Case Study: Elevating Serbian Industry with Precision Engineering

—How Dongqi Crane Delivered a Tailored 5-Ton European Single-Girder Overhead Crane to a Serbian Factory

Introduction

In 2024, Dongqi Crane solidified its global reputation for reliability and innovation by designing, manufacturing, and delivering a high-performance European-style single-girder overhead crane to a manufacturing plant in Serbia. With specifications of 5T capacity, 24M span, 7.4M lifting height, and 380V/50Hz/3P power supply, this crane was engineered to optimize workflow, enhance safety, and support the client’s industrial operations. This case study explores how Dongqi Crane’s solution addressed the customer’s needs through intelligent design, robust construction, and seamless international collaboration.

Project Background

The Serbian client, a prominent player in the manufacturing sector, required a crane that could handle precise material handling tasks across a 24-meter-wide facility while operating efficiently under local power standards. Key challenges included:

• Maximizing floor space utilization in a constrained layout.
• Ensuring smooth and precise load movement for repetitive lifting tasks.
• Adhering to European safety and performance standards.
• Delivering a durable, low-maintenance solution suitable for daily industrial use.

Dongqi’s Customized Solution

Dongqi Crane responded with an HD-type 5-ton European single-girder overhead crane, a compact yet powerful design known for energy efficiency, smooth operation, and ease of maintenance. The crane’s core features included:

1. Optimized Structural Design
   • The 24-meter span was engineered with a high-strength single girder, reducing deadweight while maintaining rigidity and deflection control.
   • The 7.4-meter lifting height allowed the client to fully utilize vertical space, accommodating stacked materials and varying production stages.
2. European-Style Hoist and Controls
   • Equipped with a compact hoist system following European design principles: lighter weight, higher duty cycle, and superior positioning accuracy.
   • The 380V/50Hz/3P motor and electrical components were configured to match local power grids, ensuring stable performance and compliance with Serbian regulations.
3. Enhanced Safety and Usability
   • Integrated safety features included overload protection, limit switches, emergency stop, and anti-sway technology.
   • The crane operated with minimal noise and vibration, promoting a safer and more comfortable working environment.
4. Adaptability for Future Needs
   • Modular design allowed for potential upgrades or modifications, extending the crane’s service life and adaptability to evolving production lines.
