Product Introduction
Double Trolley Double Girder Crane is a high-capacity material handling solution equipped with two main box girders and two independently operated trolleys. Specially designed for long-span and heavy-duty applications, it allows precise, coordinated lifting of oversized, ultra-wide, or extra-long loads.

Product Advantages
Dual Trolley Versatility
Features two independent trolleys that can operate separately or in tandem to lift, flip, and precisely maneuver long or unwieldy materials with superior stability.
Heavy-Duty Capacity Options
Available in dual-trolley combined configurations such as 5+5t, 10+10t, 20+20/5t, 50+50/10t, and up to 100+100/20t.
Robust Structural Design
Employs heavy-duty box-type main girders—accounting for approximately 60% of total crane deadweight—to serve as the primary load-bearing architecture.
International Standards & Quality
Engineered and manufactured in compliance with ISO9001, CE, and GB/T14405 international standards.
Typical Application Scenarios
Shipbuilding & Marine Fabrication
Ideal for handling, turning, and positioning massive ship sections and heavy structural components during assembly.
Industrial Manufacturing & Mining
Used in workshops, steel yards, and warehouses for loading, unloading, and staging extra-wide or long heavy cargo.
Long-Span Heavy Operations
Provides enhanced stability, load balance, and precise control compared to single-trolley cranes when handling complex, heavy industrial loads.
