On the construction site, several golden double-girder mobile gantry cranes (equipped with dual electric hoists) resemble "steel giants," standing out against the clear blue sky and firmly occupying the centerpiece of lifting operations.

Technical Parameters:

Their dual-girder structure and dual electric hoist configuration offer a perfect combination of power and efficiency. Clearly marked on the equipment is a 10-ton lifting capacity. The dual electric hoists can collaborate to lift extremely large components or independently handle various materials, ensuring smooth movement of heavy objects in mid-air and significantly reducing loading, unloading, and transport time.
Even more remarkable is their mobility: their built-in mobile mechanism allows the massive crane to maneuver flexibly around the site. For example, during prefabricated component production, molds and finished products can be precisely hoisted; during the installation of large equipment, heavy components can be smoothly transferred; even the efficient handling of scattered heavy objects on site is accomplished through the flexible mobility and collaboration of the dual hoists. The eye-catching yellow frame is not only instantly recognizable, but also undergoes special reinforcement technology to ensure maximum durability, even in the dusty and sometimes bumpy environments of construction sites. With it, the lifting process is no longer a bottleneck for project efficiency, but instead becomes an accelerator that accelerates project progress. It is truly an indispensable "golden crane" for engineers.

Core Use Cases for the Double-Girder Mobile Gantry Crane (Dual Electric Hoist)

Leveraging the characteristics of "strong dual-girder load-bearing capacity + flexible dual hoist operation + wide mobile coverage," this equipment precisely adapts to various heavy-duty, high-frequency lifting needs on construction sites. Key use cases are as follows:

1. Prefabricated Building Construction Sites

In prefabricated residential and factory construction projects, it is a core tool for lifting prefabricated components. It efficiently lifts heavy components (mostly weighing 5-10 tons each), such as precast concrete beams, composite slabs, and wall panels. The dual electric hoists coordinately adjust component levelness to prevent tilting during lifting. Combined with its mobile chassis, it allows for flexible switching between work locations within the construction site, moving components from the storage area to the building installation site. Frequent adjustments to the equipment foundation are eliminated, significantly shortening component lifting cycles.

2. Heavy Equipment Installation Sites
For factory equipment upgrades and installation of supporting equipment for large-scale projects (such as generators, boilers, and large machine tools), the system meets the "heavy load + high-precision" lifting requirements. The dual-beam structure can stably support equipment up to 10 tons. Dual electric hoists can hook onto the equipment at either end, allowing precise equipment alignment (such as horizontally shifting a machine tool onto pre-buried guide rails) by fine-tuning the hoist lifting speed. This prevents equipment shifting during single-hoist lifting and reduces installation errors. 3. Heavy-Duty Storage and Logistics Transfer Area
In storage yards or logistics transfer stations for goods such as steel coils, large packaging boxes, and heavy parts, this crane can achieve "wide-scale and high-efficiency" transfer. The mobile crane can cover the entire area of ​​the yard, eliminating the need for fixed hoist rails. The dual electric hoists can operate independently (to lift two batches of light cargo simultaneously) or collaboratively (to lift a single batch of heavy cargo). For example, they can simultaneously unload two steel coils from a truck into a designated storage area or transfer 10-ton large machinery parts in a single operation, improving cargo turnover efficiency. 4. Metallurgical and Heavy Manufacturing Workshops
In production scenarios such as steel mills and heavy machinery plants, this hoist meets the demands of "harsh environments and high-frequency lifting." The equipment is dust-resistant and resistant to minor impacts, enabling stable operation during the transfer of steel billets and the processing of heavy machinery parts in metallurgical workshops. For example, high-temperature steel billets (weighing 8-10 tons each after cooling) in steel mills can be lifted from the cooling area to processing machine tools, or large gears, bearings, and other parts can be transferred to various production line stations in heavy machinery plants. The flexible operation of the dual hoists adapts to the lifting needs of different work-pieces, ensuring production continuity.
