Client Profile & Operational Challenge
In 2024, a manufacturing facility in Portugal required a significant upgrade to its material handling infrastructure. Their primary need was for a reliable, efficient, and spatially optimized lifting system to support diverse production workflows. The challenge involved outfitting the main workshop with precise overhead cranes while also addressing a critical lifting requirement in an external area where a standard overhead crane could not be installed. The solution needed to ensure smooth operation, safety, and adaptability to the existing building layout.

Dongqi Crane’s Integrated Solution
Dongqi Crane provided a complete, custom-engineered package comprising two main subsystems: a suite of indoor overhead cranes and an externally installed semi-gantry crane.

1. Indoor Workshop System: HD Series Double Girder Overhead Cranes
To maximize efficiency within the main production hall, we supplied a coordinated fleet of six HD series cranes with capacities ranging from 2 to 10 tons. Each crane was tailored to its specific task and location:

• Precise Span Configuration: The cranes were built to exact spans matching the workshop’s column spacing, including specific dimensions like 16.695m, 16.67m, and 7.8m. This ensured optimal coverage and seamless movement across the entire work area.
• Uniform Performance with NR Hoists: All HD cranes were equipped with NR-type European-style electric wire rope hoists. This choice offers key benefits:
  • Optimized Headroom: The compact design of the NR hoist maximizes usable lifting height—a crucial factor in facilities with the standard 6-meter (H6M) clearance specified here.
  • Control and Reliability: These hoists provide smooth and precise load positioning, essential for careful handling of materials and components in a busy manufacturing environment.
• Capacity Planning: The mix of capacities (10T, 5T, 3T, 2T) allows the client to assign the right tool for each job, from heavy primary lifts to lighter, frequent tasks, improving both safety and workflow efficiency.

2. External Area Solution: Custom-Installed BMGO Semi-Gantry Crane
For lifting operations required outside the main workshop, a standard overhead crane was not feasible. Our solution was a BMGO32T-6.2M H7M semi-gantry crane.

• Adapting to Site Constraints: The semi-gantry design, with one end running on a ground-mounted leg and the other on an elevated runway, was ideal for the location.
• Complete Support Structure Provision: Dongqi Crane did not just supply the crane. We designed and built a full steel support structure and track system, securely anchored to the factory’s exterior wall. This turnkey approach guaranteed a stable, robust foundation for the 32-ton capacity crane, which also features a greater 7-meter lifting height for external handling needs.
• Seamless System Integration: This externally located crane operates on the same 380V, 50Hz, 3-Phase power standard as the indoor cranes, ensuring operational consistency and ease of maintenance.

Project Outcome & Value Delivered
The complete system was successfully installed and commissioned. The Portuguese client now operates an integrated lifting network:

• Inside the workshop: A flexible fleet of overhead cranes streamlines material movement directly along production lines.
• At the exterior area: The powerful semi-gantry crane handles heavy loads, facilitating logistics like loading/unloading and outdoor storage tasks.

This project demonstrates Dongqi Crane’s capability as a solutions provider, not just an equipment supplier. We combine product expertise (like the efficient HD cranes and versatile BMGO gantry) with full-service engineering—from precise span customization to designing and erecting complete support structures—to solve specific spatial and operational challenges.
