Executive Summary

Dongqi Crane successfully supplied and delivered 20 sets of heavy-duty double girder overhead cranes to a major European construction group. This equipment is being utilized across the client’s multiple international infrastructure and industrial construction 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 trusted partner for large international firms requiring high-performance lifting solutions.

The Client: A Leading European Construction Group

The client is a large and well-established construction group headquartered in Europe, with a significant presence in international markets. Their operations encompass the development of complex and demanding projects, including large-scale industrial facilities and public infrastructure. The company is recognized for its strong commitment to engineering excellence, strict adherence to safety standards, and the use of robust technologies to ensure project success. This reputation requires that all equipment suppliers meet high standards of performance and reliability.

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.
• International Standards and Support: The client required equipment that complies with European and other major international safety and design standards. Furthermore, they needed a supplier with proven capability to provide prompt technical support and ensure parts availability across different project locations.

The Dongqi Solution: Customized Double Girder Cranes

Dongqi Crane proposed a customized solution based on its robust QD-type 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 self-weight of the crane.
• 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 brand-name motors and precision-geared reducers. The hardened steel wheels ensure smooth travel, low noise, and long service life, even under intensive use.
• Advanced Control and Safety: The electrical systems incorporate components from internationally recognized manufacturers. Variable Frequency Drive (VFD) control was implemented for precise speed regulation, enabling soft starts/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.
• Comprehensive Service Support: Beyond manufacturing, Dongqi provided in-depth technical consultation to tailor each crane to its specific project site. All cranes were manufactured in full compliance with international standards. Dongqi also managed complex logistics, ensuring timely delivery to various sites in Europe, 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 and robust build quality contributed to a safer working environment, supporting the client’s strict safety policies on site.
• Reduced Operational Costs: The cranes’ low failure rate and durable construction minimized unplanned maintenance and repair needs, contributing to lower total cost of ownership.
• Successful Partnership: Dongqi’s end-to-end project management—from technical design and manufacturing to logistics and support—demonstrated a capability that met the client’s expectations for a major international supply project.
