1. Understanding the Client’s Challenge

The Argentine client required a robust lifting solution for their factory’s key production bay. The primary challenges were:

• Space Optimization: The workshop had specific dimensional constraints, requiring a crane with a precise span of 17.18 meters to maximize floor coverage without structural modifications.
• Versatile Load Handling: Production processes involved handling a variety of components, necessitating a dual-capacity system—a main hook for heavy 20-ton loads and a more agile 3-ton auxiliary hook for smaller parts and precision work.
• Demanding Operational Reliability: As a critical link in their manufacturing line, any crane downtime would directly impact overall productivity. They needed a machine built for long-term, dependable performance with minimal maintenance.

2. The Dongqi Solution: Customized Engineering for Performance

Dongqi Crane engineers developed a tailored QDX double-girder crane solution, focusing on precision, durability, and safety.

• Precision-Matched Design: The crane was manufactured to the exact 17.18m span and 6m lifting height, ensuring a perfect fit within the client’s existing building structure and workflow.
• Dual-Hook Efficiency: The 20/3-ton dual-hoist configuration provided unparalleled operational flexibility. The main hoist handles primary heavy lifting, while the auxiliary hoist significantly improves efficiency in staging, tooling, and handling lighter materials, reducing cycle times.
• Robust Construction & Advanced Control: The QDX design features a rigid double-girder structure for stable and sway-free load movement. Equipped with a frequency control system on all motions, it ensures smooth acceleration and deceleration, enabling pinpoint load positioning and enhanced safety for both the cargo and operators.

3. Project Execution: Seamless Installation & Commissioning

The successful installation, documented in the photos provided by the client, was a key phase of the project.

• Professional On-Site Management: Dongqi’s team ensured all components, including pre-assembled bridge girders, end trucks, and the hoist assembly, were accurately installed on the runway beams.
• Systematic Testing & Client Training: Following installation, comprehensive testing was performed—from no-load trials to rated load and overload tests. Client operators and maintenance personnel received thorough training on safe operation and routine inspection procedures.

4. Results & Client Feedback: A Year of Reliable Service

After 12 months of continuous operation, the client reports excellent performance.

• Enhanced Productivity: The crane’s reliability and the dual-hoist functionality have streamlined material handling processes in the bay, directly contributing to smoother production flow.
• Proven Durability: Operating in an industrial environment, the crane has required only scheduled maintenance, demonstrating the quality of its components and construction.
• Verified Satisfaction: The client’s proactive sharing of positive feedback and installation photos stands as a strong testament to their satisfaction. They appreciate not only the product’s quality but also the professionalism of the entire Dongqi project team, from initial consultation through to after-sales support.
