Case Study: Dongqi Crane Powers Indonesian Waste-to-Fuel Innovation with Custom Crane Solutions

Summary:
Dongqi Crane partnered with a leading waste processing plant in Indonesia to supply critical overhead crane components for their new alternative fuel production line. By providing a complete kit excluding the main girders—which were sourced locally by the client—Dongqi delivered a cost-effective, flexible solution that ensures reliable and efficient handling of waste materials.

The Client:
Our client is an innovative Indonesian company dedicated to sustainable waste management. Their factory specializes in converting municipal and industrial waste into Refuse-Derived Fuel (RDF) and Solid Recovered Fuel (SRF), providing a cleaner alternative to fossil fuels and reducing landfill waste.

The Challenge:
The client was constructing a new processing line that required robust overhead cranes for handling raw waste materials and processed fuel. The challenges were multi-faceted:

• Harsh Environment: The cranes would operate in a demanding environment with dust, abrasion, and potential corrosion.
• Diverse Handling Needs: The application required both grabbing loose, uneven waste and precise handling of processed fuel bales.
• Cost Efficiency: The client sought a strategic solution to manage project costs without compromising on quality or reliability, opting to fabricate the main girders locally in Indonesia.

The Dongqi Crane Solution:
Understanding the client’s specific needs, Dongqi Crane engineered a tailored package of high-quality crane components designed for durability and performance. We supplied all necessary parts for six cranes, except for the main girders, which were purchased locally by the client based on our provided technical specifications.

The order consisted of:

1. 3 x QZ Main Girder-Less Grab Bridge Cranes (6.3T – 24M Span – 17M Lift)
   • Purpose: These robust cranes are designed for the initial stage of the process, grabbing and moving raw, unprocessed waste from the tipping floor to the sorting and shredding machinery.
   • Key Feature: The grab mechanism is essential for handling bulk, loose materials efficiently.
2. 3 x HD European-Style Single Girder Bridge Cranes (7.5T – 24M Span – 12.5M Lift)
   • Purpose: These versatile and energy-efficient cranes are used for handling baled alternative fuel (SRF/RDF) and maintaining machinery within the plant.
   • Key Feature: The compact European design offers excellent hook coverage and is ideal for precise load placement in a busy workshop environment.

Technical Specifications:

• Power Supply: All crane components are designed for a 400V, 50Hz, 3-phase power system, standard for Indonesia.
• Durability Features: Components were selected with enhanced protection for dust and abrasive conditions.

Why This Solution Worked:

• Cost-Effective Collaboration: Our model of supplying all components except the locally sourced main girders significantly reduced the client’s overall costs for shipping and import duties.
• Seamless Integration: Our engineering team provided detailed specifications and documentation to ensure the locally manufactured girders perfectly integrated with our supplied end carriages, hoists, and control systems.
• Application-Specific Expertise: We provided the exact right tool for each job: powerful grab cranes for raw waste and precise, efficient single-girder cranes for finished product handling.
• Uncompromised Quality: Even though the girders were local, the client received Dongqi’s renowned quality in all critical components like hoists, motors, and electrical systems, ensuring long-term reliability.

The Result:
The client successfully installed the cranes and launched their new production line. The Dongqi-equipped cranes now play a vital role in a sustainable operation, helping to turn waste into valuable energy resources. The project is a testament to a successful international partnership and Dongqi Crane’s flexibility in providing innovative, tailored material handling solutions.
