Project Overview: Integrated Lifting Solution for a Portuguese Manufacturing Plant

In 2024, Dongqi Crane collaborated with a manufacturing facility in Portugal to design and implement a comprehensive lifting system. The project addressed the need for reliable, high-precision material handling both inside a main workshop and in an adjacent outdoor area. This case details the tailored approach taken to meet the client’s specific operational and spatial requirements.

Client Requirements & Challenges
The client required a robust lifting system to enhance workflow efficiency across their production facility. Key challenges included:

1. Varied Indoor Lifting Needs: Multiple workstations inside the workshop required overhead cranes with different capacities and spans to handle components ranging from 2 to 10 tons.
2. A Precise Outdoor Solution: A requirement for heavy-duty lifting (32 tons) in an exterior yard area, where a traditional overhead crane system was not supported by existing building infrastructure.
3. Space Optimization: Maximizing the use of available headroom indoors and navigating the constraints of the outdoor installation site.
4. Operational Consistency: Preference for uniform, high-quality hoisting mechanisms across all equipment for ease of maintenance and operator familiarity.

The Dongqi Crane Solution: A Two-Part System
Our engineers proposed and delivered a seamlessly integrated solution comprising an indoor overhead crane system and an outdoor semi-gantry crane with full support structure.

Part 1: Indoor HD Series Double Girder Overhead Cranes
A fleet of six overhead cranes was installed within the main workshop, each configured for specific tasks:

• High-Capacity Zones: One 10-ton (span: 16.695m) and one 5-ton crane (span: 16.695m) were deployed for primary heavy-lift operations.
• Flexible Medium-Duty Coverage: Three 3-ton cranes (spans: 16.67m x2, 16.864m) and one 10-ton crane (span: 16.67m) provided versatile coverage for assembly and handling lines.
• Light-Duty Assistance: One 2-ton crane (span: 7.8m) was supplied for lighter, frequent lifts.
• Key Feature – NR European-style Hoists: All HD cranes were equipped with NR-type electric wire rope hoists. Their compact design (low headroom) preserved crucial lifting height (H6M = 6 meters), while offering smooth, precise control and energy-efficient operation for daily industrial use. Standardized 380V, 50Hz, 3-Phase power ensured easy integration.

Part 2: Outdoor BMGO Semi-Gantry Crane with Custom Support Structure
For the 32-ton outdoor lifting requirement, a BMGO semi-gantry crane was the optimal choice.

• The Crane: We supplied a BMGO32T-6.2M H7M unit, offering a 32-ton capacity, a 6.2-meter span, and a 7-meter lifting height (H7M).
• The Turnkey Infrastructure: As the exterior wall could not support the crane runway, Dongqi Crane provided a complete turnkey solution. Our team designed and built a dedicated steel structure anchored to the factory’s exterior wall, along with a robust and precisely aligned runway rail system. This ensured a stable, safe, and high-performance foundation for the semi-gantry crane’s operations, transforming the outdoor area into a functional heavy-lift bay.

Project Execution & Outcome
The project involved precise coordination, from the custom fabrication of crane girders to match exact spans (like 16.695m and 16.864m), to the on-site construction of the outdoor support steelwork. The successful installation resulted in:

• A seamless indoor material flow enabled by the capacity-matched HD crane fleet.
• A powerful and stable outdoor lifting point capable of handling 32-ton loads, fully integrated into the plant’s workflow.
• Reduced operational complexity through the uniform use of reliable NR hoists across all equipment.
• Enhanced overall plant productivity and safety through optimized, right-tool-for-the-job lifting solutions.
