Double Girder Overhead Crane with Electric Hoist in Industrial Workshop

Exceptional Lifting Capacity for Heavy Loads

Double girder overhead cranes are specifically engineered for demanding lifting operations that require extremely high load capacities. Compared with light-duty or single girder cranes, they can safely and frequently handle much heavier weights without loss of stability or efficiency. Typical capacities range from 30 tons, 40 tons, 50 tons, and 100 tons to 200 tons and even up to 500 tons. This makes them ideal for lifting large steel structures, heavy machinery, power plant components, and molten metal ladles in harsh industrial environments.

Reinforced Structural Design for Long-Term Durability

The overall structure of a heavy-duty bridge crane is built for strength and endurance. Key components such as the main girders, end carriages, trolley frame, and hoisting system are manufactured using high-strength steel and reinforced structural designs. This robust construction allows the crane to withstand repetitive heavy lifting, high working cycles, and continuous operation while maintaining structural integrity and operational reliability.

Advanced Mechanical and Electrical Systems

To meet heavy-duty operational requirements, double girder overhead cranes are equipped with powerful motors, heavy-duty gearboxes, and reliable braking systems. These components are designed to perform under high stress and long operating hours. Advanced cooling solutions are integrated into both mechanical and electrical systems to effectively dissipate heat, ensuring stable performance and extending equipment lifespan.

High Level of Customization for Complex Applications

Double girder overhead cranes offer excellent flexibility in design. Lifting capacity, span, lifting height, duty class, and control systems can all be customized to suit specific working conditions. Whether operating in confined spaces, handling complex lifting processes, or integrating with automated production lines, these cranes can be tailored to deliver efficient and precise material handling solutions.

Engineering & Integrated Design

We provide comprehensive engineering services for steel structure factories equipped with heavy-duty overhead cranes. Our scope includes the integrated design of production halls, crane systems, supporting facilities, and essential infrastructure, ensuring optimal layout, structural safety, and efficient material flow from the outset.

Procurement & Supply Coordination

Through centralized procurement, we supply steel structures, overhead cranes, utility systems, and auxiliary equipment under unified quality standards. This approach ensures consistency in materials, reliable performance, and effective cost control throughout the project lifecycle.

Construction & Installation

Our construction services cover steel structure workshops, office buildings, auxiliary facilities, internal roads, and complete utility networks. Heavy-duty crane installation is carried out under unified site management, ensuring safety, schedule control, and seamless coordination between civil works and equipment installation.

Testing & Commissioning

We conduct systematic testing and commissioning of overhead cranes, power supply systems, drainage, and utilities. This phase verifies performance, safety, and reliability, ensuring all systems are fully operational and meet design requirements.

Project Handover & Acceptance

Upon completion, we deliver as-built drawings, full technical documentation, and operator training. Final inspection and acceptance are carried out to confirm compliance with contractual and technical standards.

Operation, Maintenance & After-Sales Support

Our services continue after handover, offering long-term operation and maintenance support, maintenance planning, spare parts supply, and ongoing technical assistance for cranes, steel structures, and facility systems.
