Executive Summary

In 2024, Dongqi Crane designed, manufactured, and successfully installed a custom QDX double-girder overhead crane for a manufacturing plant in Argentina. One year after installation, the client has reported exceptional performance, seamless integration into their workflow, and high reliability. This case study details the project’s requirements, the tailored solution provided, and the tangible benefits realized, showcasing Dongqi’s capability to deliver world-class lifting solutions for the global industrial sector.

1. Project Background & Client Challenges

The Argentine client, a prominent player in the manufacturing sector, required a robust and precise lifting solution for their key production workshop. Their operations involved handling heavy raw materials and assembled components, demanding a crane that was not just powerful, but also accurate, reliable, and perfectly adapted to their facility’s physical constraints.

The primary challenges were:

• Precise Spatial Requirements: The crane needed to operate within a strict span of 17.18 meters and provide a lifting height of 6 meters, utilizing the workshop space optimally without any wasted clearance.
• Versatile Lifting Needs: Production processes required handling both very heavy loads and lighter, more precise tasks, pointing to the need for a dual-hoist system.
• Demanding Operational Environment: The crane had to guarantee safety, durability, and low maintenance under regular industrial use.
• International Supply Coordination: The client needed a reliable supplier capable of managing the entire process from design to overseas delivery and installation support.

2. The Dongqi Solution: A Tailored QDX Double-Girder Crane

After a thorough consultation, Dongqi engineers recommended and delivered a customized QDX model double-girder overhead crane. This solution was selected for its superior structural integrity, operational flexibility, and proven performance in heavy-duty industrial applications.

Core Technical Specifications:

• Model: QDX Double-Girder Overhead Crane
• Lifting Capacity: Main Hoist 20 metric tons / Auxiliary Hoist 3 metric tons
• Span: Precisely 17.18 meters
• Lifting Height: 6 meters
• Power Supply: 380V, 50Hz, 3-Phase (Standard for the region)

Key Features & Design Advantages:

• Dual-Hoist System for Enhanced Flexibility: The combination of a powerful 20T main hoist and a nimble 3T auxiliary hoist allows the client to handle a wide range of tasks efficiently—from moving massive loads to performing precise, lighter lifts—without needing multiple cranes.
• Optimized Structural Design: The double-girder structure provides exceptional strength and rigidity, ensuring minimal deflection and smooth, stable travel even when handling loads at full capacity across the entire 17.18m span.
• Precision Control & Safety: Equipped with advanced frequency control systems on travel and hoisting motions, the crane ensures smooth acceleration and deceleration, accurate load positioning, and safe, operator-friendly control.
• Built for Durability: High-quality components, including robust wire ropes, reliable motors, and hardened wheels, were selected to withstand intensive use and minimize long-term maintenance needs.

3. Implementation: Seamless Delivery & Professional Installation

Dongqi managed the project from concept to operational handover.

1. Detailed Planning: Engineers finalized designs based on precise workshop measurements and client workflow input.
2. Manufacturing & Quality Control: The crane was built to order in Dongqi’s facilities, undergoing stringent quality checks at every production stage.
3. Packaging & Shipment: All components were professionally packaged and shipped to Argentina, with clear documentation for ease of customs clearance.
4. Installation & Commissioning: Dongqi provided comprehensive installation guides and remote support. The client’s team, using the detailed installation photos we provided as a reference, completed the erection efficiently. Final electrical checks and commissioning tests were performed to ensure everything met operational standards.

4. Results & Client Feedback After One Year of Operation

After 12 months of continuous service, the client has confirmed the project as a complete success.

Reported Outcomes:

• Increased Productivity: The crane’s reliability and the flexibility of the dual-hoist system have streamlined material handling, reducing downtime and accelerating production cycles.
• Excellent Reliability: The crane has operated flawlessly with zero major issues, confirming the durability of its construction and components.
• Perfect Fit: The custom span (17.18m) and lift height (6m) have proven to be ideal for the workshop layout, maximizing coverage and utility.
• Positive User Feedback: Operators appreciate the smooth controls and precision, which enhance both safety and ease of use.

In the client’s own words, their feedback highlights: “We are very satisfied with the QDX crane supplied by Dongqi. After one full year of operation, it has proven to be a robust, reliable, and indispensable part of our daily production. The quality exceeds our expectations, and the design perfectly matches our needs.“
