  • Span: 4.5 - 31.5m
  • Lifting Height: 3 - 30m
  • Working Duty: A4 - A7

Overview

Double girder overhead cranes are designed to handle heavy-duty lifting tasks with exceptional strength, precision, and stability. Unlike single girder cranes, they feature two parallel girders, which provide greater rigidity and load-bearing capacity — making them ideal for applications that demand maximum lifting height, longer spans, and continuous operation.

These cranes are commonly used in steel fabrication plants, heavy machinery workshops, power stations, and large warehouses, where reliable performance and safety are essential. The hoist trolley runs on rails mounted on top of the two girders, allowing for higher hook positions and efficient use of vertical space.

Double girder overhead cranes can be equipped with electric wire rope hoists or open winch trolleys, depending on the lifting capacity and working conditions. A variety of optional features, including variable frequency drives (VFDs), anti-sway systems, radio remote controls, and overload protection, can be integrated to enhance precision and safety.

Advantages

1. High Load Capacity & Extreme Durability

Double girder overhead cranes are engineered for maximum strength and reliability, capable of handling the heaviest loads with minimal structural deflection. Their robust welded box girders and reinforced end beams ensure consistent performance, even in the most demanding industrial environments. This durability reduces maintenance requirements and extends service life.

2. Maximum Hook Height & Extended Reach

Compared to single-girder cranes, double girder overhead cranes provide higher hook lifting heights and longer spans. This allows access to tall storage areas, large workspaces, and elevated structures, maximizing operational efficiency. Extended reach reduces the need for additional lifting systems and optimizes workflow in large plants.

3. Customization & Versatility

Double girder overhead cranes can be fully customized to meet specific operational needs. Options include variable lifting speeds, automated or semi-automated operation, specialized attachments for unique materials, and designs suited for extreme environments such as high temperature or explosive atmospheres.

4. Advanced Safety Features

Safety is a priority. Double girder overhead cranes are equipped with overload protection, emergency stop controls, high-performance brakes, travel limit switches, anti-sway mechanisms, and monitoring systems. These features ensure reliable operation and protect both personnel and equipment.

5. Superior Performance & Precision

These cranes offer precise load control and smooth, stable movement even under heavy loads. Multiple hoist configurations and advanced control systems allow optimized lifting for complex applications, ensuring maximum efficiency and productivity.

Double-Girder Design Benefits

1. Optimized Design for Facility Requirements

Our team specializes in designing double girder overhead crane systems tailored to your facility. By carefully analyzing space limitations, load requirements, and operational workflows, we deliver crane solutions optimized for maximum efficiency, safety, and productivity in your specific application.

2. Structural Superiority

The dual-girder construction of a double girder overhead crane provides exceptional strength-to-weight ratio. It significantly reduces beam deflection under heavy loads, enabling longer spans and higher lifting capacities compared to single-girder cranes. This structural robustness ensures consistent performance and longevity in demanding industrial environments.

3. Enhanced Stability

Double girder overhead cranes feature a cross-tied girder design that eliminates lateral movement, providing superior load stability during lifting and traveling operations. This stability minimizes load sway, reduces stress on the hoist and rails, and enhances operator confidence and safety.

4. Maintenance and Inspection Access

Top-running hoists on double girder overhead cranes allow easy access to key components for maintenance and inspection. Motors, gearboxes, brakes, and electrical systems are reachable without disassembling the crane, simplifying upkeep and reducing downtime.

5. Versatility and Customization

The double girder design accommodates a wide range of hoist configurations, specialized attachments, and optional automation systems. This versatility allows the crane to meet diverse industrial requirements while maintaining high performance and safety standards.

Double girder overhead cranes combine structural strength, operational stability, and ease of maintenance, making them the ideal solution for heavy-duty lifting and high-demand industrial applications.
