QDGZ 60t Intelligent Double-Girder Bridge Crane for Raw Coal Handling Projects

Resumen del proyecto

In July 2026, four sets of independently developed Weihua QDGZ60t intelligent double girder overhead cranes were officially put into full operation at a coal storage and handling project in Bayannur. Faced with the site’s harsh operating conditions, including extreme low temperatures down to -30°C and high dust pollution prevalent in northern China, we delivered fully customized 60-ton heavy-duty intelligent handling equipment for the project.

Integrating dual working tools of container spreader and hydraulic grab, and equipped with a complete set of intelligent control, precise positioning and safety protection systems, the Weihua crane solutions successfully build an all-in-one digital operation workflow for container coal warehousing inbound and bulk coal loading outbound. The whole process realizes continuous, unattended and intelligent material handling, effectively solving the pain points of low efficiency and high manual cost in traditional coal logistics operations.

Project Challenges & Custom Solutions

The Bayannur coal logistics project faced two major operational pain points before upgrading. First, the local open-air yard suffers from extreme climatic interference, with winter temperatures dropping to -30°C and persistent high dust, which easily causes equipment circuit failure, poor lubrication and unstable operation of traditional cranes.

Second, the yard required two independent handling processes: containerized coal unloading and bulk coal outbound loading. Traditional single-function equipment required repeated machine replacement and scheduling, resulting in low turnover efficiency and high equipment investment and labor costs.

Our Solutions

Weihua crane features a dual-lifting-attachment design that allows for quick switching, catering to two core processes in raw coal storage. The equipment can automatically pick up 20-foot open-top containers and precisely transport them to the stockpiling area for tipping and unloading; after switching to hydraulic grab mode, it can directly perform raw coal transfer operations within the yard and loading operations for off-site transport. A single unit meets both operational needs, eliminating the need to purchase multiple cranes, effectively accelerating material turnover in the storage area, and reducing the customer’s overall equipment investment costs.

The project’s operational area includes the container receiving zone, raw coal storage yard, and railcar loading hoppers. The environment is characterized by consistently low temperatures and high dust levels year-round. We have equipped the QDGZ60t crane with cables rated for temperatures as low as -30°C and specialized low-temperature grease. The electrical system utilizes fully sealed, dust-proof enclosures to prevent dust corrosion. The entire machine meets the A7 high-duty-class standard. It features a double-girder, double-track design paired with a heavy-duty hoist trolley. The main girder has undergone multiple rounds of load verification and is resistant to deformation even under 60-metric-ton heavy-duty, high-frequency operations, resulting in a lower failure rate during long-term operation.
