Double-girder gantry cranes are built for high-capacity, long-span lifting in demanding industrial environments.

With a robust dual-girder structure, double-girder gantry cranes deliver superior strength, stability, and lifting precision—perfect for heavy loads, oversized materials, and large work areas such as shipyards, precast yards, and fabrication plants.

Designed for durability and engineered with advanced control systems, Daswell gantry cranes ensure smooth movement, precise load handling, and long-term operational reliability. When strength, scale, and performance matter, Daswell delivers.

Double girder gantry crane

• The gantry crane is mainly used for bridge construction and consists of a gantry, hoist trolley, trolley running mechanism, driver’s cab and electrical control system.
• The portal frame is a truss structure, which has the advantages of light structure and strong wind resistance, including the main beam, upper end beam, outriggers, lower end beam, traveling trolley and walking platform railings, إلخ.
• The main beam adopts a triangular truss structure, on which a track is laid for the trolley to move laterally along the direction of the main beam. The outriggers come in two forms, box-shaped or steel pipe.
• The trolley is arranged with a winch and is compact and lightweight.

Characteristics of gantry crane

• There are three modes of operation: ground handle, wireless remote control, and driver’s cab;
• The power supply is available in the form of cable reels and high-altitude slide wire;
• Select high-quality steel, with high strength, lightweight, and not easy to deform;
• Solid base, small footprint, small dimensions above the track surface, and fast running;
• It is mainly composed ofa gantry (main beam, outriggers, lower beam, إلخ.), آلية الرفع, operating mechanism, and electric control part. The electric hoist is used as the lifting mechanism, and it runs along the lower flange of the main beam I-beam during work;
• The gantry structure is divided into two types: box shape and truss. The box shape has good craftsmanship and is easy to manufacture; the truss is lightweight and shas trong wind resistance;
• تصميم وحدات, short design cycle, high degree of generalization, improve the utilization rate of parts;
• Compact structure, small size, large working range, effectively improve production efficiency;
• Full frequency conversion control, عملية مستقرة, no impact, slow speed under heavy load, fast speed under light load, energy saving, and consumption reduction.
