Project: Supply of specialized bridge crane components for a waste processing facility.
Client: A leading waste management and recycling company in Indonesia.
Location: Indonesia
Challenge: To provide high-performance, reliable crane components compatible with locally sourced main girders for a demanding alternative fuel production line.
Solution: A customized package of all electrical and mechanical components for two types of bridge cranes, designed for seamless integration and harsh industrial environments.

Introduction

Dongqi Crane continues to demonstrate its global expertise and flexibility by successfully delivering a critical component package for a sophisticated material handling system in Indonesia. Our client, an innovative waste processing plant specializing in converting municipal and industrial waste into Refuse-Derived Fuel (RDF) or Solid Recovered Fuel (SRF), required robust overhead cranes for their operation. In a collaborative effort to optimize costs and support local industry, Dongqi supplied all essential crane parts except the main girders, which were sourced by the client locally.

This project underscores our commitment to providing adaptable, high-quality solutions that meet the specific logistical and operational needs of our international partners.

The Client’s Challenge

The Indonesian plant’s core business involves sorting, shredding, and processing waste materials to extract high-calorific-value alternative fuels. This process demands durable, reliable, and efficient material handling equipment that can withstand abrasive and corrosive environments. The client needed:

1. Specialized Cranes: Different crane types for handling both raw waste materials (using a grab) and processed material/equipment.
2. Local Integration: A cost-effective strategy involving local procurement of the main girders, requiring a supplier capable of providing a perfectly compatible and complete component kit.
3. Reliability: Equipment with minimal downtime to ensure continuous processing operations.

The Dongqi Crane Solution

Dongqi Crane engineered and supplied a comprehensive package of crane components for six bridge cranes, designed to integrate perfectly with the client’s locally manufactured main girders. All cranes were built to operate on a 400V, 50Hz, 3-phase power supply, standard for the region.

The order consisted of two distinct crane types, each serving a unique purpose in the production line:

• 3 Units of QZ Grab Bridge Cranes (6.3T – 24M Span – H17M): These main girder-less grab cranes are the workhorses of the facility, designed for the intense task of grabbing, moving, and sorting bulk waste materials. Their high lifting height (17m) is ideal for stacking and feeding raw waste into processing hoppers.
• 3 Units of HD European-Style Single Girder Cranes (7.5T – 24M Span – H12.5M): These versatile and energy-efficient cranes are used for general maintenance, handling machinery parts, and moving processed fuel bales. Their compact European design offers excellent hook approach and maximizes available workspace.

Dongqi’s supplied components included:

• High-performance hoists and trolleys
• Robust end carriages with drive mechanisms
• Advanced 400V50Hz3P control systems and electrification
• Safety devices including limit switches and overload protectors
• All necessary software, wiring, and detailed installation documentation

Why The Client Chose Dongqi Crane

• Proven Expertise in Custom Projects: Our ability to dissect a project and deliver exactly what the client needs—not just a standard product—was crucial.
• Seamless Integration Support: We provided all technical specifications and support to ensure the local main girder production aligned perfectly with our components.
• Durability for Harsh Environments: Our components are built to resist dust, moisture, and corrosion, ensuring longevity in a challenging waste management facility.
• Global Supply Chain Capability: We efficiently managed the international logistics of delivering a complete parts kit to the job site on time.

Results and Benefits

The successful deployment of these cranes has provided the Indonesian plant with:

• Enhanced Operational Efficiency: The specialized grab cranes accelerate the handling of raw waste, while the auxiliary HD cranes improve maintenance and logistics flow.
• Significant Cost Savings: The hybrid sourcing model (local girders + Dongqi components) reduced overall project costs without compromising on quality or performance.
• Uncompromised Reliability: Dongqi’s components ensure smooth, continuous operation, which is critical for the 24/7 nature of waste processing and fuel production.

Conclusion

This project is a prime example of how Dongqi Crane partners with global industries to provide intelligent, customized lifting solutions. By supporting the client’s local sourcing strategy for the main girders, we delivered a cost-effective, high-performance system that powers a sustainable business—turning waste into valuable fuel.
