridge cranes should be based on a thorough analysis of your operational needs, facility specifications, and long-term financial planning. Einträgerkräne offer a cost-effective solution for lighter loads and smaller spans, while double beam cranes are suited for heavy-duty applications requiring stability and higher lifting capacities. Balancing these factors will guide you in making the best choice for your business’s unique requirements.
