Executive Summary

Dongqi Crane successfully supplied and delivered 20 sets of heavy-duty double girder overhead cranes to a major construction group based in Europe. This equipment is being utilized across the client’s multiple large-scale infrastructure and industrial building projects. The primary objective was to significantly enhance the client’s on-site material handling capabilities, with a focus on improving operational efficiency, safety, and equipment reliability. This project demonstrates Dongqi Crane’s ability to serve as a dependable partner for leading European construction firms requiring high-performance lifting equipment.

The Client: A Leading European Construction Enterprise

The client is a well-established and respected engineering and construction group headquartered in Europe. Their extensive portfolio includes a wide range of complex and demanding projects, such as commercial developments, transport infrastructure, and heavy industrial facilities. They are recognized for their strong commitment to engineering excellence, strict adherence to safety protocols, and the integration of reliable technologies to ensure project success. This reputation requires all equipment suppliers to meet exceptionally high standards of performance and durability.

Challenges and Client Requirements

The client’s operational environment presented several specific and demanding challenges:

• Heavy Load Handling: The cranes are required for frequent lifting of massive prefabricated concrete elements, heavy steel structures, large formworks, and mechanical modules. Individual lift capacities are substantial, typically ranging from 10 to 50 tons per crane.
• High-Intensity Work Cycles: Tight project schedules necessitate equipment that can endure continuous, high-frequency operation with minimal downtime.
• Precision and Control: Operations often occur in confined or complex site layouts. This requires exceptionally smooth and precise crane movement for accurate positioning of loads, which is critical for both installation accuracy and overall site safety.
• Harsh Operating Conditions: The cranes must perform reliably in typical construction site conditions, which include exposure to dust, dirt, and varying temperatures.
• European Standards and Support: The client required equipment that complies with stringent European safety and design standards. Furthermore, they needed a supplier with proven capability to provide clear technical documentation and responsive support for their operations across different European locations.

The Dongqi Solution: Customized Double Girder Cranes

Dongqi Crane proposed a customized solution based on its robust double girder overhead crane design, selected for its inherent strength, stability, and suitability for heavy-duty, high-cycle applications.

Key features of the delivered cranes include:

• Robust Structural Design: The cranes feature an optimized box-girder design fabricated from high-strength steel. This ensures structural integrity for heavy loads while effectively managing the equipment’s self-weight.
• Reliable Hoisting System: Each crane is equipped with high-efficiency hoisting motors, precision gearboxes, and a dual-brake system. This combination guarantees smooth, controlled, and safe lifting and lowering operations.
• Smooth Travel System: The longitudinal and cross travel movements are powered by reliable motors and precision-geared reducers. Hardened steel wheels ensure smooth travel, low noise, and long service life, even under intensive use.
• Advanced Control and Safety: The electrical systems incorporate quality components. Variable Frequency Drive (VFD) control was provided for precise speed regulation, enabling soft starts and stops and accurate load positioning with minimal sway. A comprehensive suite of safety devices is standard, including overload limiters, end approach limit switches, emergency stop buttons, and anti-collision systems, all meeting European directives.
• Comprehensive Service Support: Beyond manufacturing, Dongqi provided detailed technical consultation to tailor each crane to its specific project site. All cranes were manufactured with full compliance to relevant European standards. Dongqi also managed the logistics, ensuring timely delivery to various project locations, and provided detailed installation manuals and support.

Results and Value Delivered

The implementation of the 20 Dongqi double girder cranes delivered significant measurable benefits to the client:

• Enhanced Productivity: The reliability and high performance of the cranes drastically reduced material handling times, directly accelerating critical path activities and supporting on-schedule project progression.
• Uncompromised Safety: The integrated safety systems, built to European standards, and robust build quality provided a fundamentally safer working environment, strongly supporting the client’s strict safety policy on site.
• Reduced Operational Costs: The cranes’ low failure rate and durable construction minimized unplanned maintenance and repair needs, contributing to a lower total cost of ownership over the equipment’s lifecycle.
• Successful Partnership: Dongqi’s end-to-end project management—from technical design and manufacturing to logistics and support—demonstrated a capability that earned the client’s trust for potential future collaboration.

Client Feedback:
“We required a supplier who could provide reliable equipment for multiple sites and handle the technical and logistical details effectively. Dongqi’s cranes have performed well on our projects, and their technical team was responsive to our requirements throughout the process.” — Project Manager, Client Group.

Conclusion

The successful delivery and deployment of 20 double girder cranes for this major European construction group stand as a strong testament to Dongqi Crane’s product quality, engineering capability, and commitment to supporting European customers. Dongqi Crane continues to dedicate itself to providing industrial clients with safe, efficient, and dependable lifting solutions.

Looking Ahead: Dongqi looks forward to continuing to support the European market and fostering lasting partnerships with clients, supporting their future projects with advanced material handling technology and expertise.
